Rapid Field Detection of Chemical Warfare Agents, Simulants, By-Products, and Precursors Using Solid Phase Microextraction and Portable GC-TMS

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).

Extraction and Identification of Volatile Organic Compounds from Water in 70 s using SPME and a Hand Portable GC-TMS

The CUSTODIONâ„¢ solid phase microextraction (SPME) syringe was used to rapidly sample and concentrate volatile organic compounds (VOCs) from water in 5 s. The VOCs were analyzed quickly and reliably in approximately 70 s using the GUARDIONâ„¢ -7 portable capillary gas chromatograph toroidal ion trap mass spectrometer (GC-TMS).

CUSTODION ™ SPME Syringe for Rapid Sample Collection and Sample Preparation of Drinking Water for the GC–MS Determination of Trihalomethanes

The CUSTODION™ SPME Syringes are a series of novel solid phase micro extraction syringes that incorporate Supelco Analytical's® (Bellefonte, Pennsylvania) SPME fiber technology. The SPME syringes are fabricated with injection-molded components and the device resembles a ball-point pen. The Supelco Analytical® SPME fiber assembly is housed inside the syringe.
