설명

일반 설명

Acetonitrile (MeCN) is widely employed as a solvent in various studies and has high dielectric constant (37.5). Various purification procedures to obtain different grades of acetonitrile for use in different studies (polarography, spectroscopy, etc.) have been reported by many researchers.

애플리케이션

Acetonitrile has been used to compose the gradient system for the HPLC detection of diphenylmethane diisocyanate, a polymeric degradation product.

New Quality UPLC Plus Acetonitrile is suitable for all applications including:
Mass spectrometry, HPLC, TLC, GPC, UV, IR, GC, Pesticide Residue Analysis, and RNA/DNA Synthesis and Purification.
