E22-18: How to Develop Validated HPLC Methods: Rational Design with Practical Statistics & Troubleshooting

One-Day Course
Tuesday, Nov. 15; 8:30am – 5:00pm

Dr. Brian A. Bidlingmeyer, Analytical Acumen Inc., Wilmington, DE
Dr. Stanley N. Deming, Statistical Designs, Houston, TX

This course offers practical training for the practicing scientist. The course outlines a straightforward, iterative process to integrate method development and validation activities. The course discusses how to carry out routine maintenance to prevent loss of validation, and how to set diagnostics to recognize behavior that requires troubleshooting. Consult with instructors who have many years of experience in industry and academe.  Leave with a strategy for developing your own validated methods

This one-day course is intended for individuals who will develop and/or carry out quantitative HPLC analyses. Laboratory managers, supervisors, analysts, chemists, biologists, engineers and technicians who are responsible for the continual use of validated HPLC methods should attend this course.
