During repeated routine PQA monitoring of your peptide, it is essential to provide solid evidence that the results are reliable, and to maintain the performance of the system. For this purpose, bracket your sample injections between injections of known standards that can demonstrate the ability of the system to reproduce expected results immediately before and after the product injections.

Chromeleon CDS software lets you evaluate your system by running injections of the Check Standard type and processing them with a processing method that includes a system suitability test (SST). Optionally, you can use Intelligent Run Control (IRC) to stop your system from running any further injections if the SST has failed.
