Access to a comprehensive source of certified reference materials in various forms - powders and solutions - is vital for clinical and forensic laboratories, to ensure the correct identification of substances and the accuracy of results, and there is an increasing customer demand for ISO Guide 34:2009 certification. Jenny Button, Product Specialist, LGC Standards, UK, discusses certified reference materials and the importance of ISO Guide 34 to both manufacturers and end-users.

Human beings have long consumed mind altering drugs to attain a euphoric high. These illegal drugs are obtained directly from natural substances including plants or they are chemically synthesized. Monitoring consumption of abused drugs is important in workplace settings, crime scene investigations, forensic toxicology and other related areas.

CE–MS using noncovalent coated capillaries provides advantages for purity and stability analysis of biopharmaceuticals.

LC–MS and CE–MS are the go-to techniques for characterizing biologics, but often help is needed from a range of other methods.

Automated column and mobile phase screening is the current trend in the pharmaceutical industry to develop chiral methods. This study presents comprehensive strategies for automated rapid chiral HPLC method development including normal-phase, reversed-phase and polar organic phase separation modes.
