Standard Practice for Separation of Ignitable Liquid Residues from Fire Debris Samples by Dynamic Headspace Concentration onto an Adsorbent Tube
1.1 This practice describes the procedure for separation of ignitable liquid residues from fire debris samples using dynamic headspace concentration onto an adsorbent tube, with subsequent solvent elution or thermal desorption.
1.2 Dynamic headspace concentration onto an adsorbent tube takes place from a closed, rigid sample container (typically a metal can), using a source of dry inert gas or a vacuum system.
1.3 Both positive and negative applied pressure systems for dynamic headspace concentration onto an adsorbent tube are illustrated and described.
1.4 This practice is suitable for preparing extracts from fire debris samples containing a range of volumes (µL to mL) of ignitable liquid residues, with sufficient recovery for subsequent qualitative analysis (1).2
1.5 Alternative headspace concentration methods are listed in Section 2 (see Practices E1388, E1412, E3189, and E2154).
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 This standard cannot replace knowledge, skills, or abilities acquired through education, training, and experience (Practice E2917) and is to be used in conjunction with professional judgment by individuals with such discipline-specific knowledge, skills, and abilities.
1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
