This article describes a sample extraction and cleanup procedure for removing toxic PCB congeners from other congeners in polluted marine and estuarine sediment and fish. The resulting extracts are analyzed by GC–ECD.
High-Throughput 4D TIMS Method Accelerates Lipidomics Analysis
April 25th 2024Ultrahigh-pressure liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) had been previously proposed for untargeted lipidomics analysis, but this updated approach was reported by the authors to reduce run time to 4 min.
