SPME all at sea: Extracting methylamines from seawater

Date: Aug 20, 2018

Author: Jon Evans

A novel method for determining the concentration of methylamines in seawater, based on solid-phase microextraction and gas chromatography, is designed to be carried out on board research vessels.

Spotting labels: Determining the efficiency of protein labelling with fluorescent dyes

Date: Aug 20, 2018

Author: Jon Evans

Scientists from Japan and France have developed a method for determining what proportion of proteins in a sample are labelled with fluorescent dyes.

Just like their mother: Analyzing the proteins in snake venom by gel electrophoresis

Date: Aug 20, 2018

Author: Jon Evans

Scientists from Spain and the UK used gel electrophoresis to reveal that venom from a copperhead snake produced asexually, by a process called facultative parthenogenesis, was surprisingly similar to the venom from normal copperheads.

Journal Highlight: Quantification of hydrolyzed peptides and proteins by amino acid fluorescence

Date: Aug 20, 2018

Author: separationsNOW

HPLC using ion‐pairing coupled to fluorescence detection has been used to measure tyrosine, phenylalanine, and tryptophan from hydrolysed peptides without requiring prior derivatization, which will be useful in drug discovery.

More alcohol is seen to make your LC green

Date: Aug 20, 2018

Author: Ryan De Vooght-Johnson

HPLC traditionally uses environmentally harmful solvents, such as acetonitrile, although less harmful alternatives often work just as well. Scientists from the Ahram Canadian University (near Cairo) and Ain Shams University (Cairo) used experimental design to optimise two HPLC systems, both using ethanol and buffer solution, for the analysis of cardiovascular drugs, examining the results using two different green evaluation tools.

New GC investigation of chiral amine separation

Date: Aug 16, 2018

Author: Ryan De Vooght-Johnson

The use of chiral GC to separate pairs of enantiomers is an important technique, but work on the factors that affect separation remains somewhat patchy. Researchers from Chulalongkorn University, Bangkok, investigated the effect of separation conditions and ring substituents on the chiral resolution of a series of 1-phenylalkylamines by GC, using a substituted cyclodextrin as the stationary phase.

Ageing proteins: Plasma biomarkers in healthy people

Date: Aug 15, 2018

Author: Steve Down

Around 220 proteins have been linked to age in a proteomics study of healthy people of all ages, which could be used to predict morbidity and death as well as offer ways to slow the progression of aging.

Chemometrics captures cosmetic contamination compounds

Date: Aug 15, 2018

Author: Ryan De Vooght-Johnson

Glucocorticoid steroids are sometimes illegally added to face masks, but the unambiguous detection and quantification of such compounds can be difficult since they often have similar structures. Researchers from Hunan University, Changsha, China, used LC-MS in combination with an alternating trilinear decomposition (ATLD) algorithm to separate closely related glucocorticoids.

Problem solving: Separating and identifying human serum albumin isoforms

Date: Aug 13, 2018

Author: Jon Evans

As a highly abundant protein in the blood, human serum albumin (HSA) is often a problem, but a new method for separating and identifying different HSA isoforms could also turn it into a solution.

Journal Highlight: Development of a fast gas chromatography tandem mass spectrometry method for volatile aromatic compound analysis in oenological products

Date: Aug 13, 2018

Author: separationsNOW

An innovative GC‐MS/MS method useful for fast analysis of the broad aroma profile of oenological products has been developed, using a set of fifty volatile compounds belonging to the main chemical classes.
