Customer Profile

The customer purchased the VicoMeter WKT-A9 'Exquisite' Karl Fischer Moisture Analyzer together with the matching WKT-V1 Karl Fischer oven. Based on the coulometric Karl Fischer principle, the VicoMeter WKT-A9 'Exquisite' trace moisture analyzer rapidly determines trace moisture in samples down to 0.001ppm, and can measure trace moisture in solids, liquids, and powders within 1 minute. The instrument features a built-in printer and can store 500 sets of data for real-time query and printing. Innovative navigation-style prompts and a built-in electronic manual make operation effortless. Complying with multiple national and international moisture determination standards, the WKT-A9 includes eight built-in moisture calculation formulas and six determination methods to meet the needs of various industries. It is widely used in the chemical, petroleum, pharmaceutical, power, food, research, and testing industries, making it a Karl Fischer moisture analyzer for mid-to-high-end applications.

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

When the VicoMeter technical engineer went to install the instrument, the customer's production line and laboratory had not yet been fully renovated. At the customer's request, the engineer first installed the instrument in one of their small rooms; once the laboratory renovation is complete, the customer will move the instrument into the laboratory themselves.

The customer mainly tests a non-absorbable medical suture, whose moisture content has a significant impact on product shelf life, making moisture testing very important. After arriving on site, the VicoMeter technical engineer first checked the packing list with the customer, then began installation, which went smoothly, followed directly by a demonstration test. Because the customer's samples have a low density, three strands of thread need to be cut for each test. To ensure data accuracy, the engineer cut 10 strands and ran three tests, with results of 1.12%, 1.13%, and 1.09%. The results showed small error and accurate values — the instrument can measure the moisture of the customer's samples accurately and quickly, and the customer was very satisfied with the test results.
