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.
GC–MS Analysis of PFAS Expands Knowledge of Toxicokinetic Data
