FIRE DEBRIS ANALYSIS

Flammable liquids such as gasoline and lighter fluid typically contain hundreds of individual chemical components. Our Fire Debris analysis procedure follows ASTM Standards E-1618 and E-1387, which define the protocols for analysis of fire debris via Gas Chromatography-Mass Spectrometry (GC-MS). This is the industry standard for identifying components of flammable liquids in an evidence sample. Many laboratories rely on analysis via gas chromatography pattern recognition. The use of a mass spectrometer as the detector for the gas chromatograph allows the chemist to identify individual components in a flammable liquid sample and improve detection limits.

Our laboratory equipment includes a Thermo-Finnigan GC-MS with an automated sampler, which is recommended by ASTM protocols for fire debris analysis. Positive and negative controls are run with each sample set, insuring reliable, consistent results. Questioned samples are compared to hundreds of known flammable liquid standards run in our laboratory.

Typically, reports are issued within five days of receipt of the samples. However, quality control is essential element of our laboratory services. Our award winning chemists participate in external proficiency testing and all data is technically reviewed before reports are issued.

Samples are stored in a climate controlled secure storage facility. Additionally, computer generated bar-code labels provide positive sample inventory control and sample identification. Replacement sample containers are provided to customers free of charge.
