A sampling and analytical method for ethylene glycol in air.
Anal Lett 1981Jul; 14(12):959-976
A sampling and analytical method for ethylene-glycol (107211) in air was presented. The sampler was developed for use by workers handling ethylene-glycol industrially. Samples were analyzed with standards. When tested against known concentrations of ethylene- glycol the useful range was approximately 10 to 1000 micrograms per milliliter of solution, when 1 microliter aliquots of solution were injected into the gas chromatograph. Vapor in air concentrations, ranging from 4.2 to 327 milligrams per cubic meter for 3 liter air samples collected during 15 minute periods, were measured. Ethylene- glycol was found to evaporate from the filter during air sampling at 25 degrees C and enter the silica gel tube. If no evaporation occurred from the filter, the lower quantitation limit for ethylene- glycol aerosol in a 3 liter air sample was determined to be 3.3 milligrams per cubic meter. The authors suggest that this device is suitable for use as a personal air sampler for industrial workers and is more convenient than cumbersome bubblers and impingers containing liquids.
