A fluorescent whitening agent field detecting instrument is characterized by comprising a fluorescent detection module, a liquid crystal display module and a detection system formed by a microprocessor, wherein the fluorescent detection module contains a fluorescent detection matrix, an optical fiber light source module, an optical fiber detector module and a fluorescent bearing plate; after the light emitted from the optical fiber light source module irradiates the fluorescent bearing plate, a substance to be detected generates the fluorescent light and the fluorescent light irradiates the optical fiber detector module, the information detected by the optical fiber detector module is transferred to the microprocessor, processed by the microprocessor and then collected to form a detection system database, and the detection result is displayed on the liquid crystal display module. The two-in-one optical fiber light source module is used, so the design is novel and the detection range is wide. The fluorescent bearing plate is used, so the detection is convenient. The detection system controlled by the microprocessor is used, so the practicability is strong.
Description
technical field [0001] The invention relates to an on-site rapid analysis instrument, in particular to an on-site rapid quantitative detection of fluorescent whitening agent content in solid and liquid products. Background technique [0002] Fluorescent whitening agent, commonly known as white dye, is a complex organic compound. Its characteristic is that it can excite and absorb the incident ultraviolet light to produce fluorescence, which visually makes the product brighter and brighter. Fluorescent whitening agents are generally divided into two categories, one is water-soluble whitening agents, which can be used as whitening agents for paper, paint, washing powder and cotton fabrics. The other is water-insoluble whitening agent, which can be used for whitening chemical fibers and plastics. [0003] When washing powder or cotton fabrics containing fluorescent whitening agents are in contact with the human body, the fluorescent whitening agents will migrate to the human ...
