摘要: Investigation of several column packing materials for the gas-liquid chromatographic analysis vitamin D as trimethylsilyl (TMS) derivatives showed that 4% OV-225 on High Performance Chromosorb W, 100-120 mesh, was most suitable. The TMS were found to be unstable, but adequate reproducibility achieved, using cholestane internal standard, by standardizing time between silylation and injection.
