Abstract

A process analysis unit includes a base module and an exchangeable cartridge module. The base module comprises at least one independent pump drive, and an analyte sensor without a fluidic measuring section. The cartridge module comprises a liquid reservoir tank, a sample taking device, at least one drive-less pump mechanism configured as a peristaltic membrane pump, a fluidic measuring section for the analyte sensor, and a plastic material plate with groove-like microfluidic channels configured to connect the liquid reservoir tank, the at least one drive-less pump mechanism, and a measuring section. The drive-less pump mechanism is driven pneumatically and pumps a liquid from the liquid reservoir tank. When the cartridge module is connected to the base module, the at least one drive-less pump mechanism is connected to and is driven by the at least one independent pump drive, and the fluidic measuring section is connected to the analyte sensor.
