VicoMeter at the Customer Site

The customer purchased a VicoMeter Karl Fischer moisture analyzer mainly to test the moisture content of methanol, one of their raw materials, and the moisture content of some gases. However, when the VicoMeter technical engineer arrived at the customer's site, he found that the customer's small gas cylinder, large-range high-precision balance, and dedicated gas sampling needle were not ready, so he could only demonstrate the moisture testing method for methanol and was unable to demonstrate the testing method for gases.

On arrival, the engineer checked the packing list with the customer and installed the instrument, then verified it with pure water at three points — 0.1 μL, 0.5 μL, and 2 μL — all within the qualified range. The engineer then ran two tests on the customer's methanol sample, getting 197 ppm and 186 ppm, while the customer's operator ran two more, getting 201 ppm and 193 ppm — four highly repeatable, accurate results. After the liquid-sample tests, the engineer discussed gas-sample procedures with the customer's technician, including the choice of balance and gas cylinder: for gas testing, choose a high-precision, large-range balance and the smallest practical gas cylinder. With that, the commissioning concluded; any further questions would be handled online, which the customer understood.
