1.1 This practice describes the procedure for separation of ignitable liquid residues from fire debris samples using static headspace concentration onto an adsorbent tube, for subsequent solvent elution or thermal desorption. 1.2 Static headspace concentration onto an adsorbent tube takes place from a closed sample container (typically a jar, can, or bag) using a syringe or pump. 1.3 Static headspace concentration systems for adsorption onto an adsorbent tube are illustrated and described. 1.4 This practice is suitable for extracting ignitable liquid residues over a range of concentrations (L/L to mL/L). 1.5 Alternative headspace concentration methods are listed in Section 2 (see Practices E1388, E1412, E1413, and E2154). 1.6 This practice is intended to be used by individuals with discipline-specific knowledge, skills, and abilities acquired through education, training, and experience. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
