WHO SHOULD ATTEND:

Typical Industries: Pharmaceutical, Biotechnology, Clinical, Forensic, Environmental, Food
Job Functions: Analytical Chemists, Scientists, Technicians, Analysts, Supervisors, Auditors
Departments: QA/QC, Manufacturing Support, Metrology, Calibration, Qualification, Validation

LEARNING OBJECTIVES:

- Become confident in recognizing the difference between measurement error and uncertainty
- Acquire an understanding of the value of measurement uncertainty in chemical analysis
- Demonstrate a competence in estimating the uncertainty of analytical measurement results

COURSE OUTLINE:

Module 1 – Introduction to Measurement Uncertainty
- Principles, concepts and importance of measurement uncertainty
- Role of measurement uncertainty in ISO/IEC 17025 accreditation
- Overview of approaches to estimation of measurement uncertainty

Module 2 –Simplified Procedure for Estimation of Measurement Uncertainty by the ISO Approach
- Identification of sources of uncertainty
- Quantification and combination of individual sources of uncertainty
- Calculation and expression of expanded uncertainty

Module 3 – Examples of Estimation of Measurement Uncertainty
- Reference material standards for UV/VIS absorption spectrophotometer qualification
- Calibration standard for atomic spectrochemical analysis

COURSE DESCRIPTION:

Measurement uncertainty is an important metrological concept underpinning the quality and acceptance of calibration and test results in the modern analytical laboratory. Its role in analytical chemistry and related disciplines is expected to increase as global quality requirements become entrenched. Already it is a technical requirement of ISO/IEC 17025 accreditation. This course provides an introduction to measurement uncertainty, how it may be estimated, and why it impacts the laboratory’s competence and reputation in chemical analysis.

COURSE DIRECTOR BIO:

Jerry D. Messman holds a Ph.D. degree in analytical chemistry from the University of Maryland. He conducted his doctoral research at the National Bureau of Standards (NBS), now known as the National Institute of Standards and Technology (NIST). During his early years at NBS, Jerry also participated in the analytical certification of metal concentrations in various types of matrix-laden Standard Reference Materials (SRMs) used for quality control, method validation and metrological traceability in the analytical laboratory. From 1988 to 1992, he directed all NIST technical activities involving the production, certification, and recertification of UV/VIS spectrophotometric SRM transfer measurement artifacts. For the past 15 years, Jerry has served as Managing Director and Senior Scientist of Stranaska Scientific LLC, a research and development company specializing in analytical UV/VIS absorption spectrophotometric metrology.

Jerry is an elected member of CITAC, an acronym for the Cooperation on International Traceability in Analytical Chemistry. Also, Jerry has recently been appointed to the Clinical and Laboratory Standards Institute (CLSI) Subcommittee on Metrological Traceability and it's Implementation of the Committee on Clinical Chemistry and Toxicology.
