Quick quantification of cactus contamination

Date: Sep 12, 2019

Author: Ryan De Vooght-Johnson

Researchers from Guangxi University (Nanning, China) and the Seed Administration Station of Bijie (China) developed a new method for quantifying Indaziflam residues in pitaya (dragon fruit), a type of cactus, showing its effectiveness with spiked plant samples.

Journal Highlight: Effect of inoculation strategy of non‐Saccharomyces yeasts on fermentation characteristics and volatile higher alcohols and esters in Campbell Early wines

Date: Sep 11, 2019

Author: separationsNOW

The individual fermentation characteristics of several non‐Saccharomyces yeasts for improving the aroma of Campbell Early wine have been studied by GC/MS using PCA to compare the volatile compositions of single and co-fermented wines.

Open database design lists pollutants in the Rhine

Date: Sep 4, 2019

Author: Ryan De Vooght-Johnson

River water can contain a huge number of small molecules, such as pharmaceuticals, industrial chemicals and agrochemicals, making its analysis a challenge. Scientists from the Federal Institute of Hydrology (Koblenz, Germany) devised an LC-MS/MS database method for analysing river water, constructing a new, open database and applying it to samples from the Rhine.

Idiopathic pulmonary fibrosis: New circulatory biomarkers

Date: Sep 4, 2019

Author: Steve Down

Several plasma biomarkers of idiopathic pulmonary fibrosis have been identified and validated by a combination of mass spectrometry methods, which will help to characterise the disease and could lead to better ways of diagnosis.

Journal Highlight: Strong anion exchange‐mediated phosphoproteomics reveals extensive human non‐canonical phosphorylation

Date: Sep 3, 2019

Author: separationsNOW

An unbiased phosphopeptide enrichment strategy based on strong anion exchange chromatography (UPAX) has been devised for identification of His, Arg, Lys, Asp, Glu and Cys phosphorylation sites on human proteins by mass spectrometry‐based phosphoproteomics.

Catching cucumber crop contamination with ECD determination

Date: Sep 2, 2019

Author: Ryan De Vooght-Johnson

The organophosphate insecticide ethion can be harmful to human health so residue levels on food crops need to be monitored. Researchers from the Sher-e-Kashmir University of Agricultural Sciences (Srinagar, India) used GC with an electron capture detector (ECD) to investigate ethion residue levels on cucumbers.
