The 1080 Total Organic Carbon Analyzer uses high-temperature (680 ºC) catalytic combustion to oxidize and convert organic compounds present in aqueous samples to CO2 for measurement by a solid-state, non-dispersive infrared detector (SS-NDIR). Though high-temperature combustion TOC has been shown to be very effective for the analysis of samples that are of high molecular weight or contain substantial amounts of salt or difficult-to oxidize organics (e.g., humic acids), these types of samples are problematic for typical combustion TOC analyzers. Our patented technologies protect the catalyst, increase reliability, reduce maintenance and operating costs, and extend the life of the instrument.

  • Overview

    Designed for Performance and Simplicity

    The 1080 processes aqueous samples for analysis of the total organic carbon total inorganic carbon and non-purgeable organic carbon (NPOC) content. Supporting USEPA-approved methods, Standard Methods, ASTM, DIN/ISO/CEN, and EU Methods our 1080 can analyze up to 300 samples per 24-hour period, depending upon the protocol employed, in excess of 100,000 samples per year. Principal applications include wastewater, seawater, industrial process water, drinking water, groundwater, and cooling water.

    The 1080 also employs a multi-step analysis technique to distinguish and quantify different forms of carbon present in sample matrices and determine organic content. 

    TIC concentration is determined by acidifying a sample to a pH less than 2. Carbonates and bicarbonates in the sample dissociate, forming CO2, which is measured by a solid-state non-dispersive infrared detector (SS-NDIR) and reported in mass and concentration values.

    TIC-free samples are Pulse-Timed injected into the reactor to perform high temperature (680 ºC) combustion over a platinum catalyst. Organic compounds are oxidized and converted into CO2, which is then quantified by the SS-NDIR detector. The result is reported as the TOC content in both mass and concentration of carbon.

    The 1080 Analyzer also supports many analytical approaches — TC/TIC/TOC/NPOC analysis techniques and standard measurements, as well as simultaneous determination of total bound nitrogen (TNb) using the optional TNb analysis module.
