Water analysis
We offer you two articles on water analysis using two analytical methods:
Water analysis by ion chromatography. The possibilities of the method and technical solutions of the company Dionex Corporation, USA.
Article, author Rybakova E.V.
Ion chromatography allows to determine inorganic and organic anions, cations of alkaline and alkaline earth metals, transition metal cations, amines and other organic compounds in ionic form. Although many different methods are used for the analysis of water, ion chromatography (IC) is a priority method worldwide and provides a multicomponent determination in all waters. Each type of water has its own characteristics and components that can vary significantly in concentration from fractions of µg/l to units of g/l. Particularly important is the identification of water hazardous components that are undesirable or unacceptable in the water. Prior to the appearance of IC, there was no effective method of determining ions with such sensitivity, selectivity, reproducibility and speed of analysis. In most cases, however, the IC analysis does not require sample preparation: if necessary, the sample is filtered and diluted. Analysis of inorganic anions such as fluoride, chloride, nitrite, nitrate, sulfate and phosphate by the IR method has been the most common and routine analysis in the world for many years. Highly efficient columns for the determination of chlorite, chlorate, prechlorate, etc. have been developed and successfully used. Dionex’s high-performance columns enable the simultaneous determination of alkali and alkaline earth metal cations and aliphatic and aromatic amines on a single x-ray column – a well-designed, highly efficient and fast method of analysis for a very wide range of the most commonly identified analytes in waters of all types. The absence of complex sample preparation, high sensitivity, rapidity of analysis and a wide variety of detectable components in water make it ideal for analytical laboratories performing routine analysis of water of all compositions, from high purity and drinking water to effluent and emissions from enterprises and utilities.
Inorganic anions
Analysis of inorganic anions such as fluoride, chloride, nitrite, nitrate, sulfate and phosphate by ion chromatography has been the most common and routine analysis worldwide for many years.
In addition to ion chromatographic columns for the determination of basic inorganic anions, highly efficient columns have been developed and are successfully used for the determination of such standard anions and oxyonions as oxychalides as chlorite, chlorate, prechlorate, etc.
Organic acids
In addition to inorganic anions, organic anions such as acetate, formate, propionate, oxalate, citrate, etc. may also be present in various types of water. Highly efficient, high-capacity analytical columns are used for these applications.
Inorganic cations
Highly sensitive and highly effective ionochromatographic determination of alkali and alkaline earth metal cations is also a routine method of analysis in the world analytical practice. The figure shows a chromatogram of fast isocratic separation of cations of groups I and II.
Toxic pollutant analysis
Methods for identification of pollutants in water
To solve this problem, instrumental methods of modern analytical chemistry are used, based on the measurement of various physical and chemical properties of defined substances or products of their chemical transformations with the help of analytical instruments.
An exceptionally powerful means of controlling pollution of various environmental objects is chromatographic methods that allow analyzing complex mixtures of components. Gas and high-performance liquid and ion chromatography have acquired the greatest importance. Gas chromatography is effective in the analysis of multicomponent mixtures of volatile organic substances.
High-performance liquid chromatography (HPLC) is used in the analysis of mixtures of many pollutants, especially non-volatile ones. Using highly sensitive detectors: spectrophotometric, fluorimetric, electrochemical, it is possible to determine very small amounts of substances. The combination of chromatography and mass spectrometry is particularly effective in the analysis of complex mixtures. Pesticides, polychlorinated biphenyls, dioxins, nitrosamines and other toxic organic compounds are determined by HPLC.
In order to analyze traces of organic water pollutants, extraction and concentration are required due to the very low concentrations of these substances. The AutoTrace Automated Solid State Extraction System and Rocket Solvent Evaporator are invaluable.
Ion chromatography is convenient for the analysis of cationic and anionic compositions of different types of water. The types of water used in the production process may vary depending on the application; municipal drinking water, whose composition control is a major public health concern; ultrapure water, which is used in thermal and nuclear power plants, requires special control; and finally, waste water and emissions from enterprises and utilities. Thus the analysis by a method of ionic chromatography in most cases does not demand sample preparation: if necessary the sample is filtered and diluted. In addition, ion chromatography, in contrast to outdated routine “wet chemistry” methods, allows for the immediate identification of a group of ions, such as inorganic anions and organic acids in one analysis, or alkaline, alkaline earth metals and amines in one analysis. The components of the sample can be in different concentration ranges.

