An electrochemical measurement cartridge includes a container including a first analysis chamber for receiving a fluid to be analyzed and a second calibration chamber for receiving a calibration fluid; an electrochemical measurement sensor including at least one work electrode and one reference electrode; a container supporting the sensor and a cover arranged mobile relative to one another to confer on the cartridge at least two separate operating configurations, a first configuration in which the sensor is communicating with the first analysis chamber and a second configuration in which the sensor is communicating with the second calibration chamber; sealing between the chambers of the container and the cover; and a drive member for providing a relative movement of the container relative to the cover.

Electrochemical measurement cartridge

A micropump with a deformable membrane, including: a first chamber, one wall of which includes a first deformable membrane portion and an actuator of the first membrane portion; a second chamber including a second deformable membrane portion and a third chamber, including a third deformable membrane portion, the second chamber and the third chamber being connected together through a first channel, at least one of the second and third chambers being connected through a second channel to the first chamber; each of the second chamber and third chamber including a mechanism forming a detection gauge, but not including an activation mechanism.

Micropump having a flowmeter, and method for producing same

A flowmeter includes a first chamber and a second chamber connected through a channel. The first chamber is provided with a first deformable membrane and with first and second gauges. The second chamber is provided with a second deformable membrane and with third and fourth gauges. The four gauges form a Wheatstone bridge.

Microflowmeter and method for making same

The device enables a second drop to be mixed in a first drop deposited on an electrically insulating layer of an analysis support, in a viscous liquid environment and to mix the resulting drop. The device comprises at least one injector forming the second drop above the first drop. After formation of the second drop, a voltage impulse is applied between a first electrode, arranged under the electrically insulating layer of the analysis support, underneath the first drop, and a second electrode arranged near the outlet orifice of the injector. The voltage impulse fosters the coalescence phenomenon between the two drops, while preventing risks of contamination of the injector by the reagent of the first drop.
