Practical GC Troubleshooting and Maintenance
1 Day Course
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.
Practical exercises are fundamental to this course and industry standard equipment will be used to carry out a wide range of laboratory-based tasks.
- We limit numbers to 6 per course so that each delegate gets the opportunity to ask questions and fully participate in practical exercises
- When delivered on-site we can design the course material to suit your specific training needs
- Customisable written assessments are available if required
Course Overview | Download course details »
All components of the GC system and associated problems are systematically studied. The use of chromatograms as diagnostic tools is explored in depth, including baselines, peak shape and retention time inconsistencies, spurious peaks, etc.
Laboratory based sessions are included to make an all-encompassing and thorough one day course
Who is this course for
This course is designed for those relatively new to GC, or for those users of GC systems who want to gain a deeper insight of their instruments. Ideally will follow-on from attendance to the Fundamental GC training course.
Some previous knowledge of gas chromatography and basic experience are recommended but not essential.
