Humic substances are dissolved organic matters contained in environmental water such as river and lake water. Humic substances, depending on their forms, have different fluorescence properties and thus, the fluorescence spectrum analysis is a useful analysis method for the identification of humic substances. 

This time, the humic substances contained in tap water were analyzed by a fluorophotometer. By analyzing the fluorescence spectrum, the decrease in the amount of the humic substances in the tap water treated with a home use water purifier was confirmed. 

By using the F-7000 fluorophotometer, the data is obtained at the ultra-high scan speed of 60000 nm/min and therefore, the fluorescence properties can be easily confirmed even when a large number of samples are to be analyzed. In addition, the instrument has the highest sensitivity for the instrument class and is suitable for the analysis of trace humic substances contained in samples such as tap water.
