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.

Journal Highlight: Fast detection of leaf pigments and isoprenoids for ecophysiological studies, plant phenotyping and validating remote-sensing of vegetation

Date: Jan 23, 2017

Author: separationsNOW

A simple, rapid and cost-effective HPLC protocol is described for the rapid analysis of a wide range of chlorophylls, carotenoids and tocopherols in leaves that contribute to changes in leaf optical properties.

Chemical profiling of cocaine: a powerful tool for drug enforcement

Date: Jan 12, 2017

Author: Ryan De Vooght-Johnson

Chemical profiling of cocaine has been performed for the first time in China, successfully separating over 180 different samples into seven main groups of possible similar origin. The study, which used a form of ultra-high performance liquid chromatography suitable for routine analysis, provides intelligence for cracking down on drug trade in the country.

Controversial caffeine caught by clever LC-MS/MS method

Date: Jan 1, 2017

Author: Ryan De Vooght-Johnson

Most of us like the odd cup of tea or coffee, but a very high caffeine intake from oral sprays, e-cigarettes or powdered caffeine can have serious health consequences, particularly when combined with high alcohol consumption. Researchers at the University of Tennessee have developed a novel method of simultaneously determining the concentrations of caffeine and its metabolites in plasma by LC-MS/MS with ESI-MS/MS.

Journal Highlight: Determination of urine albumin by new simple high-performance liquid chromatography method

Date: Dec 19, 2016

Author: separationsNOW

A simple HPLC method has been developed for the determination of albumin in patients' urine samples without coeluting proteins, proving to be more sensitive than immunoturbidimetry.

Salmonella: catch me if you Cayenne!

Date: Dec 13, 2016

Author: Ryan De Vooght-Johnson

Microbial beasts use evil trickery to establish themselves on supermarket shelves. However, they have been met by the wrath of American scientists, who have crafted a speedy, selective method of HILIC-HPLC-MS for antimicrobial acid identification in foodstuffs.

Analysing aldehydes: UHPLC reveals the chemical weapons that crush crustacean reproduction

Date: Dec 1, 2016

Author: Ryan De Vooght-Johnson

Microscopic diatoms may be small, but these silica-clad plankton have their own chemical weapons, producing compounds, such as polyunsaturated aldehydes, that inhibit some of their predators. Scientists from Jena University in Germany have produced an improved method for detecting such compounds, using modern ultra-high performance liquid chromatography.
