Protein hydrolysates are now routinely analysed by ion exchange chromatography (1) but a complete determination takes at least 3 hours. In addition, the automated amino acid analyzers now used are expensive and have limited application to other problems. Gas chromatography (g.1.c.) offers potential

Bile acids, such as cholic, chenodeoxycholic, deoxycholic, lithocholic and ursodeoxycholic acids, were allowed to react with hexafluoroisopropanol and trifiuoroacetic anhydride at 37" for 30 min. The resulting derivatives were gas chromatographed on QF-1, with flame ionization detection, and were id

In investigating the kinetics of the transesterification reactions of dimethyl terephthalatc with ethylene glycol, determination of the product distribution isachieved by gas-liquid chromatographic analysis. Silylation of hydroxyl groups prior to chromatography was found to be necessary in obtaining
