The Model 1010 Total Organic Carbon [TOC], Analyzer is an automated system for analyzing aqueous samples for total inorganic carbon [TIC] and TOC. The Model 1010 performs both TIC and TOC analysis on one aliquot of sample. This allows TOC to be measured directly rather than through subtraction [TC-IC], as is the case with most TOC analyzers.

The Model 1010 uses approved 100℃ per sulfate oxidation  methodology for analyzing samples containing 2ppb to 10,000ppm of organic carbon. This heated per sulfate methodology has been proven to be the most reliable technique for acidic, ionic, refractory, and other difficult matrices. In addition, 100℃ per sulfate oxidation provides recoveries better than or equal to UV-promoted oxidation without the cost and maintenance of UV lamp replacement.

Total Organic Carbon Analyzer

Measures total carbon [TC], total inorganic carbon [TIC], and total organic carbon [TOC].

• Same-sample TIC/TOC measurement.
• Small, compact size.
• Ultralow-level sensitivity.
• Single-or multipoint calibration
• sequence programming for unattended operation.
• Programmable rinse capability.
• Nondispersive infrared [CO₂ specific] detector.
• For laboratory or at-line applications.
• Choice of interface options: keyboard and monitor, or Windows⁰⁰-based software [WinTOC^TM], for data han-dling and analyzer control.

Principle of Operation: Same-sample determination of TIC and TOC is performed by wet oxidation. TIC is determined by acidifying the sample to convert inorganics to carbon dioxide. The Carbon dioxide is purged from the sample and then detected by a nondispersive infrared detector [NDIR] calibrated to directly display the mass of carbon dioxide measured. This mass is proportional to the mass of TIC in the sample.

After TIC is removed from the sample, per sulfate reagent is added. The per sulfate reacts with organic carbon in the sample at 100℃ to form carbon dioxide, which is purged from the sample and detected by an NDIR. The resulting mass of carbon dioxide is proportional to the mass of TOC in the sample.
