UNIVERSAL DEVICE FOR FLOW ELECTROCHEMICAL ANALYSIS FOR SOLID-STATE AND PLANAR ELECTRODES AND METHOD OF MANUFACTURING SAME (EMBODIMENTS) Russian patent published in 2025 - IPC G01N27/28 G01R27/08 

FIELD: analytical chemistry.

SUBSTANCE: device for flow electrochemical analysis comprises an external housing, an open nut, a clamping bolt, a working electrode, a housing for the working electrode, a replaceable inner chamber for a working electrode, capillary tubes for inlet and outlet of liquid, a container for draining electrolyte, an electrolyte, a comparison electrode and an auxiliary electrode. Group of inventions in devices for flow electrochemical analysis can be made using 3D printing technology by layer-by-layer deposition using polymer plastics.

EFFECT: increase in the number of used varieties of electrodes due to the use of two versions of the replaceable inner chamber depending on the type of used electrodes – planar or solid-state, ensuring independence from third-party fastening materials for the device manufacturing due to use of 3D printed clamping bolt, simplification of the device manufacturing process due to fixation of all parts of the device by tightening of one hold-down bolt.
