  • Wide-range TOC instrument using plasma oxidation
    Patent number: 6793889
    Abstract: Total organic carbon in an aqueous or gaseous sample is measured by admitting the sample and an oxidant gas to a cell transparent to plasma, establishing a relatively low energy plasma in the cell, and measuring the CO2 thus produced using FTIR, NDIR, or conductivity-based techniques.
    Type: Grant
    Filed: August 14, 2001
    Date of Patent: September 21, 2004
    Assignee: Hach Company
    Inventors: Ulf W. Naatz, Yasuo Yamamori, John Stillian, Tsutomo Asano
  • Instruments for measuring the total organic carbon content of water
    Publication number: 20030040122
    Abstract: An improved instrument for measuring the total organic carbon content of water provides substantially instantaneous TOC measurements that are repetitively calibrated, provides substantially improved accuracy of results in a circuit providing improved noise rejection, allowing faster response, and provides controlled dilution of the sample stream to extent the useful range of the instrument.
    Type: Application
    Filed: July 2, 2002
