Introduction to ASTM E1412
According to ASTM E1412, ignitable liquid residues in tiny amounts can be separated from fire debris samples by employing an adsorbent material to extract the residue from the static headspace above the sample and then eluting the adsorbent with a solvent. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E1412 tests for our clients. Extracts from fire debris can be prepared using this technique for later examination using gas chromatography-mass spectrometry. This extremely sensitive separation technique can isolate the ignitable liquid residue of less than 1 µL from a sample.
ASTM E1412 Test Method
| Charcoal Loading | To absorb ignitable liquid residues, charcoal is added to the sample container in the form of an adsorption package. The container can be heated or left at room temperature. |
| Elution of Charcoal | After removing the charcoal, an appropriate elution solvent is used to elute it. |
ASTM E1412 Test Specimens
| Specimen Detail | Combustible liquid residues from fire rubble samples by extracted from the static headspace above the sample with an adsorbent material |
| Specimen Size | Amounts of ignitable liquid residue from a sample less than 1⁄10 µL |
ASTM E1412 Test Result
In ASTM E1412, ignitable liquid residues are extracted from fire debris samples using a solvent and an adsorbent material. Headspace concentration techniques are especially helpful at low concentrations, though they are effective at all concentration levels as well. For precise detection of trace levels of residues in the sample, these sensitive techniques are perfect.
ASTM E1412 Related Tests
ASTM E1412 is related to tests, including ASTM E1386 for employing solvent extraction methods to separate ignitable liquid remains from fire debris and ASTM E1388 for sampling headspace vapors from fire debris samples.
