LCGC North America Application Note Alert Having trouble viewing this email? Click here HPLC Monitoring of Mammalian Cell Culture Media This application note describes the monitoring of nutrient uptake and excreted waste products in mammalian cell culture media with HILIC 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. 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.   Sample Preparation LipiFiltr® Cleanup for High-Lipid Food Samples The application shows the benefits of using the LipiFiltr® cartridge in multi-class, multi-residue analysis for a wide range of pesticides in complex, high fat samples.   General Characterization of Protein-DNA Complexes Quantifies affinity, stoichiometry of biomolecular assemblies, helping understand the mechanism of interaction and develop therapeutics that target and modulate them.   LC/HPLC Simultaneous Analysis of Monoclonal Antibodies The Thermo Scientific Vanquish Duo system for Dual LC can run two methods simultaneously on one instrument, regardless if identical chromatographic conditions are used.
