Evaluation of HAPSITE-ER Peripherals-SPME vs. Headspace
The United States Air Force is examining recapitalization of two peripherals employed with the HAPSITE ER. The Air Combat Command/Surgeon General (ACC/SG) has inquired if Solid Phase Micro Extraction (SPME) analysis is comparable to the results obtained by the headspace sampler (HSS). This study examined the relative performance of the two peripherals and provided data on relevant operational parameters, such as limits of detection, linear range and quantification reliability. Results indicate that HSS is more effective for field use than SPME. Many analytes, specifically semi-volatile organic analytes (SVOAs), could not be detected by SPME sampling at any of the tested concentrations.
