TOC analysis

The TOC-L series products of TOC analyzer adopt 680 ℃ combustion catalytic oxidation method. This method was developed by Shimadzu and is now widely used worldwide. The measurement range of the analyzer is 4 μ g/L~30000 μ g/L. Can achieve a detection limit of 4 μ g/L. This is the high detection sensitivity that can be achieved using combustion catalytic oxidation method. In addition, the combustion catalytic oxidation method enables it to effectively oxidize not only easily decomposable low molecular weight organic compounds, but also insoluble and high molecular weight organic compounds that are difficult to decompose.

Wide measurement range of 4 μ g/L~30000mg/L, suitable for all substances from ultra pure water to highly polluted water (TOC-LCSH/CPH).
Can be used for TC, IC, TOC (=TC - IC) and NPOC measurements; The options can measure POC (volatile organic carbon), TOC (through POC+NPOC), and TN (total nitrogen).
The blank check function evaluates the system's blank by measuring the ultrapure water automatically processed within the instrument.
The automatic dilution function enables measurements up to 30000mg/L.
Reliable injection system
• Automatically perform sample acidification and blowing
The automatic sample dilution function can reduce the concentration of acid, alkali, and salt in the sample, which is of great significance for extending the life of catalysts and combustion tubes (the life of catalysts and combustion tubes depends on the sample and measurement conditions)
The sample can be inserted into the analysis table at any time, even when using an automatic sampler, without stopping the operation.

Four models for users to choose according to their needs

Single machine models and PC control models for configuring panels and LCD displays
A high-sensitivity model with a detection limit of 4 μ g/L, suitable for the determination of various samples including pure water.

In addition, using the external interface of USB enhances the device's versatility. Even standalone models can output to personal computer printers or USB storage devices.

Optional accessories to further enhance functionality

For the TOC-L series, various options and attachments can provide various enhanced functions. Including simultaneous measurement of TOC and TN (total nitrogen) (with the addition of TN module), use of air compressor (with the addition of carrier air purification component), measurement of gas samples and solid samples (with the addition of gas injection component and solid sample determination component).
The determination of seawater samples and trace samples has also been strengthened.

Space saving design and energy-saving design

The instrument width has been reduced by 20% compared to traditional Shimadzu models, making this design more efficient in utilizing laboratory space. Even with the addition of TN accessories, the width of the instrument remains unchanged.

This instrument is printed with the Shimadzu energy-saving logo. Compared with traditional Shimadzu models, it saves 43% (220V) and 36% (110V) energy
