Request More Information TOC-L Analyzer Configurator

Easily analyze all types of organic compounds with the global standard for TOC analyzers

Successfully measure TOC – even in hard-to-decompose samples or high-sensitivity applications

More than 40 years ago, Shimadzu developed the 680 °C combustion catalytic oxidation method for TOC analysis, setting the global standard for accuracy and reliability. The TOC-L series uses this technology to oxidize both easily decomposable and hard-to-decompose organic compounds.

Available as standalone or PC-controlled models, the high-sensitivity unit is ideal for pure water analysis, while the standard model focuses on cost-efficiency when high sensitivity measurement is not required.

Optional enhancements include simultaneous TOC and total nitrogen measurement, gas and solid sample analysis, and more. LabSolutions™ TOC software simplifies the entire analytical process.

High-temperature combustion catalytic oxidation method

  • No need for preparation and disposal of oxidizing agents

    The TOC-L analyzer is powered by Shimadzu’s 680 °C combustion catalytic oxidation method, which can effectively oxidize even challenging organic compounds like insoluble and macromolecular samples. This technology supports an extensive measurement range from 4 μg/L to 30,000 mg/L, suitable for analyzing everything from ultrapure to highly contaminated water.

    The automatic dilution function reduces sample salinity, acidity and alkalinity, significantly extending the lifespan of catalysts and combustion tubes.

Intuitive LabSolutions™ TOC PC Software supports the total analysis process

  • Perform imaging workflows quickly and easily with software-guided technology

    LabSolutions™ TOC software is easy to use and has many functions to simplify the analytical process. For example, the software can create a calibration curve out from one stock solution using the auto dilution function and automatically select the appropriate injection volume and dilution factor for samples that exceed the calibration range. Additional samples can be entered into the analysis sequence mid-run and measured ‘on the fly’.

    Users can also set automatic start-up and shut-down parameters for more efficient operation. And this software streamlines routine measurements, display real-time detector output, and provides customizable sample reports.
