Always I thought that the SS validate the HPLC system before the sample's injections (first 5 or 6) but is true too that we can use the SS for all std injections but, is a risky decision to do that. System suitability testing (SST) is required by USP, FDA and EP to check and ensure on-going performance of an analytical systems and methods. Most SST failures are attributed to poor precision (repeatability) of the autosampler, aging columns, pump problems, or mobile-phase preparation errors. The tests are based on the concept that the equipment, electronics, analytical operations and samples to be analyzed constitute an integral system that can be evaluated as such.
