Click here Featured Application Note Practical Ultrahigh-Performance Liquid Chromatography (UHPLC) Increasing efficiency and resolution whilst reducing costs have driven the uptake of UHPLC. We outline how technologies evolve to give new options to chromatographers.   LC-MS Analysis of Phospholipid Classes by iHILIC®-Fusion Ten classes of phospholipids were analyzed by HILIC–MS/MS using an iHILIC®-Fusion column. The applicability of the method for potential clinical application is shown.   GC Analysis of Oxygenates and Aromatics Using ASTM Methods This study shows how PerkinElmer’s Arnel Model 4004 GC Analyzer provides greater flexibility and productivity for ASTM testing methods D4815 and D5580.   LC Coupling Direct Injection and Online SPE This application note shows the development of a multiresidue online SPE LC–MS/MS method coupled to direct injection for the analysis of 26 pesticide metabolites. 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. Guide for Successful (U)HPLC Method Transfer Method transfer is a common practice in HPLC. Read about instrumental parameters, challenges, and solutions to consider during transfer of an analytical HPLC method.   SEC Identifying Short-Chain Branched Polymers Short- and long-chain branching in polymers are distinguished and quantified by SEC coupled to multi-angle light scattering and differential viscometry detectors.   Sample Prep SPE Analysis of Delta9-tetrahydrocannabinol in Plasma Selectivity and sensitivity of the LC–MS/MS method for the determination of Δ9-tetrahydrocannabinol and its metabolites in plasma, usually measured by GC–MS. Automation for Every Laboratory Accurate and precise preparation of calibration standards is vital for quantitative environmental analysis. ePrep’s Sample Prep Workstation offers improved efficiency. LipiFiltr® Clean-Up of Oil-Based Cannabis Products This application note outlines the performance benefits of using the LipiFiltr® cartridge in applications involving pesticide analysis of oil-based cannabis products.
