Cocaine testing in wastewater: Mixed-mode chromatography in LC/MS

Date: May 9, 2019

Author: Steve Down

Mixed-mode chromatography combined with tandem mass spectrometry has been used for the first time to measure cocaine and its metabolites and pyrolytic products in wastewater, illustrated by the analysis of samples from Spain and Brazil.

Journal Highlight: Mass spectrometric study of acoustically levitated droplet illuminates molecular‐level mechanism of photodynamic therapy for cancer involving lipid oxidation

Date: May 9, 2019

Author: spectroscopyNOW

Field‐induced droplet ionization mass spectrometry combined with acoustic levitation has been used to study the wall‐less oxidation reactions of 18:1 cardiolipin and POPG mediated by singlet oxygen at the air‐water interface of levitated water droplets.

Grenfell's toxic legacy: Deadly dioxins in local soil and dust

Date: Apr 25, 2019

Author: Steve Down

Elevated levels of toxic compounds such as dioxins, PAHs and hydrogen cyanide have been found in soil and an apartment near the site of the Grenfell Tower fire of 2017, posing serious health risks to local people and survivors.

Parkinson's perfume: Sebum biomarkers form diagnostic panel

Date: Apr 10, 2019

Author: Steve Down

The characteristic odour that escapes from the skin of people with Parkinson's disease that could be detected by an especially sensitive individual has now been characterised by scientists in the UK, leading to the possibility of a skin swab test for early detection of the disease.

Tainted tattoo inks: Anaesthetics increase health risk

Date: Mar 12, 2019

Author: Steve Down

An LC/MS method has been designed to identify and measure anaesthetics that have been surreptitiously added to tattoo inks, a practice that could present serious health risks to the recipients.

Deep UV laser ablation: Soft technique leaves peptides and proteins intact

Date: Feb 28, 2019

Author: Steve Down

A gentle ambient laser ablation technique linked with electrospray ionisation mass spectrometry provided spectra of intact peptides, proteins and phospholipids that were identical to conventional electrospray spectra, providing an opportunity for rapid and accurate biomolecule analysis.
