Field portable gas chromatography-mass spectrometry, GC-MS, have been established as the ‘gold standard’ of chemical identification and quantification for chemical threats however several chemical warfare agents have been shown to evade required detection limits. This work demonstrates the derivatization of O-ethyl S-(2-diisopropylaminoethyl) methy...

Environmental contextQuantitative field-based sampling of airborne volatile organics continues to be a challenge because of the absence of laboratory supplies and facilities. Approaches are required to overcome poor data arising from difficulties with calibration of fielded instruments. This method normalises responses across portable thermal desor...

The HAPSITE-ER-TD (Hazardous Air Pollutants on Site Extended Range HAPSITE-ER) portable gas chromatograph–mass spectrometer (GC–MS) combines the sensitivity of a thermal desorption (TD) GC–MS with the advantages of field-portable instrumentation. Though previous iterations of the HAPSITE have been extensively evaluated in the literature, performanc...

SR-147-05 Removal of Chromium Background from PVC Filters for Air and Wipe Testing Objective: OSHA Methods ID-103 and ID-215 and NIOSH Method 7605 use PVC filters for swipe analysis. Air collection also utilizes the same filters. Over several years, US Air Force and others have tracked the background of hexavalent chromium from field blanks. The o...

Arsine poisoning is a well-recognized phenomenon generally associated with the smelting and refining of metals. However, acute episodes of arsine poisoning do occur in environments unrelated to metal processing and often go unrecognized. The incident described herein, which deals with artists working on the restoration of a famous painting, illustr...
