A chromatography system that drifts out of spec — noisy baselines, poor resolution, tailing peaks — doesn’t just slow down a lab, it puts the reliability of every result that follows into question. Knowing the theory behind Gas Chromatography (GC) and Liquid Chromatography (LC) is only half the job; the professionals who keep laboratories running are the ones who can diagnose what is actually going wrong and fix it.

This training course builds that diagnostic skill set from the ground up, covering how GC and LC systems are built and operated, then moving into hands-on troubleshooting for injectors, columns, detectors, and contamination issues, so participants leave able to keep chromatographic systems accurate, compliant, and reliable.

Course Objectives

By the end of this training course, participants will be able to:
