Total Organic Carbon Analyzer for Water Samples

Total Organic Carbon Analyzer for Water Samples

Overview

The apparatus can determine the total organic content of environmental water quality, including tap water, surface water, river and lake water, seawater, domestic sewage, and industrial wastewater. It can also test organic content in new energy battery materials, chemical products and electroplating baths to support routine quality control. The UV oxidation mode works well for low-level organic water samples including drinking water, boiler feed water and purified water. For lab research needs, optional solid sampling, total nitrogen and total sulfur modules can be fitted, enabling organic, TN and TS measurement for both liquid and solid samples.

Features

1.      Equipped with an eight-way valve to automatically realize acid addition, sample injection and dilution.

2.      The‍‌‍‍‌ main unit offers the flexibility of persulfate oxidation or high-temperature catalytic oxidation for total carbons measurement. Such an approach gives you more standard methods ‍‌‍‍‌compliance.

3.      The‍‌‍‍‌ high-temperature catalytic furnace offers flexibility by allowing different catalysts to be adapted for different samples. It features a programmable temperature control system with the working temperature adjustable between 680 °C and 900 ‍‌‍‍‌°C.

4.      Heated and thermostatted inorganic-carbon reaction unit eliminates sample peak tailing, shortens assay duration and ensures repeatability of measurement results.

5.      Sample injection pump: syringe-driven injection delivers high precision and good repeatability; injection volume can be adjusted according to sample measurement sequences.

6.      High-efficiency Nafion tubing achieves effective water-vapor isolation without conventional dehydration membranes, better preventing gas-path blockage.

7.      Optional 24-position auto-sampler enables unattended operation to save labor and time.

8.      Optional solid-sample introduction module for measurement of solid and semi-solid samples.

9.      The inner wall of the detector gas chamber is electroplated with infrared high-reflectivity metal to reduce infrared-light loss and achieve high detection accuracy.

10.   Front-mounted combustion furnace for convenient operation and maintenance.

11.   Detector adopts 24-bit A/D conversion technology for more stable data, lower noise, wider detection range and faster response.

12.   Long-tube plug-grab halogen remover effectively mitigates halogen interference to the detector; manual halogen-removal-agent filling is not required.

13.   Expandable total-nitrogen detector for total-nitrogen measurement.

14.   Compliant with international standard ISO 8245.
