Enhancing the Efficiency of Impurity Analysis
Question:
When impurities are detected by UV under non-volatile mobile phase conditions, does one need to adapt the method to use volatile mobile phase additives for LCMS confirmation?
Answer:
With the use of a Trap-free 2D LCMS system, no additional method development is required because mobile phases can be changed online.
The optimal valve sequence can be constructed by entering the retention times for impurity peaks observed in the first-dimension UV chromatogram, and then a batch schedule can be created to acquire data on multiple impurities and their respective blanks.
