Quality control is not only an issue at the end of production, but is also used for monitoring the entire process. Zinsser Analytic is offering a robotic workbench, Calli QC, linking sample preparation to analytical measurement. The samples, which can be introduced continuously, are placed on the instrument on arrival from production and prepared for analytical measurement according to the user's requirements. They are weighed, diluted, heated, vortexed, filtered etc. before being transferred to the analyser. A large range of modules is available for the sample preparation process, such as handling of liquids, powders and viscous media. Barcode control ensures the tracking of the individual samples throughout the entire process.
