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.

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.

Journal Highlight: LC/ESI-MS/MS method for determination of salivary eicosapentaenoic acid concentration to arachidonic acid concentration ratio

Date: Feb 8, 2016

Author: spectroscopyNOW

A simple LC/ESI-MS/MS method for measuring the ratio of eicosapentaenoic acid to arachidonic acid in human saliva has been developed to help predict the risk of cardiovascular disease, especially atherosclerosis.

Multidrug abuse in opioid treatment programmes: The emergence of new psychoactive substances

Date: Feb 1, 2016

Author: Steve Down

Scientists in Finland have used LC/MS with a high-resolution mass spectrometer to reveal that many people on opioid drug treatment programmes continue to seek highs by polydrug abuse of traditional drugs as well as new psychoactive substances.

Ambient ionisation sensitivity: Spray dopant improvements in EASI MS

Date: Jan 15, 2016

Author: Steve Down

The introduction of a simple additive to the solution in easy ambient sonic spray ionisation provided 2-4-fold increases in sensitivity, bringing it on a par with desorption electrospray ionisation mass spectrometry.

Candida breath test: GC/MS possibilities

Date: Jan 4, 2016

Author: Steve Down

A breath test based on GC/MS analysis will be a promising way to diagnose oral candidiasis, say scientists in Germany following the in vitro analysis of volatiles released from cultures of four Candida species.
