Customer Profile

G&W Electric purchased the VicoMeter WKT-A9 "Exquisite" coulometric Karl Fischer moisture analyzer. Using the coulometric Karl Fischer principle, the WKT-A9 rapidly determines trace moisture down to 0.001 ppm in solids, liquids and powders within one minute. The instrument features built-in printing, storage for 500 data sets, and real-time query and printing. Innovative guided prompts and a built-in electronic manual make operation simple. Compliant with multiple national and international moisture determination standards, the WKT-A9 includes eight moisture calculation formulas and six measurement methods for all industries, and is widely used in chemical, petroleum, pharmaceutical, power, food, research and testing sectors.

VicoMeter at the Customer Site

Upon arrival, the VicoMeter engineer first confirmed with the customer that no accessories were missing, then proceeded with the standard installation. After a smooth installation, reagent conditioning began: once the reagent was loaded, the engineer conditioned it with pure water and verified with 2 µL of pure water, obtaining 1956 µg—within the normal range of 1900–2100 µg. The engineer then demonstrated with the customer's sample. Using a 1 mL syringe with a No. 9 needle, he found the sample too viscous for the supplied needle, so the customer provided the larger-gauge needle they had used before, which injected the sample into the electrolytic cell easily. Per the customer's request, the sample was tested by the density method; results were repeatable and accurate.

Different samples require different syringes—choosing the right one makes all the difference.
