Dry type test paper light reflection detection device and detection method thereof

Abstract

The invention discloses a dry type test paper light reflection detection device. The device comprises a mainframe, a red light irradiation detection hole, a blank control hole, a blue light irradiation detection hole, a green light irradiation detection hole, an optical filter, and a rubber gasket; the red light irradiation detection hole takes a red light diode as an excitation light source, theblue light irradiation detection hole adopts a blue light diode as the excitation light source, and the green light irradiation detection hole adopts a green light diode as the excitation light source. Through three-primary color wavelength determination, the color change information can be determined more precisely by simulating a color identification algorithm, the detection accuracy is increased, and one blank control hole is increased, the influence of a sample matrix effect can be reduced, the detection sensitivity, the linear range and the repeatability are increased.

Description

technical field [0001] The invention relates to a light reflection detection device and method, in particular to a dry test paper light reflection detection device and a detection method thereof. Background technique [0002] The principle of the dry biochemical detector is based on the color of the biochemical reaction, through the light reflection detection technology to measure the light reflection value for quantitative analysis, and the light reflection detection usually needs to determine the measurement wavelength light source according to the color of the biochemical reaction (maximum absorption wavelength), and For a large number of biochemical detection items, the measurement wavelengths are different, and it is difficult to complete all items on a single detection platform. The biochemical reaction product is sometimes not only a single-color reaction, but also involves a change in color and a change in the maximum absorption wavelength of the reaction product. It...
