Embodiment

[0022] A micro flow cell for detecting ECL signals of printed electrodes mainly includes a body 1 with a cavity 2 inside the body. Two sides of the cavity 2 are respectively provided with channels, and are connected to the outside through the channels. An opening 3 is provided on one side of the cavity where the channel is not provided, and a plug 4 is provided corresponding to the opening. The main body 1 is a flat rectangular box made of polymethyl methacrylate. The opening 3 is a printed electrode insertion port, and a rubber ring is arranged inside. The plug 4 placed corresponding to the opening 3 is made of rubber. After the electrode is inserted, it is buckled into the opening 3 and can be completely anastomosed, which can prevent liquid leakage. The channels opened on both sides of the cavity are the first channel 5 and the second channel 6, which are the inlet and outlet channels of the flow injection liquid respectively. The first channel 5 is connected to the flow ...

Abstract

The invention discloses a micro-flow cell for detecting an ECL (electrochemiluminescence) signal of a printing electrode and the application of the micro-flow cell. The micro-flow cell mainly comprises a body, wherein a cavity is formed in the body; channels are formed in two sides of the cavity respectively; the cavity is connected with the outside by virtue of the channels; an opening is formed in one side, not provided with the channels, of the cavity; a plug is arranged at the opening correspondingly. The micro-flow cell can serve as an ECL device or an electrochemical analysis device, is simple in structure, is small in size and is portable; the consumption of reagents is low, and an output signal is sensitive.

Description

Technical field [0001] The invention relates to the field of electroanalytical chemistry, in particular to a micro flow cell for detecting electrochemiluminescence (ECL) signals of printed electrodes and its application. The device is simple and sensitive, the constructed detection system has a small amount of copper ions in biological samples, and the analysis signal is sensitive. Background technique [0002] At present, the electrolytic cell suitable for ECL signal detection is mainly suitable for ordinary rod-shaped electrodes, with the opening at the upper end and the transparent bottom corresponding to the signal receiver. Insert the electrode vertically into the liquid surface, and the signal generated by the luminous body is directly received by the bottom detector. In addition, the test solution is fixed and cannot be circulated, which makes it inconvenient to add test samples. Because the screen printing equipment is simple and convenient to operate, printing and plat...
