Abstract
A method of analyzing the concentration of components in a fluid solution that can be contaminated with gas bubbles includes applying a spectrum of light to a test cell holding a sample fluid solution and detecting the measurement of the intensity of light passing through the test cell. A gas of the type that would be found in the sample fluid solution can be initially inserted into the test cell with light of a predetermined range of wavelengths scanning the test cell to obtain a reference spectrum. The test cell is then filled with the sample fluid solution and the light measurement is again conducted to obtain a sample spectrum. Data processing can occur to derive a light absorbance spectrum from the reference spectrum and sample spectrum to enable a determination of the percentage of concentrations of each component from the light absorbance spectrum, including the percentage of gas. Adding the determined percentages of concentration will provide a total amount, and comparing this total amount with a predetermined value can verify the accuracy of the concentration of components. If the data is contaminated as a result of an excess presence of gas bubbles, this data can be discarded to insure that the proper amount of concentrations is determined.
