#ALT# Forensics at your Fingertips: Moving Towards On-Scene Identification?

Forensic science is based on the idea that every interaction leaves a trace, so every crime leaves some evidence of the perpetrator. As a result, identifying and analyzing both known and unknown substances is a vital part of forensic science. In this way, justice often depends on reliable analytical methods and techniques. The latest advances in analytical chemistry now promise a new era of forensic science.

Join Pittcon in Chicago from the 1st -5th March at McCormick Place for the the latest research, instrumentation, techniques, and collaboration.

In order to accurately quantify the concentration of trace analytes within a complex mixture, appropriate sample preparation is imperative. Some of the most common pretreatment methods that are used prior to analysis by high-performance liquid chromatography (HPLC) or gas chromatography with mass spectrometry (GC-MS) include liquid-liquid extraction (LLE) and solid phase extraction (SPE).

New sweat test could help detect a person’s marijuana-useForensic chemist Jan Halámek is proving that our own perspiration not only gives away how drunk we are – but if we are high, too. The lab has captured the ability to detect a person's marijuana-use based on contents in a small skin secretion that can be taken from fingerprints or any other sweat glands.

A Thin-Film Microextraction Procedure for the Illicit Drug Screening of BiofluidsA team from the University of Waterloo have developed a direct and fast means of quantifying drug levels in beverages and bodily fluids. Using a new analytical setup – dielectric barrier discharge (DBD), combined with high-resolution mass spectrometry – the team achieved an enhanced dynamic range of detection and lower limits of quantitation, compared to the prevailing techniques.
