Abstract
The invention discloses a rapid assembly micro-flow detection cell device with magnetic separation. The device provided by the invention comprises a flow detection cell device and a magnetic separation rack. The flow detection cell device comprises a cover plate, a base plate, a sealing member, a detection chip, an interface board, magnets, pipeline connectors and pipelines. Two pipeline connectors are used to respectively install the pipelines at a fluid inlet and a fluid outlet of the cover plate. The bottom of the cover plate is provided with a seal groove used for installation of the sealing member. The sealing groove is positioned below the two pipeline connectors. The bottom of the cover plate is provided with an interface board slot used for fixing the interface board. The interface board and an electrical connection point of the detection chip are in elastic contact. The top surface of the base plate is equipped with a chip groove used for inserting the detection chip. The magnets are inserted in the bottom of the cover plate and are also inserted in the top surface of the base plate. The cover plate and the base plate are close to each other and sealed through the upper and lower magnets due to opposites attract. The device provided by the invention has advantages of rapid installation, simple structure, advanced function, cleaning convenience and the like, and can be widely applied in the fields of biology, chemistry, life science and the like.
Description
technical field [0001] The invention relates to the field of analysis and detection, in particular to a rapidly assembled microflow detection cell device with magnetic separation. Background technique [0002] The microfluidic detection device is the product of the development of micromachining technology and microelectronics technology. It has the advantages of high detection sensitivity and low consumption of samples, and is widely used in the fields of biology, chemistry, and life sciences. A microfluidic detection device usually includes a microdetection chip and a flow cell. How to organically combine the micro-detection chip with the flow cell is an important technical problem. At present, the commonly used method is to combine the microelectrode and the flow cell into a non-detachable whole through a certain method. This method requires high processing and makes the chip expensive. If the seal is not good, it will easily lead to leakage, or if the installation posit...
