Erasable inks: Ambient mass spectrometry spots forgeries

Date: Jun 15, 2014

Author: Steve Down

The ink from erasable pens can be detected after it has been rubbed off the paper by an ambient mass spectrometry technique that will be able to check the security of suspected forgeries.

Indoor air quality: The value of proton transfer reaction mass spectrometry

Date: May 17, 2014

Author: Steve Down

The versatility of the oft-forgotten technique proton transfer reaction mass spectrometry for indoor air applications has been demonstrated by European scientists who carried out five contrasting experiments, including the emission of volatiles from a laser printer and building board.

Journal Highlight: On-chip spyhole mass spectrometry for droplet-based microfluidics

Date: May 12, 2014

Author: spectroscopyNOW

For efficient coupling of droplet-based microfluidics with mass spectrometry, a spyhole drilled on the top of a microchip is used to sample the passing droplets by electrostatic spray ionization.

Plastic e-waste management: Rapid, robotic flame retardant detection

Date: May 2, 2014

Author: Steve Down

A simple mass spectrometry method has been applied to the detection of brominated flame retardants in plastic e-waste, allowing it to be screened and categorised before recycling or dumping in landfills.

Serum or plasma? Mass spec metabolomics decides

Date: Apr 15, 2014

Author: Steve Down

The ability of the complementary techniques of GC/MS and LC/MS to compare the metabolomes of rat plasma and serum has been investigated by Chinese scientists, who found that GC/MS has better reproducibility.

Journal Highlight: A quantitative analysis of the polyamine in lung cancer patient fingernails by LC-ESI-MS/MS

Date: Apr 7, 2014

Author: spectroscopyNOW

A quantitative analysis of eight polyamines in lung cancer patient fingernails for diagnosis and to assess the depth of the disease was conducted by LC/MS/MS following reaction with 4-(N,N-dimethylaminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole.

The lowdown on cancer: Metabolite mass spectrometry for cancer screening

Date: Apr 2, 2014

Author: Steve Down

A new way to identify cancers from the low-molecular-mass metabolites that show up in the mass spectra of serum has been devised by Korean scientists, who used it to distinguish colorectal cancer from gastric and breast cancer.
