Journal Highlight: Molecularly imprinted core-shell magnetic nanoparticles for selective extraction of triazines in soils

Date: Apr 24, 2017

Author: separationsNOW

Spanish scientists have synthesized a propazine-imprinted polymer on the surface of modified magnetic nanoparticles for use in the solid-phase extraction of triazine pesticides from soil samples prior to analysis by HPLC.

Hot Pepper Compounds Caught by Cool Coulometric Detection

Date: Apr 17, 2017

Author: Ryan De Vooght-Johnson

Whether you love it or loathe it, you may well want to know how much of that hot pepper taste is in the food you buy. Scientists from Brussels, Tokyo and Osaka have developed a novel HPLC method using coulometric detection to quantify capsaicinoids, the compounds that give the hot sensation.

Chemists carefully compare chromatography with immunoassay for VPA

Date: Apr 2, 2017

Author: Ryan De Vooght-Johnson

Valproic acid is an anti-convulsant medication taken by epileptic patients; its plasma concentrations have to be monitored in order to minimise side effects. Researchers from the Second Military Medical University in Shanghai compared the effectiveness of using either LC-MS/MS or an immunoassay technique for these measurements.

Journal Highlight: Caviar versus brill eggs: A novel high performance liquid chromatography-mass spectrometry application for evaluating cosmetic ingredients composition

Date: Mar 27, 2017

Author: separationsNOW

The lipids in sturgeon and brill roe, which are used as lipid sources in beauty creams, have been analyzed and compared using GC/MS for fatty acids and HPLC coupled with high resolution MS for triacylglycerols.

Brain painkiller reaction rates revealed in real-time

Date: Mar 15, 2017

Author: Ryan De Vooght-Johnson

The pharmacokinetics of the commonly-used synthetic opioid painkiller tramadol are of great interest, but most work to date has focused on the levels in plasma, rather than in the brain. In order to obtain information on the kinetics of tramadol and its main metabolite, O-desmethyltramadol, in rat brains, researchers from Wuhan University used a procedure involving microdialysis of cerebral fluid, followed by LC-MS/MS.

LC-MS/MS shines light on sunscreen UV filters

Date: Mar 1, 2017

Author: Ryan De Vooght-Johnson

The detection of UV filters, used in sunscreens and other cosmetics, is a topic of interest for analysts working on their possible health effects, for those concerned with consumer protection and also for environmental scientists, since these products can have adverse environmental consequences, such as damaging coral. Scientists in Beijing have developed an improved method for detecting a range of different UV filters using LC-MS/MS.

Journal Highlight: An HPLC method for the determination of selected amino acids in human embryo culture medium

Date: Feb 20, 2017

Author: separationsNOW

A novel HPLC method with fluorescence detection has revealed changes in the levels of selected amino acids in the culture medium before and after human embryo cultivation.

Gender Bender Steroids in the Alabama Mud Detected by UHPLC

Date: Feb 15, 2017

Author: Ryan De Vooght-Johnson

Steroid pollutants tend to pass through sewage works and accumulate in estuaries, where they act as endocrine disruptors and may harm wildlife. Scientists from Auburn University, Alabama have developed a new UHPLC-MS/MS method for the detection of these steroids from estuarine sediments.

LC-MS shows e-cigarette packs lack accuracy

Date: Feb 1, 2017

Author: Ryan De Vooght-Johnson

E-cigarettes are increasing in popularity, but there is a lack of good research into their content and effects. Italian researchers examined the liquid and vapour from a variety of e-cigarettes by LC-MS/MS, finding that many gave inaccurate nicotine contents on their labels, and that they often contained significant amounts of various nicotine analogues, possibly exposing users to unknown risks.
