Application
Acetonitrile can be used as a component in:
- Mobile phase mixture for the HPLC analysis, to determine the purity of ester content (%FAME).
- Mobile phase for the ultra-performance liquid chromatography (UPLC) analysis of perfluoroalkyl carboxylic and sulfonic compounds.
- Mobile phase for high-performance liquid chromatography (HPLC), enabling the effective separation of TMP (trimethoprim) and SMX (sulfamethoxazole).
- For sample preparation, including extraction, dilution, and dissolutionof compounds prior to analysis.
General description
Acetonitrile is a widely used organic solvent in reversed-phase liquid chromatography due to its high miscibility with water, suitable UV absorbance properties, and low viscosity characteristics.
