Prep Solution enables a seamless preparative workflow

Prep Solution, ensures that it is simple to scale up from an analytical to a preparative workflow, and makes it easy to
configure parameter settings. It greatly increases the efficiency of preparative workflows.

Easy to understand even for rst-time users Easily isolate the target peaks
The parameter settings in Prep Solution are concise and intuitive, so that all users can operate the system with minimal In case of peak shapes that are different from predictions or other unexpected situations, it is possible to change the

parameters and reanalyzing samples later on, as well as preventing the waste of valuable samples.
