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.

Rising Stars of Separation Science: David Steiner
March 29th 2024This month we interview David Steiner, head of product development at LVA GmbH–Lebensmittelversuchsanstalt in Klosterneuburg, Austria about his work developing liquid chromatography–tandem mass spectrometry (LC–MS/MS) multiclass methods for classification of feedstuff, including replication of model complex feedstuffs in the analytical laboratory.
GC–TOF-MS Finds >250 Volatile Compounds in E-Cigarette Liquids
March 29th 2024A study has used gas chromatography coupled to a time-of-flight mass spectrometer to build an electron ionization mass spectra database of more than 250 chemicals classified as either volatile or semi-volatile compounds. An additional, confirmatory layer of liquid chromatography–mass spectrometry analysis was subsequently performed.
