A laser is focused on the surface of a sample; it ablates a small amount of sample and a micro-plasma is formed on top of the sample, where the neutral and ionic species are excited to a higher energy state.…”

“…The same laser performs micro sampling and acts as an agent that breaks down material to feed the ICP, while it acts as a plasma-forming agent in LIBS. In this way the two techniques, ICP-MS and LIBS can be performed simultaneously on the same sample 41 . The laser parameters like the laser energy, the laser frequency, the laser spot-size, and the scanning speed have to be optimized in a way that it favors both the techniques.…”

Mass spectrometry (MS) is a technique widely used in forensic science for the identification of molecular or elemental composition of submitted evidence. Relatively small, volatile, nonpolar molecules, such as ignitable liquids and some drugs, can be analyzed with electron and chemical ionization (CI) coupled with single‐stage mass analyzers that provide molecular weight and structural information. Nonvolatile and polar molecules such as other drugs, poisons, and/or their metabolites can be identified using electrospray or related soft ionization techniques. The use of tandem MS with these compounds allows structure elucidation and provides excellent screening and quantitative results. Ambient ionization sources allow sampling directly from a surface with minimal sample preparation required. Elemental profiles also provide reliable methods for distinguishing between forensic samples. This article aims to provide an overview of the MS instrumentation, techniques, and applications within the field of forensic science.

The focus of this work is a comprehensive overview of analytical techniques for elemental and isotopic analyses applied in forensic science (i.e. linking crime scene evidence to a crime by applying analytical techniques). The article provides a short description of the spectroscopic techniques and an overview of selected applications. In addition to general forensics, applications in nuclear forensics, environmental forensics, and food forensics are covered. Selected applications are linked to reviews and selected publications, which should allow for an overview of the current approaches in forensic analytical chemistry. This is an update article of its first version published in 2014 by Prohaska and Draxler. 1
