LCGC North America Application Note Alert Having trouble viewing this email? Click here Sample Prep Extraction of Benzodiazepines Using QuEChERS This application describes an easy, fast, and effective method using QuEChERS for the quantitative analysis of benzodiazepines in whole blood. Extraction of Phthalates from Polyvinyl Chloride A simple 15-min extraction method is all that is needed to quickly prep plastics for phthalate analysis. Identifying Low-Level Odorants in Wine Automated immersive sorptive extraction using high-capacity HiSorb probes, with GC–MS can be used to screen wine for ppb levels of two yeast-derived spoilage compounds.   LC-MS Simultaneous Analysis of Catecholamines and Metanephrines in Urine by LC-MS/MS Analysis of these polar compounds using reversed-phase LC can be difficult due to limited chromatographic retention, which results in poor separation of the analytes from closely eluting matrix interferences. Novel Stationary Phase Fights Cardiovascular Disease LC–MS methods are challenging because they are isomers with the same m/z. We show successful separation on a novel stationary phase without derivatization. Cannabis Potency Using Low-Cost HPLC A simple isocratic HPLC method for the testing of Cannabis. The DLC-10 is a small footprint, easy to use and low-cost HPLC system. The included fixed wavelength detector has good signal response when using the 214 nm Zinc lamp.   GC How Much Lightning in in Your Morning Jolt A study of the concentration of caffeine and other organic coffee marker molecules in fast food and home brewed coffee.   HPLC Rapid Separation of Basic Drug Compounds Under Alkaline pH Conditions on pH-Stable, Hamilton PRP™-C18 In this study a generic, 5-min linear gradient was used to separate six basic drug compounds on a short (50 mm) PRP-C18 column.
