Customer Profile

The customer purchased the VicoMeter WKT-A9 "Exquisite" Karl Fischer moisture analyzer together with the WKT-V1 Karl Fischer oven. Using the coulometric Karl Fischer principle, the WKT-A9 rapidly determines trace moisture down to 0.001 ppm in solids, liquids and powders within one minute. The instrument features built-in printing, storage for 500 data sets, and real-time query and printing. Innovative guided prompts and a built-in electronic manual make operation simple. Compliant with multiple national and international moisture determination standards, the WKT-A9 includes eight moisture calculation formulas and six measurement methods for all industries, and is widely used in chemical, petroleum, pharmaceutical, power, food, research and testing sectors.

WKT-V2 Karl Fischer Oven Moisture Measurement System

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 mainly tests the moisture of lithium battery powders and electrolyte. Because the instrument is used for finished-product quality inspection rather than research, environmental requirements were not stringent, so it was installed normally in the customer's laboratory rather than in a glove box. At installation, the laboratory temperature was 19°C with 46% humidity, meeting installation requirements.

Upon arrival, the VicoMeter engineer first checked the accessories with the customer, then began installation and commissioning. Afterwards, engineer and customer ran several tests with lithium battery powder and electrolyte from the customer's production line. The powder results—189 ppm, 194 ppm and 197 ppm—were within the customer's expected range; the electrolyte results—45 ppm, 51 ppm and 47 ppm—were stable and within the customer's QC limits. VicoMeter's instrument fully met the customer's quality-control requirements.
