• Description:
  Comparisons were made between aqueous headspace standards and SUMMA canister standards using a portable gas chromatograph (GC), and between SUMMA canister analytical results from the portable GC and GC/mass spectrometry (MS). According to results of both the theoretical and experimental studies, the aqueous headspace standard is a suitable volatile organic compound (VOC) sta ndard for ambient air field screening analysis. The field screening headspace standard was easy to prepare with materials that were readily available in any laboratory. Little time for preparation was required and the cost was minimal. Canister standards were highly accurate for most of the VOCs and reflected real concentrations of the VOCs inside. The canisters were easily stored and transported, and were reusable. The VOC concentration in canisters remained stable over the normal field condition ambient temperature from -20 to 40 degrees-C. The time dependent canister stability tests showed that canister VOC standards have long term stability. Compared to aqueous headspace standards, canister standards were relatively expensive. This method would be suitable only for those laboratories which have a canister analysis set up.
