Ignitable liquids residue (ILR) analysis procedures are publicly available and well documented with American Society for Testing and Materials (ASTM) standard procedures.
Conducting ILR analysis is not difficult; however, it must be conducted with the highest sensitivity and confidence, eliminating the potential for false positives. Chemistry Matters executes chemical analysis of ILRs using very sensitive analytical instrumentation. Our analysis includes multiple redundancies for ILR identification, which exceeds routine ASTM methodologies. This provides results that go beyond simple presence or absence of ILRs.
Chemistry Matters specializes in sample collection for chemical analysis as part of litigation matters. When litigation is involved, special sampling precautions are required to ensure samples are:
- Collected using fully documented and approved techniques
- Thoroughly documented to prove sample integrity
- Kept in legal chain of custody throughout the process
- Preserved properly to prevent degradation
Chemistry Matters helps consult on sampling procedures and design, or can be retained to conduct the sampling for exceptionally sensitive cases.
Chemistry Matters provides the only advanced analysis of organic compounds present in ILRs and matrices from arson investigations.
Using a highly specialized detection technique of two-dimensional gas chromatography, coupled with time-of-flight mass spectrometry (2DGC-TOFMS), Chemistry Matters can offer full fingerprinting of ILRs and identification of all extraneous organic compounds present in arson debris. 2DGC-TOFMS is capable of identifying all organic residues present from the extraction of a fire debris sampling.
The use of 2DGC-TOFMS provides Chemistry Matters with unprecedented identification capabilities that not only helps identify presence or absence of ILRs, but can also be used to identify the source of the ILRs (where it was purchased) if commercial samples are available.
