Customer Profile

Siya Lubricants (Shanghai) Co., Ltd. purchased the VicoMeter WKT-A9 'Precision' Karl Fischer moisture analyzer with the matching WKT-V2 Karl Fischer oven auxiliary heating unit. The WKT-A9 'Precision' Karl Fischer moisture analyzer uses the coulometric Karl Fischer principle to determine moisture content in samples, quickly measuring moisture in liquids, solids and gases, and is widely used in chemicals, pharmaceuticals, plastics, food, lithium batteries, testing, petroleum, electric power, pesticides, and academic and research fields. For samples that cannot be added directly to the electrolytic cell, gas phase extraction is the perfect solution: the sample is placed in a sample boat/vial, moved into the heating chamber of the WKT-V2 Karl Fischer oven, and heated to a specific temperature (up to 300°C); dry air or nitrogen extracts the moisture and transfers it to the titration cell, where the Karl Fischer analyzer determines the sample's moisture concentration.

WKT-V2 Karl Fischer Oven Moisture Measurement System

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 mainly tests moisture in oil products. Normally, the WKT-A9 alone would suffice for testing oil samples. However, the customer produces many oil products with viscosities ranging from 32 mm²/s to 2000 mm²/s. With the WKT-A9 alone, sample injection becomes very difficult above 300 mm²/s, and such viscous samples also dissolve poorly in the reagent. For oils with viscosity above 300 mm²/s, we therefore recommend testing with the WKT-V1-A9. After installing the instrument on site, the VicoMeter technical engineer demonstrated the full range of oil samples from 32 mm²/s to 2000 mm²/s and let the customer perform several demonstration tests. When testing 32-300 mm²/s samples directly with the WKT-A9, the customer at first could not time the injection well and needed several corrections before operating correctly; testing 300-2000 mm²/s oil samples with the WKT-V1-A9 went smoothly.