Oil and oil refining industryThe oil production and refining industry plays a significant role in the economy of our country. The consequences of the global economic crisis, environmental problems and rising energy prices have become an incentive to create better products. In the conditions of the aggravated competition in the Russian and world markets it is especially important to produce high-quality oil products that meet not only the requirements of GOST, but also the requirements of international standards, such as ASTM (American Society for Testing and Materials), CEN (European committee for standardization) and UOP (Universal oil product). Quality control is a very important problem, which will help you to solve the equipment we offer. Analysis of petroleum products and fuel oil
Analysis of natural waters, technological and sewage during oil refining and extraction, as well as transportation of oil and petroleum products
Analysis of petroleum products and fuel oilElemental analysis of oil and petroleum productsFor the analysis of oil and petrochemicals, the precise quantification of carbon, hydrogen, nitrogen, sulfur and oxygen elements is essential for both the determination of the basic elements and the elements present in trace concentrations, such as nitrogen and sulfur. Each case requires a high degree of accuracy, repeatability and stability of the analysis. This is particularly true in the lowest concentration range. Elementar Analysensysteme, a German manufacturer of analytical equipment, has more than 100 years of experience in the development of elemental analysis analyzers for organic compounds. The line of vario EL cube and vario Trace SN analyzers has been specially developed and optimized for the analysis of oil and oil products. The vario Trace SN range has been developed for the highly sensitive and precise determination of sulphur and nitrogen in hydrocarbons, gasoline, oil and gases in order to fully comply with the modern requirements of petroleum product quality and environmental protection due to its low detection limits. These elemental analyzers meet the following standards: ASTM D 4629, ASTM D 5453, D 6667, UOP 987, UOP 981, etc. Difficult to select the right model? – Contact us! Aromatic hydrocarbons in petroleum products and fuel oilRecently, the issue of aromatic hydrocarbons content in various petroleum products and fuels has been very acute. According to GOST 12916-2008, as well as ASTM D6379-11 and IP 391, the method of determining the mass fraction of monoaromatic, diaromatic and tri- and polyaromatic hydrocarbons by the method of high-performance liquid chromatography with refractive index detection is established. The IP 391 standard, in particular, establishes a method for determining the content of monoaromatic, diaromatic and polyaromatic hydrocarbons in diesel fuels and oil distillates boiling at temperatures ranging from 150°C to 400°C. The IP 368 standard establishes a method for determining the content of saturated and aromatic hydrocarbons in lubricating oils boiling at temperatures above 270°C. The same method is applicable for gas oils boiling in the temperature range from 200°C to 350°C. Both methods involve the use of a high-performance liquid chromatograph with a refractometric detector, but in different configurations. We offer you a solution that combines all of these methods on a single chromatograph: Dionex UltiMate3000 liquid chromatograph. The above methods are implemented on HPLC UltiMate3000 in a configuration that includes an isocratic pump, a thermostat with column and flow reversal and switching valves, a manual injector and a convenient fraction collector Polycyclic hydrocarbons are harmful to human health because they are carcinogenic substances and also affect fuel quality, engine performance and engine life, so the need to analyse their content in the fuel cannot be overestimated. Using the Dionex UltiMate 3000 x2 dual system, you will be able to analyze the polycyclic aromatic hydrocarbon content of the fuel in accordance with the ASTM D-6591 methodology. For a commercial offer, please contact us. Ion chromatographic determination of halogens and sulfur in petroleum products after combustion (Combustion IC)The presence of large quantities of fluorine, chlorine, sulphur and bromine can cause corrosion in many industrial processes, emit harmful substances into the environment, and reduce the lifetime of catalysts. With the help of ion chromatography you can easily carry out qualitative and quantitative analysis of the content of halogens and sulfur in petroleum products, carbon, building materials and various polymers. The method of analysis on our equipment complies exactly with the standard ASTM D7359-08, as well as ASTM D 6809 The solid or semi-solid samples are pyrolysed at about 10,000 C for a few minutes in an oxygen or air stream, the volatile products are then absorbed by an aqueous solution and the sample is injected into an ion chromatographic system for the analysis of the combustion products, the entire process being fully automated Dionex company’s solution for this technique: Dionex ICS-2100 ion chromatograph with IonPac AS11-HC ion separation column. As an alternative, it is possible to use the ICS-1600 or ICS-1100 systems – systems with manual eluent preparation. For questions about the equipment, you can always contact our specialists. Oil products in various environmental objects. Preparation of samples