Headspace-trap gas chromatography-mass spectrometry for determination of sulphur mustard and related compounds in soil
Røen, Bent Tore; Tørnes, John Aasulf; Lundanes, Elsa; Unneberg, Erik (2010)Methods for trace determination of sulphur mustard (HD) and some related cyclic sulphur compounds in soil samples have been developed using headspace-trap in combination with gas chromatography-mass spectrometry (GC-MS). ... -
Identification and quantification by GC-MS of Sulphur mustard and related compounds after long time storage in sea water
Opstad, Aase Mari; Tørnes, John Aasulf (2004)Sulphur mustard in sea water undergoes decomposition to different products over time. After two weeks mustard gas is not detected in the sea water nor in the sediment. Ten decomposition products were identified in sea ... -
Identification of complexes formed between sulphur mustards and arsenic-containing chemical warfare agents
Rantanen, Noora-Kaisa; Ljønes, Marita; Heikkinen, Johannes S; Tørnes, John Aasulf; Kjellberg, Matti A.; Hakulinen, Hanna (2024-10-22)Large quantities of toxic chemical warfare material, such as mixtures of sulphur mustard (HD) and arsenic-containing chemical warfare agents (As-CWAs) have been submerged in the Baltic Sea region after World War II. Little ... -
Integration of chemical and radiological sensors in a tactical network
Tørnes, John Aasulf; Larsen, Erlend (2014-09-01)The Chemical and Radiological (CR) sensors in the Norwegian Armed Forces today are stand-alone units giving alarms locally to the personnel in close proximity to the sensor. Other troops are alerted through the chain of ... -
