Guangzhou Tianmei Medical Technology Co., Ltd.
The customer purchased the VicoMeter WKT-A9 Precision Karl Fischer moisture analyzer and the matching WKT-V1 Karl Fischer oven. The WKT-A9 Karl Fischer moisture titrator is a coulometric Karl Fischer moisture titrator independently designed and developed by our company with proprietary intellectual property rights — a Karl Fischer moisture meter for mid-to-high-end applications.
Coulometric (coulometry) principle, ideal for trace-level testing; 5-inch color touchscreen with smart operation, automatic result calculation, and freely configurable sample IDs; complies with multiple national standards and suits virtually every industry.
8 moisture calculation formulas, 6 determination methods, and 8 end-point detection algorithms
Automatic drift compensation, automatic subtraction of ambient and background moisture, and self-diagnostic fault alerts
One-touch start for reliable results
Outstanding automation — connects seamlessly to the Karl Fischer oven for difficult samples
RS232 interface for connection to a PC, printer, PLC, or LIMS
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.
After arriving at the customer's site, the VicoMeter technical engineer first checked the accessory list with the customer and then began installation. Because the customer's samples are highly hygroscopic, the customer asked the engineer to install the instrument inside a glove box. The customer's samples are absorbable sutures — solid plastic threads — which cannot be measured directly with a Karl Fischer moisture analyzer and must be tested with a Karl Fischer oven. Since the thread-like samples cannot lie flat at the bottom of the sample vial, they must be cut into small sections for testing. Because the moisture content of the samples is very low, 10 sample pieces are needed for each test. The engineer and the customer each ran one test: the engineer's sample of 1.0324g gave a result of 203.1PPM, and the customer's sample of 1.1029g gave 228.5PPM. The test data were basically consistent with the customer's third-party test results.
