Sweat diffusion through snow: Canines and trapped humans

Date: May 15, 2016

Author: Steve Down

A GC/MS method with direct immersion SPME has been developed for measuring the diffusion dynamics of human sweat compounds buried under snow, which will help to understand the success rate of search and rescue dogs combing avalanches for victims.

Indoor benzothiazoles: Abundant in air

Date: Apr 15, 2016

Author: Steve Down

All indoor air samples from Albany, New York, that were tested for toxic benzothiazoles proved to be positive, the largest concentrations being found in automobiles, homes and garages.

Journal Highlight: Mass fingerprint analysis of spider mites (Acari) by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry for rapid discrimination

Date: Apr 11, 2016

Author: spectroscopyNOW

Spider mites have been analyzed directly by MALDI-TOFMS, with evolutionarily and morphologically closely related mites showing different mass fingerprints, allowing for their identification.

Illegal drugs in hair: Inadequate washing procedures falsify results

Date: Apr 1, 2016

Author: Steve Down

A mass spectrometric study of the spatial distribution of illicit drugs in hair shows that currently accepted decontamination techniques are inadequate and could lead to misleading conclusions with legal consequences.

Illicit drug screening: Festival goers help wastewater metabolism studies

Date: Mar 16, 2016

Author: Steve Down

European scientists have used an HILIC MS method to analyse urine and urinated soil collected from music festivals to identify the most popular illicit drugs and to determine the stable transformation products in wastewater for future targeting.

The MIDAS touch for TLC: Novel ambient mass spec source

Date: Mar 1, 2016

Author: Steve Down

An ambient ionisation source based on desorption APCI has been developed for the analysis of compounds on surfaces, illustrated by the identification and measurement of different types of compounds separated on TLC plates.

Banknote security: Depth profiling by ambient mass spectrometry

Date: Feb 15, 2016

Author: Steve Down

Counterfeit banknotes can be distinguished from authentic currency by electrospray laser desorption/ionisation mass spectrometry, an ambient technique that allows depth profiles to be produced for enhanced discrimination.
