Embodiment 1

[0044] combined with Figure 6 and 7 As shown, the high-precision plunger type micro-sampling pump includes: guide rails, sliding brackets, plunger pumps, liquid inlet conduits, liquid outlet conduits, liquid outlet check valves, liquid inlet check valves, springs, cams and motor.

[0045] Described guide rail 9 is arranged horizontally, and links to each other with the bottom end of sliding support 10, so that sliding support realizes moving left and right on guide rail; A plunger pump 11 is arranged on the top of sliding support, and plunger pump is provided with liquid inlet and The liquid outlet (not marked in the figure), connect the liquid inlet conduit 19 and the liquid outlet conduit 18 respectively at the liquid inlet and the liquid outlet, and set the liquid inlet one-way valve on the liquid inlet conduit and the liquid outlet conduit respectively 17 and the liquid outlet one-way valve 12, preferably the liquid inlet and the liquid outlet are arranged vertically; o...

Embodiment 2

[0048] combined with Figure 8 and 9 As shown, the structure of the high-precision plunger micro-sampling pump is basically the same as that of Embodiment 1. A load cell is embedded in the clutch plate, and the load cell is preferably embedded in the center of the outer end surface of the clutch plate in contact with the cam. A sensor, the load cell is connected to a controller, and the controller is connected to a motor, wherein:

[0049] The load cell is used to collect the pressure signal generated by the contact between the cam and the clutch plate when the motor drives the cam to rotate, and transmit the collected pressure signal to the controller;

[0050] The controller is used to receive the pressure signal sent by the load cell, and compare this pressure signal with the set pressure signal, when the two pressure signals are equal or the pressure signal sent by the load cell reaches the set pressure When the signal is 90-95%, send a control signal to the motor to mak...

Abstract

The invention discloses an application method of a microorganism multi-parameter comprehensive test platform. A high-precision plunger type micro-scale sample feeding pump is used to precisely control the sample feeding of a microorganism test solution so as to stabilize the feeding quantity of the microorganism test solution during the whole test process and allow the microorganism test solution to enter from a liquid inlet, pass a micro-flow channel and discharge from a liquid outlet. A lens hole is connected with a microscopy hyper-spectrometer, and a background light source is turned on to provide background light for the microscopy hyper-spectrometer through a background light hole so as to collect microscopy hyper-spectrometer image information of microorganisms. Capacitive dielectric electrodes, planar waveguide and comb type electrodes and parallel electrodes are respectively connected with dielectric spectrum test equipment to detect the dielectric characteristics and number of microorganisms. An optical fiber through hole is connected with an optical fiber spectrometer to detect the spectral characteristics of the microorganisms. The microorganism multi-parameter comprehensive test platform is applicable to qualitative and quantitative detection of microorganisms in liquid, multi-information of the microorganisms can be synchronously collected, and detection efficiency and precision are increased.

Description

[0001] The application of the present invention is a divisional application of the parent application "multi-parameter comprehensive test platform for microorganisms". The application number of the parent application is 2015100275920, and the filing date of the parent application is January 20, 2015. technical field [0002] The invention belongs to the field of microorganism detection, in particular to a microorganism multi-parameter comprehensive test platform. Background technique [0003] Microbiological detection, especially the direct measurement of toxic microorganisms in food, has always been a research hotspot in food microbiological detection. At present, hyperspectral imaging technology has been widely used to study the quality, characteristics (pH value and viscosity) and pollutants (microorganisms and melamine) of food. In addition, hyperspectral imaging can be directly used to detect the viability of spores or endospores. A dielectric is a material that can un...
