Technical Note – Ultra-High Performance Liquid Chromatography Photo Diode Array Ultraviolet Single Quadrupole Mass Spectrometry (UHPLC-PDA UV-MS)

This technical note outlines the utility of ultra-high performance liquid chromatography (UHPLC) coupled with photo diode array ultraviolet spectroscopy (PDA UV) detection and single quadrupole mass spectrometry (MS) detection in a series as a complementary technique to gas chromatography-election ionization-mass spectrometry (GC-EI-MS) in seized drug analysis.
