WKT-V2 Karl Fischer Oven Moisture Measurement System

When measuring moisture with a Karl Fischer analyzer, most samples can be added directly to the generator cell/titration cell for simple, accurate testing. Some samples, however, cannot be added directly because their moisture is not released naturally or they undergo side reactions with the Karl Fischer reagent — for example powders, granules, pastes, and oxidizing inorganic salts.

For samples that cannot be added directly to the cell, pairing the WKT-V2 Karl Fischer oven for gas-phase extraction is the perfect solution. The sample is placed in a vial and moved onto the oven, heated to a specific temperature (up to 300˚C), and the moisture is extracted and carried into the cell by dry air or nitrogen, then measured perfectly.


VicoMeter at the Customer Site

The customer purchased the WKT-A9 Karl Fischer moisture titrator mainly to test lithium battery powder samples. After arriving at the customer's site, the VicoMeter technical engineer first installed the WKT-A9 and let the instrument equilibrate, then began installing the WKT-V1. After installation, he demonstrated sample testing for the customer using 130° with a 150S delay. The results were very close to those from the customer's original Mitsubishi instrument, and the customer was very satisfied with the results.

Which Samples Can a Karl Fischer Moisture Analyzer Test? Which Samples Can a Karl Fischer Moisture Analyzer Test?

As a classic moisture determination method, Karl Fischer titration is suitable for measuring water in a wide range of organic and inorganic substances. Because compounds vary in their properties, they fall into two categories: those that can be analyzed directly and those that cannot.

Karl Fischer Moisture Analyzers Karl Fischer Moisture Analyzers

A Karl Fischer moisture analyzer is an instrument designed on the Karl Fischer method to measure moisture content in materials. It is also known as a Karl Fischer moisture meter, fully automatic Karl Fischer moisture titrator, intelligent Karl Fischer trace moisture analyzer, or Fischer-method moisture meter, and comes in two types: coulometric and volumetric (titrimetric).

What Calibration Standards and Verification Methods Are Available for Karl Fischer Moisture Determination? What Calibration Standards and Verification Methods Are Available for Karl Fischer Moisture Determination?

VicoMeter Karl Fischer moisture analyzers are typically calibrated and verified using standards such as methanol-water standard solutions, water-containing sodium tartrate, distilled (deionized or pure) water, and water-saturated toluene. This article introduces the calibration substances, calibration methods, and accuracy verification procedures commonly used with VicoMeter coulometric and volumetric Karl Fischer moisture analyzers.
