Going wild: Pesticide screening method for poisoned wildlife and pets

Date: Dec 16, 2012

Author: Steve Down

Suspected poisoning of wildlife, pets and livestock can be rapidly assessed by a new multi-residue LC/MS/MS method for pesticides developed by Scottish government chemists.

Journal Highlight: Implementation of proton transfer reaction-mass spectrometry (PTR-MS) for advanced bioprocess monitoring

Date: Dec 10, 2012

Author: spectroscopyNOW

The implementation of PTR-MS technology for on-line monitoring of volatile organic compounds in the off-gas of bioreactors is described, including the development of an interface between the bioreactor and an analyzer for continuous sampling.

Single cell spectrometry: Inkjet printing and ambient mass spectrometry for lipid profiling

Date: Dec 2, 2012

Author: Steve Down

The phospholipids in single cells that have been printed using a custom inkjet printer were analysed by liquid extraction surface analysis coupled to nanospray mass spectrometry, allowing cell types to be differentiated.

Bacterial identity parade: Volatile profiles classify Gram-negative species within minutes

Date: Nov 15, 2012

Author: Steve Down

Gram-negative bacteria can be identified and distinguished after just 24 hours of growth via their volatile compound profiles using ion/molecule reaction mass spectrometry in a test that takes just 3 minutes and is suitable for clinical testing.

Journal Highlight: Fragmentation of toxicologically relevant drugs in negative-ion liquid chromatography-tandem mass spectrometry

Date: Nov 12, 2012

Author: spectroscopyNOW

The class-specific fragmentations of toxicologically relevant compounds in negative-ion MS–MS have been reviewed by collating more than 500 spectra from three libraries.

Tea protection racket: Protectants compensate for matrix effects in pesticides analysis of tea

Date: Nov 1, 2012

Author: Steve Down

A set of protectants has been evaluated for the GC/MS analysis of pesticides in three different types of tea to compensate for the matrix effects that complicate the gas chromatographic behaviour.

Conserving plastic objects in museums: Emitted volatiles act as exhibit degradation markers

Date: Oct 15, 2012

Author: Steve Down

Specific volatiles emitted from plastic objects in museums have been identified by SPME-GC/MS, giving a series of degradation markers and that will help with the preservation of valuable exhibits.

Journal Highlight: Ultrahigh resolution mass spectrometry and accurate mass measurements for high-throughput food lipids profiling

Date: Oct 8, 2012

Author: spectroscopyNOW

Accurate mass measurements by ultrahigh resolution mass spectrometry at R = 100,000 were used to show a detailed molecular composition of diverse edible oils and fats.

Putting pen to paper: Nib-assisted paper spray mass spectrometry for drug screening

Date: Oct 5, 2012

Author: Steve Down

A suite of amphetamines has been detected by paper spray mass spectrometry using a novel nib device as a sprayer that allows continuous elution for several minutes and provides high sensitivity.
