Autosampler Carryover
LCGC North America
This month's column discusses the presence of sample peaks in chromatograms when only blanks are injected -- commonly called carryover. Most carryover problems can be eliminated by performing one or more of the approaches discussed in this column.
TD-GC–MS and IDMS Sample Prep for CRM to Quantify Decabromodiphenyl Ether in Polystyrene Matrix
April 26th 2024At issue in this study was the certified value of decabromodiphenyl ether (BDE 209) in a polystyrene matrix CRM relative to its regulated value in the EU Restriction of Hazardous Substances Directive.
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.
Inside the Laboratory –– Women in Separation Science Edition
April 25th 2024Inside the Laboratory is a joint series with LCGC and Spectroscopy, profiling analytical scientists and their research groups at universities all over the world. This series spotlights the current chromatographic and spectroscopic research their groups are conducting, and the importance of their research in analytical chemistry and specific industries. In this “Inside the Laboratory –– Women in Separation Science” special edition PDF, we profile four industry leaders and the impact that their research is having in specific fields such as environmental analysis, forensics, national security, and drug development.
