E25: Data Analysis Skills for Chromatographers

One-Day Course
Date to be announced; 8:30am – 5:00pm
Dr. Merlin Bicking, ACCTA, Inc., St. Paul, MN

COURSE DESCRIPTION
We all need to analyze our acquired HPLC data, but there is surprisingly little information and training available. This course will help new and intermediate-level analysts get started and become more efficient with their Data Analysis activities. We focus on the three critical aspects of chromatographic Data Analysis – examining your chromatography, integrating the peaks of interest, and using calibration standards to calculate the quantities of our analytes. Serious analytical errors can result from a failure to follow best practices in any of these three activities. Real-world examples are used throughout this course to help teach these concepts.

WHO SHOULD ATTEND 
New and intermediate-level analysts will see the most benefit from this course. In addition, anyone who reviews chromatography data and results should also understand these issues. Supervisory staff can benefit from a deeper understanding of the Data Analysis process.
