Abstract

The invention discloses a portable fluorescence detection device. The fluorescence detection device comprises a detection container, an exciting light irradiation unit and a fluorescence detection unit, wherein the exciting light irradiation unit comprises a light source, a light source driving circuit and a first optical filter which is arranged on one side of the detection container and is opposite to the light source; the fluorescence detection unit comprises a second optical filter arranged on the other side of the detection container, a photoresistor arranged opposite to the second optical filter and a signal detection device connected with the photoresistor, and the included angle between the first optical filter and the second optical filter is 90 degrees. The invention further provides a portable fluorescence detection device which is simple in structure, low in price and convenient to use. Based on the portable fluorescence detection device, the invention further provides application of the portable fluorescence detection device in chromium ion concentration detection.

Description

technical field [0001] The invention relates to the technical field of detection, and specifically designs a fluorescence detection device and its application. Background technique [0002] Fluorescence detection is a commonly used detection technology. The "excitation light" is emitted by the light source, which is transmitted through an optical fiber or directly irradiated to the sample cuvette container. When the spectrometer is detected, the spectrometer reads out the corresponding data to complete the detection. Fluorescence detection has the advantages of convenient and fast use, high sensitivity and selectivity, and is widely used in sample detection in the fields of biology, food, and chemistry. [0003] Among them, the spectrometer used to detect the fluorescence emitted by the sample is a device for measuring the intensity of different wavelength positions of the spectral line with photodetectors such as photomultiplier tubes. Generally, it consists of an incident...
