Carbon disulfide (CS/sub 2/) in natural waters is determined at the picomolar level by a combination of preconcentration on Carbosieve G and gas chromatography with a flame photometric detector. The volatile carbon disulfide is stripped out of up to 1.8 L of sample by a nitrogen gas stream and preconcentrated on a Carbosieve adsorption tube. This tube is then attached to the gas chromatograph/flame photometric detector system and heated to desorb CS/sub 2/, which is collected in a liquid-nitrogen-cooled trap, released by heating the cold trap, separated on a Chromosil 330 column, and detected by a flame photometric detector. The CS/sub 2/ peak is recorded and integrated electronically. The detection limit is ca. 1 pmol L/sup -1/ CS/sub 2/. The analytical precision is 9%. Results of analyses of natural water samples are presented.
