title: Analysis of bile acids in serum and bile by capillary gas-liquid chromatography.
abstract: Various liquid phases for glass capillary columns have been evaluated for gas-liquid chromatographic analysis of methyl ester trimethylsilylether derivatives of bile acids from serum and bile. Bile acid analysis is rapid and exhibits high separation efficiency with a 20 X 0.3 mm glass capillary column whose internal surface is covered with a crystal layer of barium carbonate and coated with polyethyleneglycol 20000 as liquid phase according to Grob et al.
