TOC Analyzer- HSC – TOCA

HSC- TOC Analyzer – Technical Specification

1. Measurement Principle:

   • Based on high-temperature catalytic combustion oxidation or UV-persulfate oxidation method.

   • Measures Total Carbon (TC), Inorganic Carbon (IC), and Total Organic Carbon (TOC) precisely.

2. Measuring Range:

   • TOC: 0–20,000 mg/L (expandable as per model).

   • Detection Limit: ≤ 5 µg/L (for high-sensitivity models).

3. Accuracy & Precision:

   • Accuracy: ±2% or better.

   • Repeatability: ±1% of full scale.

4. Sample Type:

   • Suitable for aqueous samples (drinking water, wastewater, process water, and effluents).

   • Optional module for solid or gas samples.

5. Injection System:

   • Automatic or manual sample injection.

   • Equipped with autosampler (optional 8–60 positions).

6. Detection System:

   • Non-Dispersive Infrared (NDIR) detector for CO₂ measurement after oxidation.

   • High-sensitivity detection with fast response time.

7. Oxidation Method:

   • High-Temperature Combustion: Up to 680–1,000°C with platinum or ceramic catalyst.

   • UV/Persulfate Oxidation: For low TOC samples.

8. Calibration:

   • Automatic multi-point calibration using potassium hydrogen phthalate (KHP) standards.

   • Self-diagnostic and auto-zeroing features.

9. Data Display & Interface:

   • Digital or touchscreen display showing TOC, TC, and IC values.

   • USB and RS-232/RS-485 interfaces for data logging and PC connectivity.

   • Compatible with laboratory information management systems (LIMS).

10. Sample Volume:

    • 10 µL to 5 mL (depending on model and concentration).

11. Carrier Gas:

    • High purity oxygen or air (99.995%), adjustable flow rate 150–200 mL/min.

12. Power Supply:

    • 220V ±10%, 50/60 Hz, single phase.

13. Dimensions & Weight:

    • Compact benchtop design, typically 400 × 450 × 450 mm, weight 15–25 kg.

14. Environmental Conditions:

    • Operating temperature: 10°C – 35°C

    • Relative humidity: ≤ 85% non-condensing

15. Compliance:

    • Meets ASTM D2579, EPA 415.1, ISO 8245, and EN 1484 standards for TOC analysis.

16. Optional Accessories:

    • Autosampler unit, external printer, solid sample module, and reagent bottles.
