  • Method of directly monitoring the concentrations of microbiocides in aqueous systems
    Patent number: 5514563
    Abstract: A method for directly measuring the concentration of biocides in aqueous systems comprising directly determining an absorbance or emission spectrum of the aqueous system in a wavelength range of from 200 to 2500 nm and applying chemometrics algorithms to the spectrum to determine the concentration of the biocides.
    Type: Grant
    Filed: March 3, 1993

    Assignee: W. R. Grace & Co.-Conn.
    Inventors: Jack C. Tully, Larry M. Kye
  • Spectrophotometric monitoring of multiple water treatment performance indicators using chemometrics
    Patent number: 5242602
    Abstract: The present invention is directed to a novel method for analyzing aqueous systems to simultaneously quantify the concentrations of multiple active or inactive treating components which may be contained therein. The method comprises determining the absorbance or emission spectrum of the components in the aqueous system over the wavelength range of from 200 to 2500 nm, and then applying chemometrics algorithms to extract and analyze features in the spectrum that are specific to the qualitative and quantitative concentrations from the specific components to simultaneously determine the concentrations of the components.
    Type: Grant
