Reliable, sensitive, and selective analysis of chemically diverse volatile organic compounds (VOCs) and inorganic gases cannot be achieved using traditional chromatographic techniques unless multiple analyses are invoked. A more recent analytical technique – Selected Ion Flow Tube Mass Spectrometry (SIFT-MS)1,2 – overcomes this limitation by eliminating chromatography and using highly controlled chemical ionization to achieve broad-spectrum, direct analysis of air and headspace.
Direct analysis using selected ion flow tube mass spectrometry (SIFT-MS) enables real time monitoring of formaldehyde to subpart-per-billion concentrations, and simplifies and accelerates both sampling and analysis, providing 25-fold throughput enhancements.
The use of biofuels as an accelerant in arson attacks has increased over recent years. This can be challenging for the Forensic Chemist tasked with analysing the debris to determine the location and nature of the fire.
