Abstract / Summary

When metabolites are successfully analyzed across different chromatographic methods, it reduces the need to reanalyze samples and allows comparisons to be made across studies using both HPLC and UPLC methods. Ion mobility can play an instrumental role by discriminating isomeric metabolites based on precise measurement of their ion mobility drift times and collisional cross section areas. Covance illustrates how they detected Nefazodone metabolites across two methods. CCS confirmed which isomers were not detected.
