  • Title: Improved recovery and stability of ethanol in automated headspace analysis.
    Author: Christmore DS, Kelly RC, Doshier LA.
    Journal: J Forensic Sci; 1984 Oct; 29(4):1038-44. PubMed ID: 6502105.
    Abstract:
    Solutions are reported here for two problems in automated headspace gas chromatographic analysis for ethanol. The first is the catalytic oxidation of ethanol by oxyhemoglobin, a process that is limited only by the amount of oxygen in the sealed vessel. This reaction is prevented by the addition of sodium dithionite. The other problem, the lack of a suitable salting-out agent, led to the selection of ammonium sulfate, which improved recovery of ethanol as well as enhancing method precision. A procedure incorporating these improvements is described.
