Noble gas could protect stroke victims from brain damage

Date: Jan 12, 2017

Author: Ryan De Vooght-Johnson

As well as being a potent anaesthetic, xenon could be used to protect the brain from irreversible damage. A recent study from the US describes a novel way to deliver xenon into the brains of stroke patients, as well as a reliable assay to measure the amount of the gas in the blood – essential for quality control.

Atmospheric pressure MS method gives hope on OPEs

Date: Jan 1, 2017

Author: Ryan De Vooght-Johnson

Although they have previously tended to keep a low profile, organophosphate esters (OPEs) are widespread chemicals, which have become a hot topic in the analytical world due to their potential harmful effects on health and the environment. Researchers from France and the Lebanon have used mass spectrometry with an APCI source to identify some of these compounds, comparing the results with standard EI spectra.

Red light on toxic tobacco leads to class separation in China

Date: Dec 1, 2016

Author: Ryan De Vooght-Johnson

Whether we love or loathe tobacco, we have to accept that analysis of tobacco volatiles is an important topic, both for the industry and medical investigations. Scientists from China Tobacco and Zhejiang University have developed a novel method of isolating volatile components from tobacco, the data from which allowed the grouping of various tobacco samples into three distinct classes, corresponding to ‘fresh’, ‘moderate’ and ‘rich’ styles.

Reconnaissance repertoire readied: scientists prepare for emerging dechlorane flame retardants

Date: Nov 14, 2016

Author: Ryan De Vooght-Johnson

The perfect villain is the one that evades detection. Attempting to thwart the suspect and ill-defined dechlorane pollutants, scientists based in Belgium have fashioned a Time-of-Flight MS assay for analysing these pollutants in human serum.

Blood, sweat and fatty acids

Date: Nov 1, 2016

Author: Ryan De Vooght-Johnson

Sampling fatty acids? No sweat! In fact, do…a new non-invasive method of sampling fatty acid methyl esters using filter paper to collect sweat could simplify the diagnosis of disrupted lipid metabolism.

Not tarred with the same brush: Study attempts to define the varied molecular makeup of coal tars

Date: Oct 15, 2016

Author: Ryan De Vooght-Johnson

Mother Nature’s fruits are certainly not made under quality controls or standard operating procedures. If we are to use the coals lurking amidst her underbelly, we must live with the vast differences in their phenolic makeup. Could their molecular stratification be a successful coping mechanism?
