Electrochemical measurement cartridge

An electrochemical measurement cartridge comprising:

• a container comprising a plurality of compartments including a first compartment and a second compartment;
• a cover secured to said container to form, in said electrochemical measurement cartridge, an internal volume defining at least a first chamber within the first compartment configured to receive a first amount of a first fluid for analysis and a second chamber within the second compartment configured to receive a second amount of a second fluid;
• sealing means for hermetically insulating the first chamber from the second chamber;
• an electrochemical measurement sensor comprising at least one work electrode and one reference electrode and integral with said cover;
• said container and said cover being configured to move relative to one another in order to confer on the electrochemical measurement cartridge at least two distinct operating configurations, including a first configuration in which the electrochemical measurement sensor is placed in the first chamber to enter into contact with the first fluid present in said first chamber and to perform a first measurement on the first fluid, and a second configuration in which the electrochemical measurement sensor is placed in the second chamber to enter into contact with said second fluid present in said second chamber and to perform a second measurement on the second fluid, the first chamber is isolated hermetically from the second chamber such that the first amount of the first fluid remains in the first chamber within the first compartment and the second amount of the second fluid remains in the second chamber within the second compartment when the electrochemical measurement cartridge is in the first configuration and the second configuration and when the electrochemical measurement cartridge moves from the first configuration to the second configuration.
