In this study, a simple method was used for extraction and concentration of trace organic compounds in water, followed by injection using a coiled wire filament and GC–MS analysis. Common semivolatile organic compound contaminants at low parts-per-billion levels were detected in less than 10 min.
Rapid sample preparation using the CUSTODIONâ„¢ solid phase microextraction (SPME) syringe was applied to chemical warfare agents (CWAs), CWA simulants, by-products, and precursors. The samples were analyzed quickly and reliably with a sample-to-sample cycle time of less than 3 min using the GUARDIONâ„¢-7 portable capillary gas chromatograph toroidal ion trap mass spectrometer (GC–TMS).
In this article, methods developed for rapid, automated detection of CWAs and TICs using a low thermal mass capillary gas chromatograph coupled to a toroidal ion trap mass spectrometer (TMS) are presented.
The CUSTODIONâ„¢ SPME Syringes are a series of novel solid phase micro extraction syringes that incorporate Supelco Analytical'sÂ® (Bellefonte, Pennsylvania) SPME fiber technology. The SPME syringes are fabricated with injection-molded components and the device resembles a ball-point pen. The Supelco AnalyticalÂ® SPME fiber assembly is housed inside the syringe.
