Application Range

Primarily used for analyzing the composition of electrolytes. It can qualitatively identify solvents and additives in the electrolyte. In addition, it can quantitatively analyze 7 types of carbonate solvents (DOL, DME, DMC, EMC, DEC, EC, PC) and 4 types of additives (VC, FEC, PS, VEC). The quantitative error for the main solvents is approximately 1-3%, while the quantitative error for additives is within 5%.
