SKU331275


Total organic carbon (TOC) measurement is a well-established technique that provides valuable information about water quality for process control and regulatory compliance. 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 acid), these types of samples are problematic for combustion TOC analyzers.

  • Overview

    The 1080 TOC Analyzer processes aqueous samples for analysis of the total organic carbon (TOC), total inorganic carbon (TIC), 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 TOC employs a multi-step analysis technique to distinguish and quantify different forms of carbon present in sample matrices and determine TOC content. The value reported as TOC is the non-purgeable organic carbon (NPOC) content. NPOC is derived by first determining, or sparging, the TIC content of a sample and then introducing the TIC-free sample into the combustion reactor to oxidize organic compound constituents.

    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 (SSNDIR) 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 SSNDIR detector. The result is reported as the TOC content in both mass and concentration of carbon.

    The 1080 TOC Analyzer also supports other analytical approaches — including TC, TOC by subtraction (TC-TIC), and simultaneous determination of total bound nitrogen (TNb) using the optional TNb analysis module.

    Designed for Performance and Simplicity 

    High-temperature catalytic combustion oxidizes and converts the organic compounds present in aqueous samples to CO2 for measurement by a solid-state, non-dispersive infrared (SS-NDIR) detector. Patent-pending technologies protect the catalyst, increase reliability, reduce maintenance and operating costs, and extend the life of the instrument

    Automation

    The 1080 TOC also offers automatic sample acidification and sparging. The automatic dilution function reduces sample salinity, acidity, and alkalinity, significantly extending the dynamic range.

    Priority Sample on the Fly & Increased Throughput

    With intuitive software features, priority samples can be added at any time without interrupting the operation of the instrument. The Model 1088 Autosampler analyzes up to 88 samples unattended freeing the operator’s time for other projects.

    Compact Design 

    The autosampler was designed to fit beneath the 1080 TOC, conserving bench space.

    Intuitive Software and Optional Accessories

    TOCView provides fully automated data collection, analysis, reporting, storage in a LIMS environment using logical, and easy-to-follow design. Create methods for the analysis, set up and prioritize samples, quickly monitor instrument parameters, perform routine checks, review results, and generate reports all from TOCView. 

    The 1080 TOC can be equipped with a number of instrument options and automation accessories to improve sample throughput and productivity. Our 88-position Rotary Autosampler can be positioned below the TOC analyzer for convenient installation. Offering automated dilution, in-situ stirring, and 88 (40 mL) sample vials. The optional TNb Nitrogen detector allows the measurement of total bound (inorganic and organic) nitrogen (excluding N2) in aqueous samples in tandem with TOC analysis.
