气相色谱法测定中药材中的水分含量

The Determination of Water Content in Chinese Traditional Medicine by Gas Chromatography

利用高分子多孔微球为气相色谱固定相,气相色谱外标一点法检测部分干中药材中的微量水含量.

The determination of minim content of water in Chinese traditional medicine was performed by gas chromatography using macromolecule multihole miniball as the stationary phase. The optimum conditions for GC were studied and the quantitative determination of water was accomplished by external standard addition method.
