At LCS Laboratory Inc., we’re advancing the science behind fire scene analysis. Our latest service expands upon ASTM E2154 methodology to offer not just detection—but accurate quantification—of ignitable liquids in fire debris. Purpose-built for forensic and insurance applications, this updated approach gives fire investigators sharper tools to distinguish between naturally occurring vapours and deliberately introduced accelerants.
Why Accurate Quantification Matters
Pinpointing the presence of ignitable liquids—like gasoline, diesel, kerosene, or lighter fluids—is critical when determining the cause and origin of a fire. Traditional qualitative tests may flag these substances as “present” or “absent,” but quantifying vapour concentrations elevates the evidence: It helps investigators assess whether residual compounds are meaningful or merely background noise from building materials or smoke condensates.
What Sets Our Method Apart
Following the ASTM E2154 standard, our laboratory accepts soil or debris samples delivered in a labelled 32 oz (1 L) mason jar, accompanied by a request-for-analysis form. Each jar is heated to 70°C, allowing headspace vapours to collect. We extract and analyse these vapours using gas chromatography, identifying both the chemical composition and concentrations of the ignitable compounds present.
The result? A reliable, data-driven classification that reveals which compound is most likely to have acted as an accelerant.
Clarity in Interpretation
Here’s what makes our reporting exceptional: Instead of a basic “Detected/Not Detected” format, our reports provide a clear quantitative profile of the sample. For example:
Ethanol – 75 mg/m³
Acetone – 2978 mg/m³
Petroleum Hydrocarbons – < 50 mg/m3
With this level of detail, forensic consultants can quickly deduce that acetone is not only present—it dominates the headspace profile, identifying it as a likely accelerant. This kind of clarity strengthens your fire scene narrative and provides solid scientific footing for expert testimony or insurance assessments.
