Enhanced performance in the determination of ibuprofen 1-β-O-acyl glucuronide in urine by combining high field asymmetric waveform ion mobility spectrometry with liquid chromatography-time-of-flight mass spectrometry.

Abstract

The incorporation of a chip-based high field asymmetric waveform ion mobility spectrometry (FAIMS) separation in the ultra (high)-performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS) determination of the (R/S) ibuprofen 1-β-O-acyl glucuronide metabolite in urine is reported. UHPLC-FAIMS-HRMS reduced matrix chemical noise… (More)
