摘要： The present application relates to a method for operating a dosing device with a control unit and a dosing unit. The dosing unit has a cannula with a first volume and a tip, and also a sampling container fluidically connected to the cannula. In a first step, the dosing unit is moved linearly at a predetermined speed in a first direction along an axis, such that the cannula is moved into a vessel containing at least one liquid. At the same time, fluid is aspirated constantly through the cannula with a predetermined volumetric flow by a pump device. At least one optical parameter of the aspirated fluid is measured by at least one optical sensor, which is arranged between the cannula and the sampling container. When a change of the at least one optical parameter is detected, a first position of the dosing unit on the axis is stored by the control unit and the movement of the dosing unit is interrupted. The control unit then calculates a second position of the dosing unit on the axis, at which second position the tip of the cannula has penetrated a first phase boundary, in particular upon immersion into the liquid. The calculation is performed on the basis of the first position, the predetermined speed, the first volume and the predetermined volumetric flow.

摘要： In a method for analysing a sample, a plurality of sample preparation devices and an automatic analytic device for analysing the sample are used, wherein said plurality of sample preparation devices and the automatic analytic device are connected to each other by a data processing unit in order to receive, process and send data from and/or to each one of said sample preparation devices and the automatic analytic device. The method comprises the steps of preparing a first portion of the sample by a first sample preparation device; analysing said first portion by the automatic analytic device in order to get a first result; comparing the first result with a value dependent decision criteria to get a first decision value or a second decision value by the data processing unit. If the decision value is the second decision value, a second portion of the same sample by the second sample preparation device is prepared and analysed by the automatic analytic device in order to get a second result. The second result is compared with said value dependent decision criteria value to get the first decision value or the second decision value by the data process unit. The preceding steps are repeated until the first decision value is obtained.
