India is an increasingly influential player in the global pharmaceutical market. A pilot study, conducted in two major cities in India, Delhi and Chennai, explored the proliferation of substandard and counterfeit drugs in the market and discussed how the Indian state and federal governments could improve drug regulation and regulatory enforcement to combat this.

A provider of contract laboratory services and manufacturer of scientific instruments in the US, has opened a new European laboratory and office in Warwickshire, UK.
In this application note GPC is used to easily and reliably analyze the molecular mass distribution of industrially produced polyacrylnitrile (PAN). Since this GPC application uses DMF and a small amount of lithium bromide as mobile phase, it will work on a standard HPLC system without any modifications.

Faculty of Health Sciences at the University of Copenhagen will open the doors of its new research centre, The Novo Nordisk Foundation Centre for Protein Research. The centre is the result of an historic donation from the Novo Nordisk Foundation, which in 2007 gave the university €80 million for its establishment.

The purity of the solvent used for the mobile phase is one of many factors affecting the quality of chromatographic data obtained from high-performance liquid chromatography (HPLC). A typical reversed-phase HPLC gradient elution requires equilibration of the column to the initial conditions with several column volumes of the weak (aqueous) solvent.
