Significance and Use | ||||||||||||||||
This practice is useful for preparing extracts from fire debris for later analysis by gas chromatography, GC/MS, or GC/IR. This is a very sensitive separation procedure, capable of isolating quantities smaller than 1/10 μL of ignitable liquid residue from a sample. |

1. Scope | ||||||||||||||||
1.1 This practice covers the procedure for removing small quantities of ignitable liquid residue from samples of fire debris using an adsorbent material to extract the residue from the static headspace above the sample, then eluting the adsorbent with a solvent. 1.2 While this practice is suitable for successfully extracting ignitable liquid residues over the entire range of concentration, the headspace concentration methods are best used when a high level of sensitivity is required due to a very low concentration of ignitable liquid residues in the sample. 1.2.1 Unlike other methods of separation and concentration, this practice is essentially nondestructive. 1.3 Alternate separation and concentration procedures are listed in the referenced documents. (see Practices E 1385, E 1386, E 1388, and E 1413). 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. |
