Описание: QC test mixes (probes) serve a dynamic purpose in ensuring the inertness, reproducibility, and functionality of a specific GC or GCMS method. The test mix chemistry of individual compounds to make up such a probe can vary widely depending on the column chemistry, detector selectivity, and method acquisition parameters. The presentation focuses on what constitutes a good QC test mix, what data (test mix) features to review, the steps to maintain data quality, and what to do when data quality decreases or fails the customer’s QC guidelines. Issues such as, when to change your liner, gold seal, guard chip, and column maintenance will be discussed. The test probe mix utilized in the presentation will be the DB-5MS column test mix as an example of analytes with active functional groups to adequately exercise the flow path and the DB-5MS column’s analytical state. This webinar will be presented from a forensic drug chemistry point of view but will be applicable to most GC or GCMS applications and sample matrices.
