The invention relates to a process analyzer (10) comprising a base module (14) and a replaceable cartridge module (12).n n n The base module (14) has a pump drive (16, 16 ') and an analyte sensor (20) without fluidic measuring path (60). The cartridge module (12) has a liquid storage tank (40, 41), a non-driven pumping mimic (36, 36 '), which pumps the liquid from the storage tank (40, 41), and the fluidic measuring section (60) of the analyte Sensor (20).n n n When the cartridge module (12) is inserted into the base module (14), the pumping mimic (36, 36 ') is driven by the pump drive (16, 16') and the fluidic measuring section (60) is connected to the analyte sensor (20). |
