GC TROUBLESHOOTING AND MAINTENANCE
TRAINING COURSE
A logical approach to GC Troubleshooting and Maintenance is explored in this one-day 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.
We limit numbers to 12 per course so that each delegate gets the opportunity to ask questions and fully participate in tutorial exercises.
When delivered on-site we can design the course material to suit your specific training needs.
This course is designed for those relatively new to GC and ideally will follow-on from attendance to the Fundamental GC training course.
