New Analytical Method Using Polar Modifiers in Supercritical Fluid Chromatography and Its Application to the Separation of Fatty Alcohol Ethers

  • Published : 1996.06.20

Abstract

Fatty alcohol ethers, nonionic surfactants which are used as general purpose emulsifiers were separated by use of water-modified carbon dioxide mobile phase in capillary supercritical fluid chromatography. Much greater peak intensities and improved separation were observed in the chromatogram with on-line modified mobile phase than with pure CO2. A simple method for the preparation of on-line modified mobile phase is also introduced.
