WKT-A3 'Vision' Karl Fischer Trace Moisture Analyzer

Qigao Instruments purchased the VicoMeter WKT-A3 'Vision' Karl Fischer trace moisture analyzer. The WKT-A3 'Vision' uses the coulometric Karl Fischer principle to quickly determine trace moisture in samples, measuring water content as low as 1 ppm and determining trace moisture in solids, liquids and powders within 1 minute, with a built-in printer. The WKT-A3 complies with multiple national and international moisture determination standards, with eight built-in moisture calculation formulas and six measurement methods to meet the moisture determination needs of various industries, and is widely used in chemicals, petroleum, pharmaceuticals, electric power, food, research, testing and other industries.

VicoMeter at the Customer Site

Before purchasing the VicoMeter instrument, the customer sent a sample—a highly viscous material. During testing, it was found that after the experiment the sample tended to stick to both electrodes and was very difficult to clean. The VicoMeter technical engineer used methanol, xylene and ultrasonic cleaning, among other methods, to clean the two electrodes. Before the business trip, the engineer had brainstormed countless cleaning methods.

After the VicoMeter technical engineer installed the instrument on site and began the demonstration, the customer brought the samples they wanted to test. It turned out that what the customer needed to test was not the final product but some raw materials, which were not sticky.

During installation, while equilibrating the reagent, the VicoMeter technical engineer found that the instrument could not reach equilibrium no matter what—the color in the electrolytic electrode kept darkening while the reagent in the titration cell showed no change. The engineer judged that the electrodes might be reversed, reversed the electrolytic electrode connections, and the problem was easily solved.

Generally, those who contact us before purchasing are procurement staff, who may not fully understand the samples to be tested—perhaps not even knowing what the sample is, only that moisture must be measured. VicoMeter technical engineers therefore hope to communicate with customers in as much detail as possible: the more detailed the communication, the clearer the customer's needs, and the better the solution we can develop.
