Air sampling methods for the determination of aliphatic amine compounds were tested during comprehensive industrial hygiene evaluations conducted in three flexible polyurethane foam manufacturing facilities (SIC-3086). Comparative field sample results were presented for the collection of triethylenediamine (280579) and 2,2'-oxybis(N,N-dimethyl)ethylamine (3033623) (2,2'- oxybis) using Thermosorb/A tubes and acid filled midget impingers. Impinger samples were analyzed by gas chromatography with a nitrogen phosphorous detector in the nitrogen mode. The Thermosorb samples were analyzed after desorption by gas chromatography with thermal energy detection in the nitrogen mode and mass spectrometric confirmation. Five of the eight samples collected on the Thermosorb tubes formed a solid gel upon desorption. The solid material was not adequately identified by either gas chromatography with thermal energy activation or mass spectrometric solid probe analysis. No nitrogen containing compounds were detected in any of the Thermosorb samples. Analysis of the impinger samples revealed at least one of the two compounds in each sample. The highest loads for triethylenediamine and 2,2'-oxybis were 290 and 647 micrograms per sample, respectively. The highest air concentrations of the compounds occurred near the foam crushing units, where employees reported halovision most frequently. The authors conclude that the acid impinger method can provide a complementary technique for determination of certain workplace air amine compounds.
