(Practice)Standard Practice for Separation of Ignitable Liquid Residues from Fire Debris Samples by Solvent Extraction
Standard Practice for Separation of Ignitable Liquid Residues from Fire Debris Samples by Solvent Extraction
SIGNIFICANCE AND USE
This practice is useful for preparing extracts from fire debris for later analysis by gas chromatography-mass spectrometry (GC/MS).
This is a very sensitive separation procedure, capable of isolating quantities smaller than 1 μL of ignitable liquid residue from a sample.
This practice is particularly useful when the potential for fractionation during separation must be reduced, as when attempting to distinguish between various grades of fuel oil.
This practice is particularly useful for the extraction of nonporous surfaces such as glass, or the interior of burned containers. It is also particularly well suited to the extraction of materials from very small samples.
This practice can be hampered by coincident extraction of interfering compounds present in the fire debris samples.
This practice may not be useful for the extraction of some extremely volatile ignitable liquids, which may evaporate during the concentration step.
This is a destructive technique. Whenever possible, this technique should only be used when a representative portion of the sample can be reserved for reanalysis. Those portions of the sample subjected to this procedure may not be suitable for resampling. If destruction of the sample is an issue, consider using passive headspace concentration as described in Practice E1412.
SCOPE
1.1 This practice covers the procedure for removing small quantities of ignitable liquid residue from samples of fire debris using solvent to extract the residue.
1.2 This practice is suitable for successfully extracting ignitable liquid residues over the entire range of concentrations.
1.3 Alternate separation and concentration procedures are listed in the referenced documents (Practices E1388, E1412, E1413, and E2154).
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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. For a specific hazard statement, see 5.5.
