  • Testing method for residual organic compounds in a liquid sample
    Patent number: 11307138
    Abstract: A method and system for testing a liquid sample for an organic compound is disclosed, the method including the steps of collecting the liquid sample from a liquid source; transmitting light having a wavelength of between about 190 nanometers and about 310 nanometers into the liquid sample; measuring absorption/transmission of the light by the organic compound in the liquid sample; and determining a concentration of the organic compound within the liquid sample based on the absorption/transmission of the light by the organic compound. The system can include a spectrophotometer for measuring the absorption of UV light by the organic compound, an ion exchange column for removing ion contaminants from the liquid sample, and a vacuum degasser unit for removing gases and other impurities from the liquid sample.
