Staying one jump ahead: Screening antibiotics in frog legs by accurate mass spectrometry

Date: Jun 1, 2012

Author: Steve Down

Veterinary antibiotics have been detected in frog legs and other aquacultured fish by an LC/MS method using high resolution mass spectrometry, confirming that most frog legs imported into the US have residues above regulatory action levels.

Pyrethrins exposed: Flower extracts tested by LC/MS with direct electron ionisation

Date: May 15, 2012

Author: Steve Down

The six pyrethrins in chrysanthemum flower heads and a pyrethrum extract have been measured by an LC/MS method with electron ionisation, sidestepping problems with thermal stability in the first study of its type.

Journal Highlight: MALDI-MS investigation of pollen and their classification by multivariate statistics

Date: May 14, 2012

Author: spectroscopyNOW

Matrix-assisted laser desorption/ionization mass spectrometry was applied to the analysis of pollen extracts and milled pollen samples and the data were explored for characteristic peak patterns which could be subjected to a multivariate statistical analysis.

Journal Highlight: Expanding the data depth for the analysis of complex crude oil samples by FTICR MS using the spectral stitching method

Date: May 10, 2012

Author: spectroscopyNOW

Spectral stitching using small SIM windows was used to overcome the suppression effects observed with crude oil samples in FTICR MS caused by the sheer number of individual compounds present.

Mobility differences: Cocaine cutting agents identified

Date: May 1, 2012

Author: Steve Down

Cocaine has been differentiated from the common cutting agents used in illicit samples by differential mobility spectrometry-mass spectrometry, providing a rapid alternative to chromatographic methods to assist hard-pressed lab analysts.

It takes an age: Art pigments influence degradation of protein-based binders under UV light

Date: Apr 15, 2012

Author: Steve Down

The ageing of protein-based binders in works of art by UV light is affected by the presence of pigments, say European scientists, who followed the changes in rabbit glue. The findings should be useful in the fields of restoration and conservation.

Journal Highlight: Finding the right balance - a personal journey from individual proteins to membrane-embedded motors

Date: Apr 9, 2012

Author:

The present review, based on the FEBS/EMBO Women in Science Lecture, offers a personal view of the transition from determining the mass of an individual protein to elucidating the structure and dynamics of heterogeneous assemblies in the megadalton mass range.

Cyclic exposure of poultry to drugs: Antimicrobial drugs discovered in feather meal used as food supplement

Date: Apr 1, 2012

Author: Steve Down

Animal feed supplements made from poultry feathers contain antimicrobial drugs which will re-enter the food chain when fed to farm animals, say US researchers, in the first study of its kind.

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.
