More Information
Summary:Measuring device of the present invention includes a plurality of measuring sites for generating a plurality of optical path lengths and various dilutions. The range for concentration measurement and the measurement accuracy are enhanced due to the plurality of optical path lengths, and the interference on the measurement ranges and results caused by the concentration or the turbidity of suspended solid is reduced and removed by water sample dilution, and thus the characteristic wavelengths of the components in the water are measured. Next, the information of spectrum database is used to determine the ingredients which may exist in the water (qualitative analysis), and UV-VIS-NIR absorption spectrum analysis is used to obtain the concentration of the respective ingredients in the water at the same time (quantitative analysis).
