  Abstract:

  In cases of death by inert gas asphyxiation, it can be difficult   to obtain toxicological evidence supporting assignment of a cause   of death. Because of its low mass and high diffusivity, and its   common use as a carrier gas, helium presents a particular   challenge in this respect. We describe a rapid and simple gas   chromatography– thermal conductivity detection method to   qualitatively screen a variety of postmortem biological specimens   for the presence of helium. Application of this method is   demonstrated with three case examples, encompassing an array of   different biological matrices.
