TOC Analyzer HSC-TOCA – TC, IC and TOC, NDIR, up to 20,000 mg/L
Price on Request
TOC analyzer HSC-TOCA: measures TC, IC and TOC in water by high-temperature combustion (680 – 1,000 °C) or UV-persulfate oxidation with NDIR detection, up to 20,000 mg/L, detection limit ≤ 5 µg/L on high-sensitivity models, ±2%, automatic KHP calibration, USB / RS-232 / RS-485, LIMS. 1-year warranty.
The HSCo HSC-TOCA TOC analyzer measures total organic carbon in water and aqueous samples, for pharmaceutical, environmental, wastewater and industrial labs. It oxidises the sample by high-temperature catalytic combustion (680 – 1,000 °C) or UV-persulfate and measures the carbon dioxide with a non-dispersive infrared (NDIR) detector, giving total carbon, inorganic carbon and TOC. It reads up to 20,000 mg/L, down to 5 µg/L on high-sensitivity models, with ±2% accuracy, automatic KHP calibration and self-diagnosis. Results show on a digital or touchscreen display and go to USB, RS-232 / RS-485 or a LIMS.
Why labs choose it
- TC, IC and TOC in one instrument.
- Two oxidation methods: high-temperature combustion or UV-persulfate for low-TOC samples.
- NDIR detection: sensitive and fast.
- Wide range: up to 20,000 mg/L; detection limit 5 µg/L or lower on high-sensitivity models.
- Automatic: multi-point KHP calibration, auto-zero, self-diagnosis; autosampler optional.
- Connects to PCs and LIMS by USB and RS-232 / RS-485.

Questions buyers ask
How much organic carbon, and so organic contamination, is in the water.
UV-persulfate oxidation is offered for low-TOC samples; the other option is high-temperature combustion at 680 – 1,000 °C. Tell us your samples.
Yes, with the optional 8 – 60 position autosampler.
