Quality-by-Design (QbD): A New Paradigm for the Analytical Laboratory II:
Design of Experiments (DOE) for Analytical Chemists
One-Day Course
Dr. Zenaida Otero Gephardt, Rowan University, Glassboro, NJ
COURSE DESCRIPTION
Design of Experiments (DOE) is one of the cornerstones of quality-by-design (QbD) in the laboratory. Optimization of experimental design techniques offers the advantage of minimizing the number of experiments required in the laboratory. This improves the efficiency of the laboratory staff and reduces the cost of operation. Experimental design techniques often yield better data, and results that are more meaningful and easier to interpret. Critical quality attributes (CQA) are identified and effects of critical process parameters (CPP) are ascertained and quantified in the most efficient manner. In addition, experimental design allows for optimization of continuous improvement techniques in the laboratory. Many design techniques are simple to use and only require a calculator or spreadsheet software. Experimental design techniques allow laboratory staff to focus on experimental development and to mainstream laboratory operations and regulatory matters. This course will provide participants with analysis tools they can immediately use in their laboratories including an introduction to available experimental design software. Practical applications will be used to illustrate experimental designs throughout the course.
WHO SHOULD ATTEND
Analytical chemists at all levels will benefit from this course. Laboratory supervisors and technical personnel involved in data analysis and reporting will also benefit.
