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). 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). The facility provides research lab training and assistance so users can operate any instruments necessary to successfully accomplish their research projects.
