说明

一般描述

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. [1]

应用

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.[2]
• Mobile phase for high-performance liquid chromatography (HPLC), enabling the effective separation of TMP (trimethoprim) and SMX (sulfamethoxazole).[3]
• For sample preparation, including extraction, dilution, and dissolutionof compounds prior to analysis.
