about moisture: Loss of weight and Karl Fischer’s chemical reaction. The most commonly used methods for for testing plastics and polymers using either a Moisture Analyzer or Karl Fischer titration, respectively. Each method offers an easy way to execute the tests and delivers results quickly. Chapters 3 and 4 focus on these methods.The oven method (loss on drying) or Karl Fischer titration is usually used as the reference procedure. In such cases, the aim is to obtain the same results with the halogen moisture analyzer as with the reference procedure (or for the deviation from the reference value to be known and reproducible).
Karl-Fischer-Moisture-Analyzer.com Karl Fischer Moisture Analysis for measuring water in crude oil. Measuring the percentage of water in crude oil (BS&W) is an important need in many applications throughout the production and transportation process. It is particularly important in marine and truck custody transfer applications where small .
Karl Fischer Titrators and Moisture Analyzers utilize advanced technology such as the Karl Fischer volumetric method to swiftly determine moisture content in various samples. With features like automatic reagent balance, touch functionality, and high precision components such as dual platinum electrodes, our titrators and analyzers ensure accurate results with minimal . In these cases, we use the Karl Fischer Titration method—also known as Moisture by Karl Fischer (MKF) test. During the Karl Fischer Titration test, water is directly consumed by reaction with the titrant within the conditions of the reaction vessel. Thus Karl Fischer Titration is more selective for water than the traditional oven heating method.A Karl Fischer (KF) coulometric titrator is one of the most accurate methods. Unlike other techniques, it can trace low levels of free, emulsified and dissolved (which cannot be detected with other methods such as a crackle test). .
