Customizing Problem II

Hello,how can I calculate the relative retention time (RRT) of an impurity peak related to the main peak (= peak with the highest peak area) using custom fields and other functionalities of Empower 2?Thank you very much for every hintRegardsFlorian


  • You don't need to use customfields, its already in!

    In your processing method, flag your main peak as default peak.

    Now take a look at the RT Ratio in your peak table.


  • BJ,
