Total Organic Carbon Analyzer (TOC)
Total Organic Carbon (TOC) Analyzer is engineered to provide precise and reliable measurement of organic carbon levels in water samples. This advanced system is ideal for monitoring water quality across various applications, including environmental testing, pharmaceutical production, and industrial processes.
By combining cutting-edge technology with dependable performance, Total Organic Carbon Analyzer provided by Drawell ensures accurate monitoring and control of organic contaminants, enhancing water quality and safeguarding processes.

Features of TOC
- Powerful operating software based on method management and sample management to help customers improve work efficiency. The instrument is truly intelligent and automated.
- It fully complies with GMP requirements for computerized system verification, and FDA 21 CFR PART 11 requirements for electronic data integrity, electronic signatures, and audit trails.
- Using the ultraviolet photocatalytic oxidation method, no catalyst or carrier gas is needed. The ultraviolet lamp cooperates with the self-developed and designed titanium dioxide catalytic coating spiral tube to make the ultraviolet wavelength more stable and the oxidation efficiency higher, especially suitable for the determination of organic carbon content in pharmaceutical water.
- An external online monitoring device can be selected to meet the needs of online monitoring.

Applications of TOC
TOC can be used to detect the concentration of total organic carbon in purified water, water for injection, and high-purity water in the pharmaceutical industry; it can be used to detect TOC in ultra-pure water such as semiconductor industry, power plants, scientific research institutes, pharmaceutical industry, and chemical industry. Such as:
- Drinking Water Treatment. Raw water (lakes, rivers, reservoirs) contains natural organic matter (NOM). During disinfection, NOM reacts with chlorine to form harmful disinfection by-products (DBPs). TOC monitoring ensures compliance with DBP regulations and verifies TOC removal efficiency.
- Pharmaceutical Industry. TOC monitoring ensures process water and products are free from organic impurities, and can indicate endotoxin presence.
- Chemical Industry: Online monitoring of TOC in process wastewater, which is complex and may contain substances that are difficult to oxidize.
How to Choose the TOC?
Working Principle of TOC Analyzer

- The water sample enters the device through the inlet. Then, it is divided into two equal flow paths.
- One passes through the delay coil 4 and enters the sensor 3, and the response value of the sample which is not oxidized may be tested.
- The other passes through the spiral quartz glass tube 1, and enters the sensor 3 after the organic substance in the water is decomposed into carbon dioxide under the irradiation of the UV lamp 2, and the response value of the sample which is oxidized may be tested.
- According to the difference between the response values before and after UV lamp oxidization, the TOC value may be obtained by using the corresponding formula.
- Finally, the liquid waste is discharged from the drain pipe through the peristaltic pump 5.
