摘要:

The physically and chemically stable and batch-to-batch reproducible bonded phases of wide-pore size (300Å) were developed by using silica gels of purity over 99.99%. The chemically modified silica gels of butyl, pentyl, and octadecyl bonded phases were stable and inert for over 10,000 hours immersion in aqueous 1.0% trifluoroacetic acid (pH 1.5):CH3CN-50:50 and 20 mM sodium phosphate buffer (pH 10.0):CH3CN-50:50.
