Customer Profile

Nantong Shankou Precision Electromechanical purchased the VicoMeter WKT-A9 Precision Karl Fischer moisture analyzer. The VicoMeter WKT-A9 Precision Karl Fischer trace moisture analyzer uses the coulometric Karl Fischer (coulometry) principle to rapidly measure trace moisture in samples, detecting water down to 0.001 ppm and determining trace moisture in solids, liquids, and powders within one minute. The built-in printer and storage for 500 data sets allow real-time query and printout. Innovative guided prompts and a built-in e-manual make operation simple. The WKT-A9 complies with multiple national and international moisture standards and provides eight built-in moisture calculation formulas and six determination methods to meet the moisture testing needs of every industry. Widely used in chemicals, petroleum, pharmaceuticals, power, food, research, and testing, it is a Karl Fischer moisture analyzer built for mid-to-high-end applications.

VicoMeter at the Customer Site

When the VicoMeter service engineer arrived on site, the ambient humidity was very high — as much as 78%. Following the engineer's advice, the customer closed the doors and windows and switched on the air-conditioning dehumidifier; after about an hour the laboratory humidity dropped to 55%, meeting the instrument's installation requirements.

After installation, the engineer began testing the customer's samples — an additive used in cleaning agents with low moisture content, no aldehydes or ketones, and neutral pH. A standard pyridine-free coulometric Karl Fischer reagent was therefore selected. Because the sample's water content was low, a 2 mL syringe was used, since a larger sample volume is needed to guarantee accurate data. A 1.9856 g sample gave 102 ppm and a 2.0152 g sample gave 108 ppm — stable, repeatable results that fully satisfied the customer.

When dealing with samples containing very little water, appropriately increasing the sample size makes the results more stable and the data more reliable.
