Formerly, it was impossible to determine trace amounts of organic mercury compounds and to clarify their chemical forms. The author, utilizing a gas chromatograph with an electron capture detector, successfully performed ultra-trace determinations of alkyl and phenyl mercury. In alkyl mercury analysis DEGS and 1.4-BDS were used as stationary phases, packed in glass on-columns. In phenyl mercury analysis 5% DEGS was used with on-column injection techniques. After scrutinizing various conditions, a detection limit for methyl mercury chloride was reached at 10- 12g and for phenyl mercury chloride at I0^-11g. Isolation of organic mercury from different materials was performed by separation of organic mercury combined with SH radical in 1N-HCl solution. The solution was then extracted with benzene, and this benzene solution re-extracted with glutathione. After acidification of the resulting solution with HCl, final extraction with benzene was performed. This clean-up method was employed in the identification of organic mercury and was a very useful technique for its extraction.
