Surgical mass spec: Intelligent knife finds tumour margins in real time

Date: Aug 1, 2013

Author: Steve Down

A new surgical device known as the iKnife will help surgeons to remove every part of a tumour by analysing the smoke emitted during electrosurgery in real time using an online mass spectrometer.

Conquering the nerve gases: High-resolution mass spectrometry of chemical warfare agents

Date: Jul 15, 2013

Author: Steve Down

Nerve agents have been detected in urine by a non-targeted high-resolution mass spectrometric method that is comparable to current MS/MS methods and is not limited to a specific panel of compounds.

Journal Highlight: Towards first principles calculation of electron impact mass spectra of molecules

Date: Jul 8, 2013

Author: spectroscopyNOW

The routine calculation of EI mass spectra is based on a combination of fast quantum chemical methods, molecular dynamics, and the stochastic preparation of "hot" primary ions.

New use for old spice: Curcumin as MALDI imaging matrix

Date: Jul 2, 2013

Author: Steve Down

Curcumin, the spice normally used in cooking, has been used successfully as a matrix for MALDI imaging studies of a variety of samples, including fingermarks and tissue, performing at least as well as the classical matrix compound.

Journal Highlight: Comparison of direct mass spectrometry methods for the on-line analysis of volatile compounds in foods

Date: Jun 10, 2013

Author: spectroscopyNOW

This study highlighted the equivalent performances of APCI-MS and PTR-MS for in vitro and in vivo flavour release investigations and provided useful data on the problematic use of sample bags for headspace analyses.

Filter paper prop: Support for biological samples in well plates for forensic drug analysis

Date: Jun 1, 2013

Author: Steve Down

Filter paper has been used as a support in 96-well plates for ten types of biological fluids and tissues in the post-mortem LC/MS analysis of the alkaloid colchicine, in which the calibration curve for dried blood spots can be applied to most of the other sample types.

Cocaine on currency: Higher levels associated with criminality

Date: May 1, 2013

Author: Steve Down

US scientists have analysed 17 years worth of data on the contamination of currency with cocaine to determine the levels which are statistically higher than background, so that banknotes contaminated by drug-related crime rather than general contamination during circulation can be identified.
