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
