=== MEASUREMENT OF PERSONAL EXPOSURE TO 1,1,1-TRICHLOROETHANE AND TRICHLOROETHYLENE USING AN INEXPENSIVE SAMPLING DEVICE AND BATTERY-OPERATED PUMP === SIMMONS, J.H., MOSS, I.M., 1973. MEASUREMENT OF PERSONAL EXPOSURE TO 1,1,1-TRICHLOROETHANE AND TRICHLOROETHYLENE USING AN INEXPENSIVE SAMPLING DEVICE AND BATTERY-OPERATED PUMP. The Annals of Occupational Hygiene 16, 47β49. https://doi.org/10.1093/annhyg/16.1.47 [https://doi.org/10.1093/annhyg/16.1.47] Abstract The vapours of trichloroethylene and/or 1,1,1-trichloroethane are trapped on silica gel contained in a robust sampling tube made from a galvanized iron pipe connector and Simplifix couplings. Air from the worker's breathing zone is sucked through the tube by a battery operated personal sampling pump, sampler and pump being held on a harness fitted to the worker. Adsorbed solvent is eluted with methanol and estimated by gas chromatography using Chromosorb 101 as stationary phase. Mean exposure over a shift can be determined and related to parallel physiological measurements. Own Comments: * 1973 * Personal sampling tube was devised and tested with exposure to Tris
