Practical HPLC Troubleshooting and Maintenance
2 Day Course
A logical approach to HPLC Troubleshooting and Maintenance is fully explored within this two day course. Commonly encountered problems and best practice are reviewed for all major system components including mobile phase, pump, injection system, 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.
Practical exercises are fundamental to this course and familiar 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 HPLC 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 two day course.
Who is this course for
This course is designed for those relatively new to HPLC, or for those users of HPLC systems who want to gain a deeper insight of their instruments. Ideally will follow-on from attendance to the fundamental HPLC training course.
Some previous knowledge of chromatography and basic experience are recommended. A good grounding in Chemistry is also beneficial.
