Quality Assurance of Chemical Measurements

Upcoming Dates

PACS Course Number 70

9 AM to 5 PM

The course instructor is Dr. Henry Nowicki. This course provides an introduction to methods designed to help provide analytical information that is useful and defensible, legally and technically to your data users. Laboratory quality control and assessment of chemical measurement data makes good professional and business sense. Good laboratory practices provide happy and continuing clientele, risk reduction, professionally motivated staff and confidence in the lab data. This two-day short course is designed for managers, chemists and technicians who have responsibility for the quality assurance of laboratory data. The text by Dr. John Taylor, "Quality Assurance of Chemical Measurements", should be purchased and studied to prepare for this course. Call Lewis Publishing to purchase this book at (800) 272-7737. An agenda for this course is below.

The course content will include: approaches to quality assurance, planning, measurement considered as a process, basic statistical tools, evaluation of analytical data, modeling, sampling, selection of capital equipment, selection of methodology, calibration, quality control, control charts, quality assessment, traceability, use of reference materials, reporting analytical results, troubleshooting, laboratory certification, and the design, implementation and monitoring of quality assurance programs. Materials presented in Dr. Taylor’s book will be the focus of this course and the practical experiences of the instructor and your interests. The instructor has worked in academic, industrial and government labs where the results required strong use of quality assurance.
