Measurement Uncertainty in Chemical Analysis

With tools to comply with ISO17025, USP Chapter 1220 and FDA expectations

Recorded, available with all reference material at any time

Order Button

Measurement and documentation of analytical uncertainty is a requirement of ISO 17025 and other quality chapters such as USP 1220. FDA regulations don't include the word uncertainty directly. However, having good information on the accuracy, possible errors and uncertainty of analytical  data is a prerequisite of Good Analytical Practices. And inspectors are familiar with measurement uncertainty because  FDA laboratories follow their procedures for measurement uncertainty to comply with their own regulations. Despite of the importance of measurement uncertainty laboratories have many questions.

Frequent questions are

  • What is the difference between inaccuracy, analytical error and measurement uncertainty
  • Why do we need to care about measurement uncertainty
  • What are specific requirements of ISO 17025
  • What exactly are the expectations of FDA inspectors
  • Do we also need uncertainty evaluation for standard and ad-hoc methods?
  • What are most common sources for uncertainty
  • How to best evaluate measurement uncertainty
  • Can we use intermediate precision for measurement uncertainty?
  • Is there any impact of uncertainty limits on out-of-specification results?
  • Are there any official acceptance limits for analytical measurement uncertainty
  • How to handle multiple uncertainties 
  • How to report measurement uncertainty estimates and results?

How does the audio seminar help:

Questions will be answered by Dr. Ludwig Huber in a new interactive audio seminar. During the seminar strategies and procedures will be presented on how to develop, document, maintain and update User Requirements. An extensive list of reference material like SOPs, templates and examples will help immediate and cost effective implementation.

During the interactive presentation you learn about:

  • Requirements and expectations from ISO 17025 and  FDA
  • Other official standards and guidelines
  • The importance of measurement uncertainty for the quality of analytical data
  • Analytical uncertainty vs. inaccuracy and error
  • Comparison of four alternative approaches
  • Identifying uncertainty sources
  • Setting specifications for uncertainty
  • The uncertainty measurement process from sampling to reporting: flow diagram
  • Example procedure for measurement uncertainty
  • Quantification of individual sources
  • Evaluation of uncertainty for ad-hoc methods
  • Combining multiple uncertainties
  • Reporting for ISO 17025 and FDA
  • Impact of uncertainty results on product specifications and out-of-specification results
