A charcoal sampling method and a gas chromatographic analytical procedure for carbon disulfide.

Research is reported concerning an acceptable method for sampling and analyzing samples for carbon disulfide. Test atmospheres of carbon disulfide were generated dynamically using the syringe injection method, ant the theoretical concetnration verified by a liquid absorbent, colorimetric method. The CS2 was adsorbed on charcoal tubes, eluted with benzene, and quantitated with a gas chromatography equipped with a sulfer flame photometric detector. The results compared with the colorimetris analysis. The sensitivity of this method is 1 mug on a charcoal tube. The charcoal tubes were also tested for breakthrough volumes, holding power vs time, and the effect of air transport and temperature cycles.
