Title:
WATER QUALITY TESTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/242338
Kind Code:
A1
Abstract:
A water quality testing system, relating to the technical field of testing systems. The water quality testing system comprises a light source (2), a spectrometer (5), and a data processor (6). The light source (2) can be used for emitting excitation light pulse strings having different wavelengths to a water sample (1) to be tested contained in a sample cell (4). The excitation light pulse strings having different wavelengths can be emitted in a time division manner to excite said water sample (1), thereby generating fluorescence respectively corresponding to the excitation light pulse strings having different wavelengths. The spectrometer (5) is used for receiving the fluorescence, and outputting a fluorescence spectrum according to the fluorescence. The data processor (6) can be used for obtaining, according to the fluorescence spectrum outputted by the spectrometer (5), a three-dimensional fluorescence spectrum comprising an excitation light wavelength, a fluorescence wavelength, and fluorescence intensity, can identify said water sample (1) according to the three-dimensional fluorescence spectrum, and can obtain parameters of said water sample (1) according to the three-dimensional fluorescence spectrum. The universality of the water quality testing system is effectively improved.
