Abstract
A method is for expanding the solute-identifying capabilities of an infrared (IR) sparging system. In IR-sparging, bubbles transfer solutes contained in a volume of liquid to a gas stream which is analyzed in a gas cell. FTIR spectrometry provides spectral absorbance analysis to identify and measure the solutes. By repeating the spectral scans at given time intervals, data is also obtained which is related to the depletion rate curves of the respective solutes. Using this depletion rate data to complement the spectral analysis data provides major benefits in successfully identifying the solutes.
