Abstract / Summary
This data demonstrates the advantage of ion mobility separation combined with DIA for DMPK studies. Use of this orthogonal separation technique is capable of significantly improving the confidence and speed with which drug metabolism and degradation products can be identified. The dextromethorphan metabolite 2x + O product ion signals are relatively minor when compared to interfering matrix ions, these are not separated using traditional LC-MS analysis and therefore can complicate assignment. When this same data is analyzed incorporating the ion mobility dimension, matrix product ions are removed, and therefore, metabolite product ions are easily identified and confidently assigned.
