Application Case of the WKT-A9 Karl Fischer Moisture Titrator at Shanghai Benyou New Materials Technology — VicoMeter | Jiangsu Victor Instrument Meter Co., Ltd.

VicoMeter On-site Training

Customer Profile

Benyou Technology purchased the VicoMeter WKT-A9 Karl Fischer moisture analyzer with the matching WKT-V2 Karl Fischer oven. The WKT-A9 is a coulometric Karl Fischer titrator of our own proprietary design. The WKT-V2 is the fourth-generation Karl Fischer oven from Jiangsu Victor Instrument Meter Co., Ltd., with a more user-friendly, streamlined touch OS. Paired with our dedicated moisture analyzer, the VicoMeter 'volcano' series WKT-V2 suits moisture determination of insoluble samples (battery materials, plastics and rubber, lubricants and greases, pharmaceutical materials, new materials, moisture-absorbing and volatile-component samples) and is widely successful in 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.

VicoMeter at the Customer Site

The customer had previously used another brand's coulometric KF analyzer for about six months before setting it aside. Familiar with the principle and operation, they operated it proficiently after only a brief explanation from the VicoMeter engineer.

The engineer demonstrated with the customer's actual samples. As the customer had always used the volumetric method, the engineer compared the pros and cons of gravimetric vs. volumetric approaches; with an analytical balance on hand, the customer chose the gravimetric method: fit the No. 9 needle, draw the sample, tare on the balance, press start, inject, reweigh, enter the weight, and read the result. Repeated runs were stable and repeatable, and the customer was highly satisfied with the instrument and service.

Providing customers with the most professional moisture analysis solutions has always been VicoMeter's pursuit.
