Method for metering powders and device for implementing the method

摘要

A method for metering powders as well as a powder metering device are described which are used in particular for preparing combinatorial material libraries. The powder metering device includes a metering element having a tubular supply vessel open on one end for taking up the powder to be metered and a plunger which is axially movable and which reversibly closes the end of the tubular supply vessel opposite the opening. To take up the powder, the opening of the metering element is first plunged with a predetermined force into a loose fill of the powder to be metered previously charged in a metering receiver.
