Event Overview:

HPLC mobile phase is at the heart of an HPLC method. It is used to control the retention of analytes and, if chosen or prepared incorrectly, can cause a myriad of problems such as extra peaks, unexplained retention time shifts, and system contamination. These top 20 tips for successfully designing and preparing a mobile phase will help individuals avoid many of the common pitfalls that occur while using this method.

Topics Covered:

• Correctly controlling pH using buffers
• Eluent mixing
• Filtration and degassing
• Reagent quality
• Mobile phase shelf life
• Impact of mobile phase in gradient HPLC
• System flushing
• Common mistakes to avoid

Colin Towers
Senior Technical Support Chemist
Element

After completing a degree in pharmacy, Colin Towers pursued a career in analytical chemistry. Following three years performing routine testing and three years instrument maintenance and calibration, he moved into a role as a method development and validation specialist in contract research. Gaining 11 years’ experience in developing methods for HPLC, LC-MS, GC, GC-MS and SPE in a high throughput commercial environment, this was supplemented by three years lecturing in forensic analytical toxicology and a further three years working as a community pharmacist. Towers has now been with Crawford Scientific for eight years as a technical specialist, consultant, and trainer.

Dr. Dawn Watson
CHROMacademy Product Manager
