GC Troubleshooting and Maintenance

Live Online

Instructor-led Training

A logical approach to GC Troubleshooting and Maintenance is explored in this course. Commonly encountered problems and best practices are examined for all major system components including gas handling, inlet system, oven, column and detector.

Examination of separation chemistry, interrogation of poor peak shape and retention problems are a fundamentally important part of the course, leading to increased awareness of troubleshooting principles.
