Getting lacquered: Pyrolysis with lithium attachment mass spectrometry for gentle analysis of Japanese lacquers
Date: Mar 15, 2012
Author: Steve Down
Japanese lacquer films have been examined by pyrolysis followed by lithium ion attachment mass spectrometry, which offers a rapid approach to characterisation that gives notably different results from pyrolysis-GC/MS.

Journal Highlight: Towards a universal LC-MS screening procedure - can an LIT LC-MSn screening approach and reference library be used on a quadrupole-LIT hybrid instrument?
Date: Mar 12, 2012
Author:
The aim of the study was to prove whether a recently developed linear ion trap LC-MSn screening approach and reference library can be transferred to an LC-MS/MS system with a quadrupole-LIT hybrid mass analyzer using SmileMS, a sophisticated search algorithm.

Potty about tobacco: Nicotine traces in a Mayan pot confirm its use for storing tobacco
Date: Feb 1, 2012
Author: Steve Down
Nicotine traces have been discovered in a 1300-year-old Mayan flask, providing the first physical evidence of tobacco use by the ancient Mayas and only the second recorded case in which the contents match the hieroglyphics on the outside of the vessel.

Journal Highlight: Applications of mass spectrometry to metabolomics and metabonomics: Detection of biomarkers of aging and of age-related diseases
Date: Jan 16, 2012
Author:
The application of metabolomics to aging research is reviewed for two primary audiences: mass spectrometrists interested in applying their technical knowledge to unanswered questions in the aging field, and gerontologists interested in expanding their knowledge of both mass spectrometry and the most recent advances in aging-related metabolomics.

Expanding doping detection: Screening for carbohydrate-based plasma volume expanders
Date: Jan 15, 2012
Author: Steve Down
The plasma volume expanders mannitol, dextran and hydroxyethyl starch, which are on the WADA prohibited list as masking agents, have been determined in urine by a mass spectrometric method. The procedure has been validated to WADA requirements for accredited laboratories.

Forgeries foiled: EASI mass spectrometry identifies falsified vehicle registration documents
Date: Jan 5, 2012
Author: Steve Down
Forged Brazilian vehicle documents have been detected by ambient mass spectrometry due to the presence of a stabiliser found in printing ink that is absent from genuine documents.

Banged to rights: Firearms distinguished using gunshot residues on fabrics
Date: Dec 15, 2011
Author: Steve Down
Gunshot residues on different types of fabrics have been analysed by high resolution mass spectrometry and the elemental data displayed on ternary graphs to reveal the type of weapon that was fired. The method could provide vital clues in forensic investigations where the firearm has not been recovered.
