Biofluid identity: Forensic evidence

Steve Down

Jun 15, 2018

thumbnail image: Biofluid identity Forensic evidence

Human body fluids collected at crime scenes can be classified from their constituent proteins in a single mass spectrometric experiment that can be combined with DNA analysis for suspect identification.

Some of the numerous, but scattered reports on novel laser desorption/ionization strategies have been reviewed with an emphasis on modified sample support substrates and plates and their potential to markedly enhance the utility of LDI‐MS.

A new thermal desorption-GC/MS procedure has been developed by scientists in Germany for the determination of very volatile organic compounds in indoor air, but it must be supplemented by at least two other methods to include the full range of compounds.

For over 20 years, each issue of the Journal of Mass Spectrometry has contained a Special Feature article. These are highly regarded in the mass spectrometry community and extremely popular with researchers around the globe. These features are freely available to the entire mass spec community.

Selected key technologies of the analytical science industry are discussed by Steve Down with reference to burgeoning application areas and the scope for future improvements.

Ion source pressure plays a significant role in the process of ionization and the subsequent ion transmission inside a mass spectrometer. Pressurizing the ion source to a gas pressure greater than atmospheric pressure is a relatively new approach that aims to further improve the performance of atmospheric pressure ionization sources. A brief review on the development of super-atmospheric pressure ion sources, including high-pressure electrospray, field desorption and superheated ESI, and the strategies to...
