The invention relates to an analysis device with a multi-way valve which is connected, via a pump line, to a bidirectional pump. A storage member for storing a sample fed to it and any auxiliary substances is accommodated in the pump line. The multi-way valve is connected, via two separate discharge lines, to an analysis vessel. The multi-way valve and the pump are controlled, with the aid of a microprocessor, in such a manner that the following steps are carried out: a. connecting a first feed line to the pump line via the multi-way valve, in order to feed sample to the storage member, b. using the pump to suck the sample into the storage member, c. connecting the pump line, via the multi-way valve, to a first discharge line which opens into the analysis vessel, d. feeding some of the sample present in the first storage member to the analysis vessel via the pump and via the first discharge line, e. connecting the pump line to the flushing line via the multi-way valve, f. discharging sample which has remained in the storage member via the flushing line by feeding the reactant to the multi-way valve until the multi-way valve is full of reactant, g. connecting the pump line, via the multi-way valve, to a second discharge line which opens into the analysis vessel, and h. introducing the reactant into the analysis vessel via the second discharge line. |
