OI Analytical 1080 TOC Analyzer

Saturday, 01 August, 2020 | Supplied by: Walker Scientific Pty Ltd

The 1080 TOC Analyzer from OI Analytical 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, the product can analyse up to 300 samples per 24 h period.

The device employs a multistep 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 oxidise organic compound constituents.

TIC-free samples are pulse-timed injected into the reactor to perform high-temperature (680°C) combustion over a platinum catalyst. Organic compounds are oxidised 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.

Other features include: a wide operational range (50 ppb–2000 ppm C); a patented Smart Slide injector that extends O-ring life and reduces maintenance; and patented Tube Guard that extends furnace tube life and reduces maintenance.
