Brown Bag 2: Theoretical and Practical Consideration for Establishing Sensitivity of Measurements


Understanding and Implementing LOD and LOQ and their relationship to MDL and PQL

This 3-hour interactive webinar 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 measuring sensitivity in environmental analysis. A strong focus will be on understanding the theory, interrelationships and practical considerations associated with LOD, LOQ, MDL and concepts established by Lloyd Curie.

Establishing and maintaining a practical approach for the TNI requirements for LOD/LOQ is one of the most confusing and complicated challenges for laboratory management. A good deal of the confusion centers on "what is needed"," why is it needed" , "how does a small laboratory manage the paperwork" and" how do I reconcile this with the requirements of EPA's method detection limit and the alphabet soup of differing reporting requirements". This workshop explores the origins of method detection and quantitation, the theory behind these concepts and most importantly how to apply these concepts to establishing laboratory practices that are meaningful, scientifically based and compliant with the TNI accreditation requirements.

This workshop is intended to be interactive. This 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 and suggested processes for evaluating sensitivity and reporting systems. Questions are encouraged and welcome. Several options for participants to provide feedback, including their own experiences, solutions and frustrations will be provided.
