Chemical Purification Analysis and Screening core facility (CPAS)

OVERVIEW

CPAS offers its expertise in chromatographic separation and purification (MPLC, HPLC, UHPLC), mass spectrometry detection, identification and quantification (LC-MS SQ, LC-MS QqQ, LC-MS ToF, LC-MS QToF, GC-MSD and GC-MS QToF and MALDI TOF). The services also include Circular Dichroism, general spectroscopic characterization (UV, FTIR), lyophilization (benchtop and general purpose freeze-dryer), synthesis (microwave reactor), ADME screening (Parallel Artificial Membrane Permeability [PAMPA] and drug solubility evaluation), and high-throughput screening development capability (liquid handling robot and multimode plate reader). Instruments at CPAS are available 24/7 upon reservation in self-service for users who completed the training.
