Viability of using SUMMA polished canisters for the collection and storage of parts per billion by volume level volatile organics
Article Abstract:
SUMMA polished canisters are practical collection and storage devices for a wide range of compound classes such as alkanes, alkenes, alkynes, aldehydes, ketones, alcohols, aromatics and sulfur-containing compounds. The accuracy, precision and storage stability of canisters were tested using 194 volatile organic compounds generated in humidified ambient air and collected in SUMMA polished canisters. Eighty-six percent, or 168 of the 194 compounds studied, appear to be agree with the canister medium.

Determination of polychlorinated terphenyls in aquatic biota and sediment with gas chromatography/mass spectrometry using negative chemical ionization
Article Abstract:
The presence of polychlorinated terphenyls (PCT) in aquatic biota and sediments was investigated by gas chromatography/mass spectrometry using negative chemical ionization. The results showed that total PCT concentrations ranged from 0.28 micrograms/kg of wet weight in biota. Hexachloroterphenyls were the major group. In sediments, PCT concentrations ranged from 22 to 100 micrograms/kg of wet weight.

Compound detection and concentration estimation by open-path Fourier transforminfrared spectrometry and canisters under controlled field conditions
Article Abstract:
The quantitative and qualitative capabilities of three Fourier transform infrared spectrometer systems (FTIR) were assessed. The centerline of an artificially generated volatile organic compound plume were subjected to 15 releases from the spectrometers. Results were statistically tested. Excellent aliphatic halogenated compounds identification was demonstrated by the three FTIR participants.
