Indoor detecting probe of fluorescent solution concentration

Abstract

The invention discloses an indoor detecting probe of fluorescent solution concentration. The probe comprises an exciting light source part and a fluorescent induction part which are oppositely arranged. The exciting light source part comprises a lower plate lens. A UV lamp is arranged below the lower plate lens. The fluorescent induction part comprises an upper plate lens. A narrow-bandpass filter is arranged above the upper plate lens. A photosensitive resistor is arranged above the narrow-bandpass filter. The lower plate lens and the upper plate lens are coaxially and oppositely arranged. Fluorescent signals of trace concentration can be captured, the fluorescent solution concentration can be conveniently and rapidly measured through the fluorescent characteristics of a fluorescent agent, and sensitivity is high. The indoor detecting probe is small in size, stable in structure, low in price, high in detection precision and particularly suitable for low-concentration fluorescent solutions, can rapidly detect fluorescent diluent concentration, and can adapt to detection of concentrations of various fluorescent agents.

Description

technical field [0001] The invention belongs to the field of experimental supplies, and relates to a device for measuring the concentration of fluorescent solutions, which is mainly used for indoor physical and chemical experiments and fluorescent agent detection in daily life. Background technique [0002] Fluorescent agents are widely used in scientific research, medical treatment, chemicals, engineering geological exploration and other fields. In daily life, fluorescent agents are widely used in the whitening of paper, coatings, detergents, cotton fabrics, etc. In the field of engineering, domestic and foreign scholars introduce fluorescent agents into groundwater systems as tracers to obtain important hydrogeological parameter. The study of fluorescent agents is of great significance, and it is necessary to conduct rapid qualitative and quantitative detection of them. [0003] The instruments for detecting fluorescent agents in the laboratory mainly include fluorescenc...

Problems solved by technology

The two instruments are expensive, and ordinary scientific research institutions are unable to purchase them, and high-quality instruments are largely dependent on imports in China, and their prices are getting higher and higher

In addition, you may come into contact with substances containing fluorescent agents everywhere in your daily life, such as underwear and paper towels. Usually, fluorescent detection lamps are used in households to detect the presence of fluorescent agents, but their concentration cannot be detected.
