Customer Profile

The customer purchased the VicoMeter WKT-A9 Advanced Karl Fischer moisture analyzer with the matching WKT-V1 Karl Fischer oven. Working on the Karl Fischer coulometric principle, it rapidly determines trace moisture down to 0.001 ppm within 1 minute for solids, liquids, and powders, with a built-in printer storing 500 data sets for real-time query and printing. Navigation-style prompts and a built-in e-manual keep operation simple. Complying with multiple national and international standards, its 8 moisture formulas and 6 methods serve chemical, petroleum, pharmaceutical, power, food, research, and testing industries — a Karl Fischer meter for mid-to-high-end applications.

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

As the WKT-V1 was pre-stocked with accessories ready, assembly and shipment were completed quickly. We shipped immediately after Ruijie's order, and installation went smoothly thanks to the customer's preparation. During commissioning, 2 µl of pure water read 1956 µg — within range — but 0.2 µl and customer samples read high. After the customer replaced the nitrogen, data improved but low-moisture samples still erred; after a meeting with our chief engineer, the molecular sieve was dried and the data normalized.

This issue occurs mainly because the molecular sieve has been stored at the company for too long and has absorbed moisture from the air, causing abnormal test data. VicoMeter is committed to providing customers with the most professional service; as long as the customer provides the specific conditions of the installation site, we can offer the optimal solution.

Jiangsu Ruijie Plastic Pipes & Fittings

Founded in 1998 as a China–New Zealand joint venture, Jiangsu Ruijie Plastic Pipes & Fittings Co., Ltd. became wholly state-owned in 2008 after the Chinese shareholders acquired the foreign shares (approved by the Huai'an SASAC). First in China to introduce imported technology for new PE/PPR water-supply pipes, it now makes PE/PPR pipes and fittings, MPP cable conduit, PERT floor-heating pipes, gas pipes, steel-reinforced PE spiral corrugated pipes, HDPE double-wall corrugated pipes, and U-PVC wire conduit, with ISO9001 and ISO14001 certification — a high-tech enterprise integrating trade, R&D, production, sales, installation, and service.
