Current fire debris analysis procedure involves using the chromatographic patterns of total ion chromatograms, extracted ion chromatograms, and target compound analysis to identify an ignitable liquid according to the American Society for Testing and Materials (ASTM) E 1618 standard method. Classifying the ignitable liquid is accomplished by a visual comparison of chromatographic data obtained from any extracted ignitable liquid residue in the debris to the chromatograms of ignitable liquids in a database, i.e. by visual pattern recognition. Pattern recognition proves

Identification of ignitable liquid residues in the presence of background interferences, especially those arising from pyrolysis processes, is a major challenge for the fire debris analyst. The proposed research will lead to a mathematical model that allows for the detection of an ignitable liquid in a fire debris sample and the classification of the ignitable liquid according to the ASTM E1618 classification scheme. The research will examine the influence of substrate pyrolysis and non-pyrolysis interferences on: (1) probability of correct prediction

The study of fire debris analysis is vital to the function of all fire investigations, and, as such, Fire Debris Analysis is an essential resource for fire investigators. The present methods of analysis include the use of gas chromatography and gas chromatography-mass spectrometry, techniques which are well established and used by crime laboratories throughout the world. However, despite their universality, this is the first comprehensive resource that addresses their application to fire debris analysis. Fire Debris Analysis covers topics such

The fire debris analyst is often faced with the complex problem of identifying ignitable liquid residues in the presence of products produced from pyrolysis and incomplete combustion of common building and furnishing materials. The purpose of this research is to investigate a modified destructive distillation methodology provided by the Florida Bureau of Forensic Fire and Explosive Analysis to produce interfering product chromatographic patterns similar to those observed in fire debris case work. The volatile products generated during heating of substrate

The application of comprehensive two-dimensional gas chromatography (GC × GC) for the forensic analysis of ignitable liquids in fire debris is reported. GC × GC is a high resolution, multidimensional gas chromatographic method in which each component of a complex mixture is subjected to two independent chromatographic separations. The high resolving power of GC × GC can separate hundreds of chemical components from a complex fire debris extract. The GC × GC chromatogram is a multicolor plot of two-dimensional retention time and detector signal

The goal of the research conducted under this grant was to develop a chemometric method of data analysis that would facilitate the identification of GC-MS patterns associated with ignitable liquid classes, as designated under ASTM E 1618-10. The objective of the research was to develop a data analysis method that would classify ignitable liquid residue in the presence of background interferences found in fire debris. Pattern recognition and classification methods available at the onset of this research did not explicitly

Current methods in ignitable liquid identification and classification from fire debris rely on pattern recognition of ignitable liquids in total ion chromatograms, extracted ion profiles, and target compound comparisons, as described in American Standards for Testing and Materials E1618-10. The total ion spectra method takes advantage of the reproducibility among sample spectra from the same American Society for Testing and Materials class. It is a method that is independent of the chromatographic conditions that affect retention times of target

Some items commonly submitted as evidence in fire investigations contain inherent interferences that pose challenges during data acquisition, analysis and interpretation. One common type of interference is inherent ignitable liquids, or ignitable liquids that are inherently part of the item due to manufacture. Petroleum-based solvents may be introduced to shoes during the manufacturing process. The challenge in data interpretation arises from the fact that some shoes contain the same types of ignitable liquids that are used as accelerants during the

Arson is one of the most challenging crimes for forensic scientists to investigate. The variability in the composition of ignitable liquids, including changes in chemical composition during and after the fire, and the presence of pyrolysis products generated from burning substrates yields a very complex mixture of volatile compounds in samples of fire debris. Headspace extraction of debris samples followed by gas chromatography-mass spectrometry (GC-MS) is the most common approach for fire investigation. For many laboratories, data interpretation is the

Identification of ignitable liquids in fire debris samples is typically conducted via comparison of total ion chromatograms (TICs) of such samples to reference collections containing chromatograms of common liquids. Due to the extent of liquid evaporation in fires, reference collections often contain TICs of ignitable liquids that have been experimentally evaporated to various levels; however, such evaporations can be time intensive. A kinetic model was developed to predict evaporation rate constants of compounds as a function of GC retention index.

It is rare to find a book published for forensic examiners who perfoim fire debris analysis. This book addresses two issues for those involved in the identification of ignitable liquids recovered from fire debris; first, the increased availability of "speciality solvents" which do not fall into the five main categories of more familiar and easily recognizable ignitable liquids and, second, the increased use of mass spectrometry for the identification of ignitable liquids.

Fire debris analysis currently relies on visual pattern recognition of the total ion chromatograms, extracted ion profiles, and target compound chromatograms to identify the presence of an ignitable liquid. This procedure is described in the ASTM International E1618-10 standard method. For large data sets, this methodology can be time consuming and is a subjective method, the accuracy of which is dependent upon the skill and experience of the analyst. This research aimed to develop an automated classification method for
