The application of HPLC to the analysis of chiral substances is increasing rapidly. This is particularly important in the pharmaceutical industry where information on enantiomeric composition is being required. In many biological processes the activity of one isomer can be contrasted with the inactivity or even harmful effect of the other. ES Industries offer several different types of chiral stationary phases to handle the wide variety of chiral separation problems.
ES Industries offers either optically active phenylglycine or leucine derivative bonded to the silica surface (Pirkle types). Since these optically active compounds are chemically bound to the silica surface there is no restriction on the polarity of the mobile phase.
