Calibration, validation and control of analytical instruments and reagents are central requirements in regular quality management systems. In the case of Karl Fischer titration, the most widely used method for water determination, a known amount of water is required. How we administer this water is the challenge.

In this webinar, we’ll discuss how sample size ties into standard selection, along with the various options available for the volumetric and coulometric KF systems. We’ll also discuss how the water standards may be used to help verify the results of a sample.

During this webinar you will learn about:

  • the importance of sample size with regard to standard selection
  • the available standards for the volumetric and coulometric systems
  • proper handling techniques for the water standards
  • the use of water standards to verify results
