LCGC North America Application Note Alert Having trouble viewing this email? Click here GC–MS Phthalate Analysis Using a Standardized Method This application note presents thermal extraction of phthalates in accordance with IEC Method 62321-8 using a 6150 Pyroprobe. GC–MS Analyses of PFOS and PFOA Precursors in Textile Products This report examines the use of two optimized GC–MS methods to detect trace amounts of PFOA and PFOS precursors, and to quickly screen for them in textile articles.   LC–MS 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.   LC Novel HPLC Materials for Biopharmaceutical Separations Characterization of biologicals presents challenges compared to small molecules. Advanced wide pore particles have been introduced to better understand these proteins. UHPLC Columns for Oligonucleotide Analysis Oligonucleotide analysis with our new Develosil UHPLC C18 and C30 columns demonstrates well resolved peaks for single nucleotide changes in length up to 40-mer.   General Hydrogen Faster Safer Note discusses the benefits of switching from Helium to Hydrogen for carrier gas in gas chromatography.
