Shandong Zhushi Pharmaceutical Group
Shandong Zhushi Pharmaceutical Group purchased the VicoMeter WKT-A9 Karl Fischer Moisture Analyzer together with the matching WKT-V2 Karl Fischer oven. The WKT-A9 Karl Fischer moisture titrator is a coulometric Karl Fischer moisture titrator designed and developed in-house with independent intellectual property rights. The WKT-V2 Karl Fischer oven is the fourth-generation Karl Fischer oven refined through multiple improvements by Jiangsu Victor Instrument Meter Co., Ltd., featuring a more user-friendly and streamlined touch operating system. Paired with our dedicated moisture analyzer, the VicoMeter 'Volcano' series WKT-V2 Karl Fischer oven is suitable for moisture determination of all kinds of insoluble samples (battery materials, plastics and rubber, lubricating greases, pharmaceutical materials, new materials, moisture-regain-prone samples, and samples with volatile components), and has been well applied in the plastics, battery, new materials, medical, and electronics industries!
WKT-A9 Karl Fischer Trace Moisture Analyzer Coulometric
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
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.
Shandong Zhushi Pharmaceutical Group purchased the VicoMeter Karl Fischer moisture analyzer mainly to test moisture in medical sutures. According to the customer's industry standard YY 1116-2020, testing medical sutures requires a coulometric Karl Fischer moisture analyzer and a Karl Fischer oven.
The customer had essentially completed the instrument assembly before the VicoMeter technical engineer arrived. Upon arrival, the engineer first inspected the customer's installation and found it generally fine, though various small details — such as the instrument's airtightness — were not done well enough; the engineer fixed all of these issues one by one. The engineer then standardized the instrument with pure water: first the A9 was equilibrated, then the V2 was connected to the A9. After the instrument equilibrated again, 2ul of pure water was injected into the sample boat, giving a result of 1986ug. The customer was very satisfied. The customer then brought out their sample; the engineer set the Karl Fischer oven to 140℃ with a delay time of 150S and ran the test, giving a result of 1121PPM. Since sampling was not performed inside a glove box, the result was within the customer's acceptable range.
