In this edition of “Inside the Laboratory,” Paola Tiedemann, PhD, an assistant professor of chemistry at Texas Tech University, discusses her laboratory group’s work using headspace sampling techniques like solid phase microextraction coupled to gas chromatography-mass spectrometry (SPME-GC–MS) to chemically characterize odor volatiles from a range of forensic specimens.
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.
