PORTABLE SYSTEM FOR PHYSICOCHEMICAL ANALYSIS OF A SOIL FLUID

摘要

The present invention relates to a portable system (1) for sampling and physicochemical analysis of a fluid, comprising a fluidic circuit, wherein the fluidic circuit comprises: a sampling module (2) configured to collect a sample of a fluid extracted from a soil; a disposable and removable cartridge (3) comprising a first storing chamber (4) filled with a first calibration liquid and a second storing chamber (5) filled with a second calibration liquid and further comprising a first measure chamber (7) comprising at least one disposable physicochemical sensor (8); a distribution module (9) in fluid communication with the sampling module (2) and the disposable and removable cartridge (3), wherein said distribution module (9) is capable of fluidly connect the first measure chamber (7) to one of the storing chambers (4, 5) or to the sampling module (2); and a pumping means to provide a flow from the sampling module (2) to the first measure chamber (7) and a flow from one of the storing chambers (4, 5) to the first measure chamber (7).
