Abstract
A method for the preparation of samples by means of a dosage-dispensing device, a weighing system with a load receiver, a processor unit, a memory unit, and an exchangeable dosage-dispensing unit. A target container is set on the load receiver. The dosage-dispensing unit and/or the target container includes electrically insulating material. The dosage-dispensing unit has the capability to change positions relative to the load receiver. While the dosage-dispensing unit is in a first position and a target container is on the load receiver, a starting weight value is determined, the dosage-dispensing unit is brought into a second position, a dosage-dispensing cycle delivers a dosage material in a predefined amount from the dosage-dispensing unit into the target container by means of the processor unit, the dosage-dispensing unit is brought into the first position, and while the dosage-dispensing unit is at rest in the first position, an ending weight value is determined.
