In 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.

I 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 (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.

Beer 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.

The EconoPrep® is designed specifically to automate the difficult, error prone, labor intensive manual processes involved in sample prep for trace analysis. The EconoPrep offers economically priced consumable kits for Environmental and Food Matrices. The system uses reduced solvent making it a green alternative to manual techniques. It automatically performs Extraction, Sample Cleanup and Concentration allowing for same day results. More information Please link to this document and require a form to be filled out.

The 31st Montreux Symposium on LC–MS and MS–MS will be hosted by the International Association of Environmental Analytical Chemistry (IAEAC) at the Aldershof Convention & Exhibition Centre, Berlin?Aldershof, Germany, on 4–6 November 2015.

A highly sensitive and selective mercuric oxide–based reduction gas detector was successfully used for parts-per-billion level gas chromatography (GC) determination of ethylene in various matrices such as in the monitoring of fruit ripening, ambient air, and industrial solvents.

Here we describe a simple and robust high performance liquid chromatography–diode array detection (HPLC–DAD) method for the simultaneous determination of methotrexate (MTX) and sulphasalazine (SSZ) from plasma. MTX and SSZ are used in combination for the treatment of rheumatoid arthritis. Using two detector wavelengths, 304 nm for MTX and 358 nm for SSZ, we were able to selectively quantitate both analytes during the same chromatographic run. The method was validated using quality control samples for critical analytical performance criteria of recovery, reproducibility, selectivity, accuracy, and precision.
