TLDR
In this article, a non-separative analytical method based on HS-MS eNose (headspace mass spectrometry electronic nose) in combination with chemometric tools, including hierarchical cluster analysis and linear discriminant analysis, has been used to detect and classify ignitable liquid residues in fire debris into the classes defined by the ASTM E1618 standard method.About:

Novel method based on ion mobility spectrometry sum spectrum for the characterization of ignitable liquids in fire debris
TL;DR: The proposed method would be based on ion mobility spectrometry sum spectrum (IMSSS) from headspace analysis, in combination with pattern recognition tools (Linear Discriminant Analysis, LDA) and 100% of fire debris samples were correctly classified for presence/absence and type of IL.

Effects of Fire Suppression Agents and Weathering in the Analysis of Fire Debris by HS-MS eNose
Barbara Falatová,Marta Ferreiro-González,Carlos Martín-Alberca,Danica Kačíková,Štefan Galla,Miguel Palma,Carmelo García Barroso +6 more
TL;DR: Although the suppression systems affect the mass spectra, the HS-MS eNose in combination with suitable pattern recognition chemometric tools, such as linear discriminant analysis, is able to identify the presence of gasoline in any of the studied situations.

Strategies for qualitative and quantitative analyses with mass spectrometry-based electronic noses
José Luis Pérez Pavón,Miguel del Nogal Sánchez,Carmelo García Pinto,Ma Esther Fernández Laespada,Bernardo Moreno Cordero,Armando Guerrero Peña +5 more
TL;DR: The present article reviews the main applications of electronic noses based on mass spectrometry in the environmental field and compares and contrast four strategies to correct signal drift: internal normalization; internal standardization; gas standard addition; and, calibration transfer.
Journal ArticleDOI
Analytical tools for the analysis of fire debris. A review: 2008-2015.
TL;DR: This review critically outlines the most up-to-date and suitable tools for the analysis and interpretation of fire debris evidence and provides relevant knowledge on the distortion effects of the ignitable liquid chemical fingerprints, which have to be considered during interpretation of results.

Covariance Mapping in the Analysis of Ignitable Liquids by Gas Chromatography/Mass Spectrometry
TL;DR: The covariance matrix computed from the retention time-ion abundance data matrix from gas chromatography/mass spectrometry analysis of ignitable liquids is shown to be a useful tool for automated identification of ignitability liquids in a database.

Fast analytical methodology based on mass spectrometry for the determination of volatile biomarkers in saliva.
TL;DR: The method was applied to the determination of biomarkers in 28 saliva samples: 24 of them were from healthy volunteers, and the others were from patients with different types of illness (including different kinds of cancer).

The influence of the type of accelerant, type of burned material, time of burning and availability of air on the possibility of detection of accelerants traces.
TL;DR: Investigation of how different factors influence the possibility of identification of accelerant traces in conditions that are as similar as possible to those of real fires shows that the type of burned material has the greatest influence.
