Burn wounds: Imaging mass spectrometry clues to healing

Date: Aug 17, 2016

Author: Steve Down

The protein changes occurring over time in the skin following serious burn injury have been investigated by imaging mass spectrometry, to try and identify factors which could prevent scar formation.

Beluga whale ages: Aspartic acid isomers by LC/MS

Date: Aug 3, 2016

Author: Steve Down

The age of a beluga whale can be determined from the ratio of its ocular aspartic acid isomers measured by LC/MS in a method that can be extended to other mammals, say researchers in Canada.

Gunshot residue evidence: Secondary transfer from police equipment

Date: Jul 13, 2016

Author: Steve Down

Scientists in the US have used LC/MS and SEM/EDS to measure background levels of gunshot residue in police cars and stations to reduce the risk of false positive tests on criminals by secondary transfer mechanisms.

Marine lipids: Differentiating farmed and wild fish and mussels

Date: Jun 2, 2016

Author: Steve Down

GC-FID and 2D GC/MS methods were used to differentiate wild and farmed fish and molluscs from their lipid contents, a process which should help to identify farmed fish that are being passed off as wild fish.
