Abstract
In one aspect the current invention provides a method for automatic real time monitoring of true color in a liquid. A sample is automatically withdrawn from the liquid in real time and is then automatically filtered in real time. The true color in the filtered sample is automatically detected in real time and the true color is automatically quantified in the filtered sample in real time. In another aspect, the present invention provides an apparatus that automatically monitors true color in a liquid in real time. The apparatus has a pump for automatically withdrawing a sample from the liquid in real time and a filter for automatically filtering the sample in real time. The apparatus also has an absorption spectrophotometer for automatically detecting true color in the filtered sample in real time and a controller for automatically quantifying the true color of the filtered sample in real time.
