1080 TOC Analyzer


Technology:TOC

OI Analytical

Supporting USEPA-approved methods, Standard Methods, ASTM, DIN/ISO/CEN, and EU Methods

Description

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 the 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 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.
