TA-201E Total Organic Carbon Analyser

The TA-201E utilizes a high-temperature catalytic combustion oxidation technique to analyze carbon content in water samples. During measurement, the sample is introduced along with purified oxygen (as the carrier gas) into two separate pathways: a high-temperature combustion tube and a low-temperature reaction chamber. In the high-temperature combustion tube, organic and inorganic carbon compounds are oxidized into CO₂ via catalytic combustion. In the low-temperature reaction pathway, acidification of the sample breaks down inorganic carbon, converting it into CO₂. The carbon dioxide generated from both processes is then sequentially carried by the gas stream into a non-dispersive infrared (NDIR) detector for quantification. This allows for independent measurement of Total Carbon (TC) and Inorganic Carbon (IC), with Total Organic Carbon (TOC) calculated by subtracting IC from TC:
TOC = TC - IC

• Utilizes high-temperature catalytic oxidation to effectively break down even hard-to-oxidize organic compounds, making it ideal for analyzing high-concentration TOC samples.

• Delivers rapid results, with analysis times ranging from 1 to 4 minutes.

• Enhanced safety design: the combustion furnace is equipped with multiple layers of protection, including an independent overheating protection circuit that shuts off heating in case of abnormal temperature rise.

• Real-time flow monitoring system ensures stable gas flow and reliable measurement results.

• Full-system flushing and self-cleaning capabilities minimize contamination, reduce the risk of malfunction, and significantly lower maintenance requirements.

• Automated waste drainage, acid dosing, and acid discharge operations provide consistent reagent control and reduce operator intervention.

• Low reagent and sample consumption: each test uses only 0.5μL of ultrapure water, 2 mL of acid (for IC analysis), and approximately 2000 mL of high-purity oxygen (based on 100 mL/min flow rate and 20-minute ventilation under standard conditions).

• The non-dispersive infrared (NDIR) detector offers excellent linearity and sensitivity in CO₂ detection. The resulting CO₂ signal is converted into a peak curve, and TOC is calculated internally as the difference between TC and IC.

• The combustion process at 680°C ensures complete oxidation of nearly all organic substances while staying below the melting point of most salts, which helps extend the lifespan of the catalyst and combustion tube—especially beneficial for salt-containing samples.

• Features a high-resolution 7-inch touchscreen and intelligent operating system for user-friendly interaction and efficient workflow.
