• Resumen

  • Static headspace analysis of accelerants from suspected arsons is accomplished by placing an arson sample in a sealed container with a carbon strip suspended above the sample. The sample is heated, cooled to room temperature, and then the organic components are extracted from the carbon strip with carbon disulfide followed by gas chromatography analysis. A locally available carbon filter has successfully been substituted for the Albrayco carbon strip commonly used in arson analysis. This substitution has resulted in a cost reduction from $1.50 to 1.5¢ per sample.
