Product Description Shimadzu´s state-of-the-art TOC analyzers maximize both sensitivity and productivity, making them the ideal choice for monitoring rivers, lakes, and oceans, assisting in the management of water from public sources, wastewater, and manufacturing processes, and, in the pharmaceutical industry, performing validation processes to meet the required regulations.

*** Includes ASI-L Autosampler (for 40ml samples), HP Compaq 6200 (with the the control software, TOC-Control L), and many consumables ***

The Shimadzu TOC-L Series of laboratory total organic carbon analyzers offers the optimum selection of performance features and options to meet the specific requirements of total organic carbon testing in a wide range of aqueous samples.
An ultra-wide measurement range and Shimadzu's patented 680°C Combustion Catalytic Oxidation/NDIR detection method make the TOC-L analyzers the ideal solutions for quality control, process control, and experimental research applications in the environmental, chemical, and pharmaceutical industries. The combustion catalytic oxidation method completely oxidizes easily decomposed, low-molecular-weight organic compounds, as well as hard-to-decompose insoluble and macromolecular organic compounds.
In addition, the temperature required for catalytic combustion is significantly lower than required for combustion without a catalyst, increasing combustion tube life and minimizing the effect of high salt content in samples.
This high-temperature catalytic oxidation technique is specified in several US EPA-approved methods, including:
EPA 415.3
SM 5310B
ASTM D7573
A sample range of 4 µg/L to 30,000 mg/L (with the automatic dilution function) enables measurements of everything from ultrapure water to highly contaminated water.
Features automatic sample acidification and sparging, as well as an automatic dilution function that reduces sample salinity, acidity and alkalinity. This significantly extends the use of catalysts and combustion tubes.

While providing an ultra wide range of 4 µg/L to 30,000 mg/L, these analyzers boast a detection limit of 4 µg/L through coordination with NDIR. This is the highest level of detection sensitivity available with the combustion catalytic oxidation method. In addition, the combustion catalytic oxidation method makes it possible to efficiently oxidize not only easily-decomposed, low-molecular-weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds.

- Capable of TC, IC, TOC (= TC-IC), and NPOC measurement; options enable POC (volatile organic carbon), TOC via POC + NPOC, and even TN (total nitrogen) measurements
- The blank check function evaluates system blanks by measuring ultrapure water processed automatically within the instrument
- The automatic dilution function enables measurements up to 30,000 mg/L
- Automatic sample acidification and sparging
- The automatic dilution function reduces sample salinity, acidity, and alkalinity, significantly extending the period of use of catalysts and combustion tubes (The period of use depends on the sample and measurement conditions.)
- Stat or priority samples can be added at any time to the analysis schedule without interrupting operation even when an autosampler is used
- Optional kits and modules are also available to accommodate samples with solids and sludge matrices.

When used in connection with a Solid Sample Combustion Unit (not included), water-insoluble residues that are difficult to extract in water can also be collected, and measurement can be quickly and easily conducted without the need for any pretreatment, such as sample extraction, etc.
