June 19th 2014A simple, rapid, and robust UHPLC method for the simultaneous determination of polyphenols, methylxanthines, sweeteners, and flavouring substances as well as some common preservatives has been developed using an automated method scouting and method optimization workflow.
Profiling MDMA Impurities Using HS–SPME
June 19th 2014Profiling impurities in MDMA (also known as ecstasy) is essential to forensic science as different profiles can provide clues about the source. Two researchers from Michigan State University (Michigan, USA) investigated the effect of liquid–liquid extraction (LLE), headspace solid-phase microextraction (HS–SPME), and different gas chromatography temperature programmes highlighting the need for standardized procedures.
New LC–MS–MS Method to Detect Counterfeit Drugs
June 19th 2014Researchers at the Universite de Montreal in Canada have developed and validated a new liquid chromatography tandem mass spectrometry (LC–MS–MS) method to identify compounds present in suspected counterfeit or even adulterated erectile dysfunction drugs. According to the study published in the Journal of Chromatography A, the method has now been introduced to the Inspectorate Laboratory Programme at Health Canada (Canada).
