How to Implement an Effective and Compliant Procedure for Determining Detection and Quantitation Limits

Synopsis

The class reviews materials and techniques that laboratories, data users and assessors can use to successfully address the challenges of complying with the 2016 TNI Standard, and the 2017 EPA Method Detection Limit (MDL) procedure while implementing effective and scientifically sound practices for measuring sensitivity in environmental analysis.

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, "how does a small laboratory manage the process, and how do I reconcile this with the requirements of EPA's method detection limit.

The class describes how to apply the concepts method detection and quantitation to establishing laboratory practices that are meaningful, scientifically based and compliant with the TNI accreditation requirements. The presenter will focus on practical definition and use of these concepts, review of current EPA requirements, the 2016 TNI standard, actual real-life options and considerations and suggested processes for evaluating sensitivity and reporting systems.

Learning Objectives

  • Understand the basic procedure for calculating an MDL according to 40 CFR Part 136.
  • Understand the basic requirements of the 2016 TNI Standard for LOD and LOQ.
  • Understand the key differences between the EPA MDL and the TNI LOD.
  • Understand how to analytically verify the LOQ and calculate a MDL/LOD.
  •  Understand how to periodically reverify the LOQ and recalculate the MDL/LOD
  • Be able to assess laboratories compliance with both the EPA procedure and TNI requirements.

Group rates are available: Each purchased training course is to be viewed by only one student. If you would like multiple viewers, separate purchases must be made. A group rate of $303 for TNI members or $385 for non-members is available for groups of 6-10 students at a single location.

No certificates are automatically provided with this training. A Certificate of Completion (CoC) ($30 per person) or Certificate of Attendance (CoA) ($20 per person) may be purchased. A passing score of at least 70% must be received on the exam in order to receive CEUs and a CoC. Scores of less than 70% will receive a Certificate of Attendance at no reduced fee. For a CoA you will not need to take the quiz and you will not receive CEUs. To receive your certificate, contact Paul Junio at [email protected] with date of purchase and date of training completion.
