Determination of Sulfur Amino Acids, Glutathione, and Related Aminothiols in Biological Samples by Gas Chromatography with Flame Photometric Detection

. Although GC method based on the preparation of N-heptafluorobutyryl isobutyl or ethyl esters (8 ) is selective and sensitive by flame photometric detection (FPD), this method is not applied to the analysis of biological samples. As the HPLC methods

各种色谱的主要影响因素

：梯度越平缓，分辨率越高，但同时样品越稀。c、流速：影响不大。三、疏水作用色谱： a、疏水凝胶本身的性质： 基架：Sepharose FF 取代基疏水性：Phenyl苯基、Octyl正辛烷基、Butyl正丁基、Ethyl乙基、Iso异丙基均不相同，选择性也不同。 相同的取代基，不同的取代程度：如Phenyl Sepharose 6 FF（Low sub）与Phenyl Sepharose 6 FF（High sub）疏水性不同，选择性也不同。 b、盐类： 一般常使用硫酸铵、硫酸
