In recent years, biofuel (biodiesel) is becoming increasingly popular in the world, a type of fuel derived from renewable resources with environmentally friendly combustion products. According to GOST R 52808-2007: “Non-conventional technologies. Bio-waste energy. Terms and definitions” biofuel is a solid, liquid or gaseous fuel obtained from biomass by thermochemical or biological methods.

Liquid biofuels are a promising class of fuels, the main use of which is engines. Liquid, or as it is also called, motor biofuel is obtained during the processing of vegetable raw materials (maize, rapeseed, sugar beet, sugar cane) by means of technologies based on the use of natural biological processes (for example, fermentation). Liquid biofuels are commonly understood as alcohols (methanol, ethanol, butanol), ethers, and biodiesel.

There are a number of solutions used for biofuel analysis 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
• Monitoring the process of enzymatic hydrolysis of cellulosic biomass
• Accelerated solvent extraction of biomass fats
• Determination of anions in organic solvents
• Alcohol Fermentation Monitor (AFM)
