Abstract

A multi-parameter rapid detection device and detection method for water bodies of the present invention, the device includes a microfluidic chip module, and the microfluidic chip module includes a dielectrophoretic bacteria sorting chip module, an impedance bacteria testing chip module, and an extraction fluorescence testing chip module , Electrophoresis ion chip module; four inlets are set on the microfluidic chip module, inlet one is used as sample inlet, inlet two, inlet three and inlet four are respectively used as buffer inlet one, buffer inlet two and buffer inlet three; the present invention The device adopts microfluidic technology, realizes precise flow control of liquid through microchannels and microvalves, and highly integrates multiple pretreatment and detection modules on a small plastic sheet, which has a high degree of integration and efficient mass transfer and detection speed. The whole device has strong portability, high detection speed and timeliness. Integrate multiple modules on the same chip to achieve joint detection of multiple parameters, and only need to input one sample, making the detection accuracy higher.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a multi-parameter rapid detection device and detection method for water bodies. Background technique [0002] my country's rivers, lakes, seas and other water areas are vast, and the quality of water bodies has an important impact on people's production and life. Water quality testing is the first step in measuring water bodies. At present, there are two types of methods for the determination of traditional water quality. One method is to collect water samples on site and bring them back to the analysis and testing laboratory for laboratory analysis in a short period of time. Traditional laboratory chemistry such as atomic absorption method and ultraviolet colorimetry are mainly used. Although the determination method has high precision, the process is cumbersome and requires a lot of manpower, material resources and financial resources. Another method is to est...
