Association and discrimination of diesel fuels using chemometric procedures for forensic arson investigations. - 160 p.

Adviser: Ruth Waddell Smith.

Thesis (M.S.)--Michigan State University, 2008.

The identification of an ignitable liquid in fire debris is indicative of an intentional fire and hence, is significant evidence in arson investigations. Currently, gas chromatography-mass spectrometry (GC-MS) is the conventional analytical technique used for the identification of ignitable liquids through chromatographic pattern matching. Chemometric procedures such as Pearson Product Moment Correlation (PPMC) coefficients and Principal Components Analysis (PCA) provide a more objective method to statistically associate and discriminate burned and unburned diesel fuels based on chemical composition in both the total ion chromatogram (TIC), as well as extracted ion profiles (EIP) corresponding to characteristic compound classes in the diesel samples. Data pre-treatment options, such as retention time alignment and area normalization, were also investigated in order to determine their effects on the chemometric results.

520 $a The identification of an ignitable liquid in fire debris is indicative of an intentional fire and hence, is significant evidence in arson investigations. Currently, gas chromatography-mass spectrometry (GC-MS) is the conventional analytical technique used for the identification of ignitable liquids through chromatographic pattern matching. Chemometric procedures such as Pearson Product Moment Correlation (PPMC) coefficients and Principal Components Analysis (PCA) provide a more objective method to statistically associate and discriminate burned and unburned diesel fuels based on chemical composition in both the total ion chromatogram (TIC), as well as extracted ion profiles (EIP) corresponding to characteristic compound classes in the diesel samples. Data pre-treatment options, such as retention time alignment and area normalization, were also investigated in order to determine their effects on the chemometric results.
520 $a The association and discrimination of burned and unburned diesels was also examined. Diesels were spiked onto different matrices commonly found in the home (cotton cloth, magazine, and carpet) and burned in order to simulate arson conditions. The burned diesels were extracted using solvent extraction procedure and analyzed by GC-MS. The data generated from the burnings was compiled into the same set as the data generated from the neat diesels so that PPMC and PCA could be applied to the entire data set. The potential for the association and discrimination of the burned diesels using these procedures was investigated.
