VicoMeter at the Customer Site

The customer mainly tests glycerol-based samples, which must be determined by the Karl Fischer method according to pharmacopoeia requirements. The A3 installation went smoothly. After installation, the VicoMeter technical engineer first performed verification with 2ul of deionized water: three verifications gave results of 1953ug, 1984ug, and 1966ug — stable, repeatable data all within the required range. After verification, the engineer tested the customer's sample, giving a moisture result of 0.219% — stable and accurate. After the test, the customer told the engineer that this type of sample does not need to be tested every day and asked whether there was a good way to save reagent. The engineer suggested storing the reaction vessel together with its electrodes in a sealed container, which reduces the reagent's contact with moisture and effectively extends its service life — reagent kept in a sealed environment can be stored much longer.
