Adrian Tordiffe from the Veterinary Faculty of the University of Pretoria in South Africa, is working to establish baseline metabolic profiles for captive and free-ranging cheetahs to investigate the unusual medical conditions that the animals develop in captivity. He spoke to The Column about his work and about the role that chromatography plays.
Researchers from Zhejiang University, China, have created a graphene-coated polymeric stationary phase and demonstrated its performance separating inorganic anions, organic acids, carbohydrates, and amino acids using anion exchange chromatography.
3M, the science-based technology company, has commissioned the National Institute for Bioprocessing Research and Training (NIBRT) to conduct in-depth research into their Emphaze AEX Hybrid Purifier, a single use plug and play filter matrix.
An autosampler for a standard gas chromatography (GC) or GC–mass spectrometry (MS) system was adapted to perform simple static headspace sampling, instead of using a separate, and potentially more complicated, headspace sampling unit.
Novel psychoactive substances pose a major challenge for forensic toxicology and drug-seizure laboratories because of the scale and speed at which these new “designer drugs” are entering the market. To keep pace with the threat, laboratories require robust full-scan detection techniques capable of both targeted drug screening and the identification of unexpected compounds too. Here, a full-scan gas chromatography (GC) coupled to high-resolution accurate mass (HRAM) approach for the profiling of known and unknown drugs of abuse is presented.
