Measurement Uncertainty in Analytical Chemistry

 
  June 21, 2010  
     
 
CfPA - The Center for Professional Advancement, 90 Minute Accredited Online Training
September 23, 2010 at 11:00 a.m.–12:30 p.m. (ET)


Who Should Attend
This course will benefit professionals in the following industries: Pharmaceutical, Biotechnology, Clinical, Forensic, Environmental and Food.

It is intended for those whose job functions include:Analytical Chemists, Scientists, Technicians, Analysts, Supervisors and Auditors and those working within the areas of QA/QC, Manufacturing Support, Metrology, Calibration, Qualification or Validation

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 90-minute accredited online training 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.

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

Invited Speakers: Jerry D. Messman, Ph.D, Managing Director/Sr. Scientist, Stranaska Scientific LLC

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, Dr. Messman 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, Dr. Messman 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. He is an elected member of CITAC, an acronym for the Cooperation on International Traceability in Analytical Chemistry.
