HPLC Troubleshooting and Maintenance
Classroom Based 1 Day Course: Level 2

Course Description:
A logical approach to HPLC Troubleshooting and Maintenance is fully explored within this one-day course. Commonly encountered problems and best practice are explored for all major system components including Eluent, Pump, Injection system, Column and Detector. Troubleshooting separation chemistry, interrogation of poor peak shape and retention problems are a fundamentally important part of the course, leading to increased awareness of separation chemistry. Practical exercises are fundamental to this course and familiar equipment can be used to carry out a wide range of laboratory-based tasks.

Fast & Ultra Fast HPLC
Classroom and Laboratory Based 1 Day Course: Level 4

Course Description:
This course is designed as a comprehensive introduction to the principles and practice of Fast and Ultra-Fast HPLC.
The course is a mix of theory, computer simulation and lab sessions that allow the student to quickly gain knowledge on the theory, practice and limitations of the common approaches to speeding up HPLC analysis. The main factors in speeding up analysis – reduced column dimension, sub 2mm particles, superficially porous silica all combined with elevated temperature and pressure – are discussed in detail and method conversions are attempted practically.
Instrumentation is also taken into account and the various approaches to Fast HPLC using conventional pressure as well as Ultra High Pressure system hardware and the importance of extra column volume and hysteresis effects are also discussed and demonstrated. The overall aim of the training is to enable clients to speed up existing separations or to develop novel ‘Fast’ HPLC separations.
