Abstract

The invention discloses a fluorescent whitening agent detector which comprises a detector body, and a display screen and a fluorescent detection module are arranged on the upper surface of the detector body, and the fluorescence detection module comprises a detection main body and a detection cell. The invention also discloses a detection method of the fluorescent whitening agent detector, which comprises the steps of putting to-be-detected samples into the detection cell, then arranging into the detection main body, detecting and reading. The fluorescent whitening agent in products is subjected to quantitative detection by means of the detector disclosed by the invention in a quick, accurate and easily portable manner on the spot; the detection method of the detector is simple, fast and accurate.

Description

technical field [0001] The invention relates to a detection instrument and a detection method thereof, in particular to a fluorescent whitening agent detection instrument and a detection method. Background technique [0002] Fluorescent whitening agent, commonly known as white dye, is a fluorescent dye and belongs to a complex organic compound. Its characteristic is that it can excite and absorb incident ultraviolet light to produce fluorescence, that is, after absorbing ultraviolet light (the wavelength range is about 360nm-380nm), it is excited to produce visible light with a wavelength in the range of 400nm-600nm, so it can compensate for the unwanted yellowish color in the matrix. As a result, the color of the item appears whiter, brighter and more vivid visually. Due to this characteristic, water-soluble fluorescent whitening agents are widely used in food, paper, paint, washing powder and cotton fabrics, while water-insoluble fluorescent whitening agents are used in c...
