GC-MS/MS

Gas Chromatography coupled to Tandem Mass Spectrometry (GC/MS/MS) is used to separate the organic compounds in the mixture (fire debris). This technique is increasingly becoming the analytical tool of choice when analyzing target compounds in very complex matrices. MS/MS is a highly selective mass spectrometric technique, whereby target analytes are detected regardless of the sample matrix or coeluting interferences. In many GC/MS/MS applications the matrix is virtually eliminated. GC/MS/MS is ideal for fire debris analysis and has been used for the analysis of target compounds in various matrices such as complex environmental samples, pesticides in foods, drug metabolites, drug residues in biological fluids and other forensic trace evidence.

GC/MS/MS is a more powerful analytical technique that provides a method for detecting target compounds in complex matrices at trace levels. This method is designed to provide a better analysis for weak, highly weathered or older samples. It is particularly well suited for the detection of gasoline and can be used on any sample. This confirmatory analysis can provide the additional information necessary to determine a positive result, when singular GC/MS analysis fails, if an ignitable liquid is present.
