Monitoring, characterizing, and preventing microbial degradation of ignitable liquids on soil
… hydrocarbons such as those found in various ignitable liquids can also serve as a source of carbon to support bacterial growth. This is problematic for fire debris analysis as samples may be stored at room temperature for extended periods before they are analyzed due to case backlog. As a …

Oil Dries: A New Absorbent Material For Collection Of Ignitable Liquids From Semi-Porous Material
<p>Extraction of an ignitable liquid sample from a semi-porous surface such as concrete is especially difficult. For this purpose, two different solid oil dry absorbent materials, Instazorb and MAXXAbsorb, were researched for use of collection of ignitable liquid samples at a fire scene. These oil …

Desarrollo de métodos de caracterización de activadores en incendios
… or accidentally). In arson, accelerants such as ignitable liquids are commonly used to initiate or accelerate a fire. The detection of ignitable liquid residues at fire scenes is therefore a key step in fire investigations. The most widely used analytical technique for the analysis of accelerants …

Quantitative Assessment of the effects of Microbial Degradation of a Simple Hydrocarbon Mixture
Ignitable liquids consist of either a single organic compound or a complex organic mixture. In regards to fire debris analysis, the analyst is responsible for determining if an ignitable liquid residue is present. However, when extracted from soil-containing fire debris evidence, chemical …

Using multivariate statistical procedures to identify ignitable liquid residues in the presence of interferences
… debris. In this approach, the chromatogram of an ignitable liquid residue (ILR) extracted from the debris is visually compared to chromatograms of neat liquids in a reference collection. However, the association of the ILR to the neat liquid can be affected by factors such as matrix interferences, …

Absorbent Household Materials For The Collection Of Ignitable Liquid Residues From Surfaces Of Varying Porosity
<p>Ignitable liquids (ILs) are used as accelerants to burn items at a faster rate and the presence of an IL indicates that arson has occurred. Upon arrival to an arson scene, fire investigators access the scene and collect substrates containing ILs. The substrates, such as concrete and wood, are …

An Evaluation of Tape for the Collection of Ignitable Liquid Residues from Non-Porous and Porous Surfaces
Ignitable liquids are flammable mixtures used to accelerate a fire. ILs are composed of a broad range of hydrocarbons and include commonly encountered materials such as gasoline, diesel, and kerosene. In the event of a suspected arson, ILR may be found within the pores of materials at the crime …

Colorimetric sensor arrays with a pre-oxidation method for gaseous analytes
… of both gases/vapors and analytes in aqueous liquids. These colorimetric sensor arrays, however, are extremely effective for detecting reactive species, they do not exhibit high sensitivity to less-reactive vapors. Common volatile organic compounds (e.g., aromatic hydrocarbons, chlorocarbons) …

Detection of gasoline from internal tissues for use in determining victim status at the time of a fire
… areas as they allow for better retention of the ignitable liquids. The evidence typically collected includes carpets, cardboards, soils, cloths and other items that have not been impinged by flame such as beneath baseboards. These samples are analyzed for the presence of ignitable liquid residues …
