Miniaturized High-Performance Chiral Liquid Chromatography
May 22nd 2015Stereoisomers of chiral compounds - two different forms (isomers) that are identical in composition but are non‑superimposable mirror images of one another - can have dramatically different effects in the human body making it important to ensure the purity of enantiomeric mixtures produced in drug development.
Gyula Vigh Receives Arnold O. Beckman for Separation Techniques

Beckman Award for Outstanding Scientific Achievements in the field of electrodriven separation techniques sponsored by Sciex Separations, a division of AB Sciex (Massachusetts, USA).
Digital Microfluidics Enables Analysis of Multiple Steroid Hormones in Core-Needle Biopsy Samples
May 22nd 2015Researchers from the University of Toronto in Canada have developed a novel approach using digital microfluidics to analyze multiple steroid hormones in small tissue samples (1–10 mg) collected using core-needle biopsy (CNB) sampling.
Detecting Substandard Drugs in Africa
May 19th 2015In developing countries, access to medicine is often limited. To make matters worse, widespread counterfeiting often means that even when patients get access to drugs, the drugs are of poor quality. Dr. Mélisande Bernard, of the Agence Générale des Equipements et Produits de Santé, the technical and pharmaceutical service of the public hospital system of Paris, France (Assistance Publique–Hôpitaux de Paris), is helping to address this problem by developing chromatographic methods to detect substandard cardiovascular drugs in Africa.
Event Preview: Virtual Symposium on Applied Separation Science (VSASS 2015)
May 13th 2015The first Virtual Symposium on Applied Separation Science (VSASS) will be held on 25–29 May 2015 on-line. Accessible via a web link (www.vsass.org), the entire symposium will be held on-line including posters, workshops, and sessions.
The LCGC Blog: A Disconnect Between Science Research and Science Education Research
May 12th 2015Now that I have been at UT Arlington for 10 years, I have had many opportunities to refine my own approaches to teaching, in hopes that the learning curve to achieve meaningful learning for students is not as steep as the one I had to manage.
The LCGC Blog: Troubleshooting Retention Time Issues in Reversed Phase HPLC
May 12th 2015I got into a discussion with a learned colleague recently regarding the relationship between peak height and flow rate in gradient HPLC. We haven't really resolved the discussion, there are suggestions regarding "peak focussing," the number of column volumes in relation to the gradient volume (number of column volumes per minute), increases in efficiency etc.
Markes International Wins Queen’s Award for Enterprise
May 6th 2015Markes International (Llantrisant, UK) has been awarded a 2015 Queen’s Award for Enterprise in International Trade decreed by Her Majesty The Queen of Great Britain, on the recommendation of the Prime Minister, David Cameron. The awards are announced each year on the Queen’s birthday, 21 April.
Analyzing Shipwrecked Beer from 1840s Using GC–MS
May 6th 2015Beer from a 1840s shipwreck in the Baltic Sea has been analyzed by a team of scientists at the VTT Technical Research Centre in Finland. Using a variety of chromatography techniques - including gas chromatography coupled to mass spectrometry (GC–MS) and high-performance anion-exchange chromatography (HPAEC) coupled to MS - the team compared the beer with modern-day varieties and found they were not too dissimilar.
Agilent Technologies and Scion Announce GC Instrument Control Agreement
May 6th 2015Agilent Technologies (California, USA) and Scion Instruments (California, USA) have announced a gas chromatography instrument agreement, which will allow users to operate instruments from both manufacturers in each company’s chromatography data systems.
Investigating the Link Between PBDE Exposure and Feline Hyperthyroidism
May 6th 2015Exposure to flame retardant additives could be a contributing factor to the occurrence of feline hyperthyroidism (FH) in Swedish cats, according to a new study. The authors also suggest that pet cats can be studied as markers of environmental contamination in the home.
