The Use of Test Kits in the Field and Laboratory

July 16, 2024
12:00pm - 1:30pm Eastern


Course Description:

It is not unusual to for laboratory analysts and field personnel to use analytical test kits. They are especially popular with water and wastewater operators who may not have a laboratory background. Test kits are created to be simple to use. Because of this, it is easy to overlook whether the test kit is appropriate for the parameter being analyzed and whether the test kit meets requirements for NELAP accreditation.

This presentation will discuss how - and when - test kits can be used in the environmental lab. It will also discuss how to consistently produce accurate and reliable results when using test kits, whether results will be used for regulatory purposes or for process control.

Learning Objectives:

  • Knows how to determine if a test kit is appropriate for regulatory testing
  • Knows how test kits may differ from other published methods
  • Knows how to ensure that a test kit analysis meets the TNI Environmental Laboratory Standard
  • Be aware of additional quality control that may not be included in test kit instructions

Intended Audience:

This course is designed for Analysts, FSMO, Quality Managers, and Technical Managers.