for analysisTo extract petroleum products from different environmental objects, Dionex offers different types of extractors, depending on the type of substance being analyzed, all procedures are performed in accordance with ASTM methods. If you need to isolate polluting hydrocarbons (benzene, toluene, xylene, diesel fuel, etc.) from the soil for further quantitative analysis, rapid solvent extraction is the ideal choice for you. The Dionex ASE 350 (automatic extraction) or Dionex ASE 150 (semi-automatic extraction) system will help you to carry out the most efficient extraction process in a short time, using the minimum amount of solvents, in accordance with the international EPA 3545 method. Dionex also offers a solution for determining the total hydrocarbon content of water. The method complies with the EPA 1664 standard The AutoTrace 280 system performs automated solid-phase extraction from a large volume of liquid. To learn more about the technique, read the article “Automatic solid phase extraction of oil carbohydrates using the Dionex AutoTrace tool”. In this article, you will find information about the various analysis methods for industrial oil and gas refining processes and the production and use of biofuels. Analysis of natural waters, process and waste waters during oil refining and production, as well as during transportation of oil and oil productsIon chromatography is a universal method for the analysis of all types of water. Fast, highly sensitive, multi-component and selective determination of a large number of inorganic and organic substances in ionic form (anions and cations) makes this method absolutely necessary for use in any laboratory dealing with water analysis. Determination of impurities of anions and cations in high purity waters, control of ions concentrations in process waters and ecological control of waste water are examples of routine applications of this method in industry. These tasks are carried out on Dionex ICS-5000 or Dionex ICS-2100 laboratory systems (with automatic eluent generation), ICS-1600 or ICS-1100 (if the eluent is prepared manually), as well as on Integral (ICS2100) and Integral (ICS5000) industrial on-line systems in case of automatic water quality control in production. If atmospheric air needs to be analyzed for solvents, BTX compounds, oil products in water, or VOCs/PLOCs, TRIDION™-9 GC-TMS analyzer in combination with a CUSTODION® solids micro-extraction syringe will allow for on-site chemical analysis to detect, recognize, quantify and quantify these substances. Groundwater and formation water analysisIn the practice of oil and gas hydrogeology, the study of the microelement composition of water is limited, as a rule, to the traditional range of specific elements, including bromine, iodine, boron, iron, ammonium ion and some others. The determination of such ions as lithium, rubidium, cesium, magnesium, calcium, strontium, and barium (cations), as well as fluoride, chloride, sulfate, and phosphate in the deep underground waters of oil and gas provinces are of both scientific and practical interest. The determination of this entire set of ions is possible either on a two-channel ion chromatographic system (Dionex ICS5000), or on a complex of two ion chromatographs combined by a single autosampler and software. Analysis of drilling fluidsTo ensure that the drilling process is as efficient as possible and that the equipment is not exposed to harmful effects, the composition of the drilling fluids must be carefully controlled. In addition, certain requirements to the composition of drilling fluids are put forward by environmentalists, as it has been proved that drilling and fracturing in the formation affect the composition of groundwater, which can later affect the composition of drinking water. API (American Petroleum Institute) standards are often used for drilling fluid analysis. With the help of our equipment it is possible to solve the problems of determining the content of calcium and magnesium ions, chlorine ions, analysis of rigidity and alkalinity To determine these ions, a two-channel chromatographic system (Dionex ICS5000), or a set of two chromatographs, combined with a single autosampler and software, is suitable.

One of the main technological challenges for all power plants is to ensure that the water used for power generation is of such a high purity that it is of such a quality that it meets the specified parameters. Ion chromatography (IC) is the main method of water quality control for corrosion parameters. Anions, transition metal cations, silicates, boron can be controlled in feed water, feed water, chemically unsalted water, condensate, purge water, etc.
Other applications of ion chromatography in the power industry include the control of chemically treated water, quality control of high purity chemicals used in process water preparation, and waste and disposal analysis. IR can be used in the nuclear power industry to monitor a nuclear accident and to analyse the waters of a single- and dual-circuit reactor.
Recent advances in ion chromatography, such as eluent generation and the process analyzer, have provided significant usability and reproducibility. Given these advances, ion chromatography has become a valuable method for both types of power plants to monitor different water flows, environmental samples, and clean chemicals.

- How to determine the ractopamine content of meat?
We know and offer a solution!
