Abstract:
An analysis device (1) comprising:an analysis vessel (16);only a single pump (13, 25);a multi-way valve (5) connected to said pump via a pump line (9);a storage member (10) positioned in said pump line intermediate said multi-way valve and said pump;a first discharge line (6) and a second discharge line (7), both of said first and second discharge lines connected to said multi-way valve and connectable to said analysis vessel;a first feed line (4) connected to said multi-way valve, for feeding a sample to be analyzed to said multi-way valve;a second feed line (14, 26) connected to said multi-way valve or to said pump for feeding a reactant to said multi-way valve;a flushing line (8) connected to said multi-way valve;an operating device (20) operatively connected to and controlling said pump and said multi-way valve, said multi-way valve being configurable to place said first and second discharge lines, said first feed line, and said flushing line in fluid communication with said pump line via said multi-way valve,wherein no other elements but said storage member are positioned in said pump line for receiving the sample to be analyzed, andwherein said operating device is designed and operable to successively receive the sample in said storage member, transfer the sample, via said first discharge line, from said storage member into said analysis vessel and transfer the reactant, via said second discharge line, into said analysis vessel.
