Publikováno v: Journal of chromatography. A. 1339

A high-density, polymeric C18 stationary phase (Inertsil ODS-P) or a polymeric C30 phase (Inertsil C30) provided improved resolution of the isomeric fatty acids (FAs), FA methyl esters (FAMEs), triacylglycerols (TAGs), and tocopherols with an increas

Development of a new cyano-bonded column for high-performance liquid chromatography

Autor: H Tanaka, Masayoshi Ohira, Kensuke Okusa

Publikováno v: Journal of chromatography. A. 869(1-2)

A unique cyano-bonded column for high-performance liquid chromatography was developed by chemically bonding cyanopropyl groups to the silica gel support, and its chromatographic performance was described. Eight cyanopropyl-bonded silica gels were pre