RactopamineRACTOPAMIN is a substance used as a feed additive in animal husbandry to build muscle mass in animals. It is a β-adrenergic agonist belonging to the class of fenethanolamines. Ractopamine was approved by the U.S. Food and Drug Administration (FDA) in 1999 (and by the Canadian Food Inspection Agency (CFIA, Canadian Food Inspection Agency, under the Paylean® brand in 2005) for use in the pork industry, and for cattle in early 2003.
Rosselkhokhznadzor introduced a ban on the import of meat containing ractopamine into Russia, which is why the Russian regulatory laboratories were faced with the issue of fast and reliable methods of determining the content of this substance.
We offer you our solution to this analytical problem!
1. Sample preparation.
ASEUtilization of Accelerated Liquid Extraction (ASE) with organic solvents (mixture of acetonitrile: isopropanol, 4:1) on ASE 150 or ASE 350 extractors allows to transfer the sample substance from solid to liquid in a few minutes and with high reproducibility.
2. in-line solid-state extraction (in-line SPE) eliminates the need for manual evaporation and redissolution of the extract for subsequent chromatography. At this stage, a cation exchange polar HPLC column is used to isolate the necessary components. It adsorbs the required substances and is then washed with organic solvents to remove a number of interfering components, such as fats. This process is carried out on the Dionex UltiMate 3000 RSLC Dual dual chromatographic system equipped with an autosampler.
3. chromatographic separation
After the in-line solid phase extraction procedure, the analyzed components are fed to the analytical non-polar column Acclaim C30 for chromatographic separation and subsequent identification of components on the spectrophotometric detector.

The water used in the production of semiconductors and other modern electronic components must be extremely clean. The water is subjected to deep cleaning to remove ions. Deionising plants must be replaced or regenerated periodically. When the time of their efficient operation is nearing its end, one of the first ions to break through the ion exchange filter and contaminate the water will be a silicate ion.
Silicate can be contained in water, even with an electrical conductivity of 18 MΩ-cm. Therefore, silicate is a good indicator of resin depletion. Early diagnosis of the level of silicate concentration can help prevent the production failure of expensive electronic components. This is where trace analysis is absolutely necessary. Dionex invented AutoPrep to eliminate the potential impact of contaminants on the process. The combination of the RFIC™ system and AutoPrep reduces sources of contamination and operator error, ensuring accurate trace analysis

Authentication and quantitative chromatographic analysis.
There are several common methods of qualitative and quantitative analysis of ademetionine and its preparations, of which highly effective liquid chromatography (HPLC) and ion chromatography (IC) are the most informative ones, as they allow not only to reliably identify substances, but also to determine the quantitative content of not only the active ingredient, but also by-products and other impurities. Therefore, the chromatographic solution described in this article will be interesting not only for producers of substances and drugs based on it, but also for control laboratories, whose task is to assess the quality and authenticity of drugs on the domestic market. It should be especially noted that the use of HPLC and HPLC is the most budgetary solution, which is important for users.
Chemical industryAny chemical enterprise has in its composition an analytical laboratory engaged in quality control of products, analysis of technological process and development of recommendations on its adjustment. Objectives of such laboratories cover a wide range of problems arising in the course of work of the enterprise, however their effective decision is impossible without availability of the qualitative analytical equipment. Often the installation of a single device allows you to save hours, and sometimes even a day, to conduct more analysis, to complicate the task. Thus, the system of ion chromatograph, elemental analyzer and automatic extractor is able to reduce the time spent by personnel on daily analytical procedures by more than 80%. Oil refining:

Biofuel and biodiesel
In recent years, biofuels (biodiesel), a fuel derived from renewable resources with environmentally friendly combustion products, has become increasingly popular worldwide. According to GOST R 52808-2007: “Unconventional technologies. Bio-waste energy. Terms and definitions”, biofuels are solid, liquid or gaseous fuels derived from biomass in a thermochemical or biological way.
Liquid biofuel is a promising fuel class, the main application of which are engines. Liquid, or as it is also called, motor biofuels are produced by processing vegetable raw materials (corn, rapeseed, sugar beet, sugar cane) by means of technologies based on the use of natural biological processes (for example, fermentation). Liquid biofuels are usually understood as alcohols (methanol, ethanol, butanol), esters and biodiesel.
There are a number of solutions for the analysis of biofuels on Dionex equipment:
- Determination of anions in ethanol and methanol
- Determination of anions in biobutanol
- Determination of cations in biofuels
- Determination of fat and carbohydrate content in biofuel feedstock
- Biomass composition analysis
