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 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 Class 0 and Class 1 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. Consider using passive headspace concentration as described in Practice E 1412. |

1. Scope | ||||||||||||||||
1.1 This practice covers the procedure for removing small quantities of flammable or combustible liquid residue from samples of fire debris using solvent to extract the residue. 1.2 This practice is suitable for successfully extracting flammable or combustible liquid residues over the entire range of concentrations. 1.3 Alternate separation and concentration procedures are listed in Test Method E1387. 1.4 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 Note 1. |
