We used high-resolution glass capillary columns to study the trimethylsilyl derivatives of some acidic metabolites found in pooled urine specimens form control and postpartum subjects. About 30 compounds were identified by gas chromatography-mass spectrometry-computer techniques. In general, open tubular capillary columns effect better resolution of trimethylsilyl derivatives of organic acids than do conventional packed columns. GESE-30 proved to be a good general-purpose stationary phase, whereas OV-17 offered certain advantages in resolving aromatic acid components.
我们使用高分辨率玻璃毛细管柱研究了从对照受试者和产后受试者的混合尿液标本中发现的一些酸性代谢物的三甲基硅烷基衍生物。通过气相色谱 - 质谱 - 计算机技术鉴定出约30种化合物。一般来说，开管毛细管柱对有机酸三甲基硅烷基衍生物的分离效果比传统填充柱更好。GESE - 30被证明是一种良好的通用固定相，而OV - 17在分离芳香酸成分方面具有一定优势。
