Neue AppNote: Nachweis von Dopingmitteln in Pferdeurin mit DPX-GC/QQQ

Die vollständig automatisierte DPX-LVI-GC/QqQ-Methode ermöglicht schnelle und zuverlässige Ergebnisse bei gleichzeitig niedrigen Bestimmungsgrenzen


This application note describes a fully automated analysis method for selected equine doping compounds in equine urine.
A GERSTEL MultiPurpose Sampler (MPS) with Disposable Pipette Extraction (DPX) option is employed for extraction and cleanup. After gas chromatographic separation the analytes are detected by a triple-quadrupole mass spectrometer (QqQ-MS).
The method is rugged, provides an adequate cleanup of the complex sample matrix and shows good limits of detection, from below 0.1 to just under 10 ng/mL for the various analytes that are determined.
