Workshop Excellence Webinar Series
Practical Implementation of Quality Assurance and Accreditation Requirements

Method Selection and Validation
An Essential Component of the Measurement Process

Who Should Attend?

  • Data Users
  • Laboratory Management
  • Quality Assurance and Technical Staff
  • Assessors

This 2-hour interactive webcast reviews materials and techniques that laboratories, data users and assessors can use to successfully address the challenges of complying with the TNI Standard, and the 2012 EPA Method Update Rule ( MUR) while implementing effective and scientifically sound practices for environmental analysis. A strong focus is on understanding some of the background, theory and practical considerations associated with selecting and validating the proper test methods to be used to generate data of known and documented quality that is scientifically sound and meets accreditation standards.

The method selection and validation requirements in the TNI EL Standard tend to very confusing to laboratory managers and assessors. A good deal of the confusion centers on "what is needed," "why is it needed" and "how does this apply to my small laboratory." This workshop explores the "life cycle of measurement analysis" and the part that proper selection of test methods plays in the overall generation of data of know and documented quality. This session exposes participants to a body of knowledge on methods and options as well as the practical considerations and benefits to proper validation of methods uses.

The presenters will focus on practical definition and use of these concepts, review of current EPA requirements, the 2009 TNI standard, actual real life options and considerations as well as documenting and retaining validation data.
