TOC device

TOC device or TOC d analyzer is a laboratory equipment that uses the 680 ° C catalytic oxidation method, which has been developed and is now used worldwide. While offering an extremely wide range from 4 micrograms per liter to 30,000 milligrams per liter, these analyzes, in coordination with NDIR, have a detection range of 4 micrograms per liter. 

This is the highest level of detection sensitivity available by the catalytic oxidation method of combustion. In addition, the catalytic oxidation method of combustion makes it difficult for not only low molecular weight organic compounds to decompose easily, but also insoluble and macromolecular organic compounds to be difficult to decompose.

TOC device measurement range

Very wide measurement range from 4 micrograms per liter to 30,000 mg per liter, usable for everything from ultra-pure water to highly contaminated water (TOC-L  _{CSH / CPH}  )

• Capable of measuring TC, IC, TOC (= TC-IC) and NPOC. Measurement options for POC (volatile organic carbon), TOC via POC + NPOC and even TN (total nitrogen)
• Empty check function evaluates system voids by measuring ultra-pure water that is automatically processed in the machine
• The automatic diluent function makes it possible to measure up to 30,000 mg / l

Reliable sample injection system of TOC device

• Prototyping and automatic spring sampling
• The automatic dilution function reduces the salinity, acidity and alkalinity of the sample and significantly increases the period of use of catalysts and combustion tubes (duration of use depends on the sample and measurement conditions).
• Statistical or priority samples can be added to the analysis program at any time without interrupting operations, even when an automated sampler is used.

 4 models fit the  TOC device

The TOC-L series includes a high-sensitivity model with a detection limit of 4 micrograms per liter, which makes it suitable for a variety of applications, including pure water measurements and a standard model with cost performance. Each analyzer is available as a standalone model with LCD and keyboard or as a PC-controlled model.

In addition, the USB format is used as an external interface and increases the variety of equipment. Even standalone models can output to a public PC printer or a USB memory card.

Options to further increase the performance of the  TOC device

With the TOC-L Series, multiple options for a variety of performance enhancements are possible. These include the simultaneous measurement of TOC and TN (total nitrogen) (when a unit of TN is added), the use of compressor air (when a carrier gas purification kit is added), and the measurement of gas samples and solid samples ( When the gas is injected, a sample injection kit and a solid sample combustion unit are added. Seawater sample measurements and small sample volume options have also been increased.
