摘要： The present disclosure relates to an automatic analyzer for determining a parameter of a sample fluid, including a dosing device comprising at least one dosing chamber, a first fluid flow path connecting a sample receiving vessel to the dosing chamber via a first pump, a tank containing a dilution medium, a second fluid flow path connecting the tank to the dosing chamber via a second pump, a measuring cell in communication with the dosing chamber via a third fluid flow path via a third pump, and a measuring and control system connected to and configured to control the pumps, wherein the first, second, and third fluid flow paths can selectively be blocked or unblocked by at least one valve unit and the measuring and control system is configured to control the at least one valve unit to block or unblock the first, second, and third flow paths.

摘要： The present disclosure relates to a method for metering a liquid into a wet chemistry analytical device wherein a specified volume of individual liquids is placed in a metering unit consisting of a metering container and at least one dose measuring device. During the filling of the metering container with the respective liquid, after the activation of the dose measuring device, an additional volume of the liquid is drawn into the metering tube beyond the position of the dose measuring device, wherein during this procedure and afterwards the status of the dose measuring device is checked, and a conclusion is drawn from this regarding the presence of an air bubble-free liquid in the metering tube.
