Abstract

Disclosed is an apparatus for measuring the indicators of a specific ingredient in a solution. According to one embodiment of the present invention, said apparatus comprises: a signal collector for collecting a plurality of signals from a target in a selected volume of the solution. Beam splitters for splitting said signals and several designs for generating and transmitting the signals to the detectors. After the signal'"'"'s detection, a mold-in algorithm is used to remove the noise. The filtered signals are used to get several indicators, which are correlated to the concentration of ingredients in the solution. This apparatus is designed to enhance the power of the mold-in algorithm. The present invention provides an apparatus for effectively measuring in-situ without the need of extracting the solution out of its original container.
