Instrument Technical Description and Major Specifications (This Specifications Limited to Major 5) ▪ Measurement Principle: High-temperature combustion (680°C) ▪ Detection Method: NDIR (Non-Dispersive Infrared) sensor ▪ Sample Volume: 0.1 – 2 mL (auto-injection) ▪ Analysis Time: 4-6 minutes per sample ▪ Calibration: Automatic multi-point calibration	Measurement/Sample specifications: ▪ Sample State: Liquid (aqueous solutions) ▪ Particle Size: Must be < 0.45 µm (filtered if necessary) ▪ pH Range: 2-11 (acidification may be required for NPOC) ▪ Maximum Salinity: 5% (w/v) (higher levels may require dilution)

● Quantity: 10-20 mL (volume depends on expected TOC/TN levels)

● Pre-Preparation:

o Must be filtered (0.45 µm) to remove suspended solids.

o Avoid samples with high volatility (use TC mode if necessary).

● Type of Samples Accepted:

o Drinking water, wastewater, industrial effluents, research samples.

● Label samples clearly with expected TOC/TN range.

● Indicate if TN measurement is required (if TN unit is installed).

● Maximum No. of Samples Accepted at a Time: 50 (autosampler capacity).

● Turnaround Time: 1-2 days (varies with sample load).

● Samples exceeding 5% salinity must be pre-diluted.

● No bacterial/fungal samples (instrument is for chemical analysis only).
