Karl Fischer Titration Guide, Part 3 — Sampling Techniques covers important rules and guidelines for drawing samples to determine water content according to Karl Fischer. |
Taking the right sample in the right way is a prerequisite to obtaining accurate and reliable results. In the case of water content determination, avoiding water absorption from atmospheric moisture, sampling tools or sample vials and vessels is a paramount sampling objective.
Different sampling techniques have been developed to accommodate the varying nature of samples since the first Karl Fischer titrations were carried out in 1935.
This guide explains some important rules and guidelines for drawing samples to determine water content according to Karl Fischer. Our tips and tricks incorporate the experience of METTLER TOLEDO’s application chemists and are well proven through daily practice and application.
Download the Titration Guide and rely on good sampling techniques as the starting point of reliable results.
