Shimadzu Việt Nam - Trung Son T.S.S.E Scientific Equipment & Tourist Joint Stock Company

Joint Stock Company

Shimadzu Vietnam - Trung Son T.S.S.E Scientific Equipment & Tourist Joint Stock Company is an Exclusive Distributor of SHIMADZU, a famous brand of analytical instruments, since 2000 in Viet Nam

The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was developed by Shimadzu and is now used worldwide.  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.




 

Extremely wide measurement range from 4 μg/L to 30,000 mg/L, applicable to everything from ultrapure water to highly contaminated water (TOC-LCSH/CPH)

  • 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

Reliable sample injection system

  • 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 anytime to the analysis schedule without interrupting operation even when an autosampler is used

Select from 4 models to suit your application

The TOC-L series consists of a high-sensitivity model with a detection limit of 4 μg/L, making it suitable for a variety of applications, including pure water measurements, and a standard model designed with cost performance in mind. Each analyzer is available as an LCD and keyboard-equipped standalone model, or as a PC-controlled model.

In addition, the USB format has been adopted as the external interface, enhancing the equipment’s versatility. Even the standalone models are capable of output to a general-purpose PC printer or to a USB memory stick.
 

Options to further enhance functionality

With the TOC-L series, numerous options enable a variety of functional enhancements. These include simultaneous measurement of TOC and TN (total nitrogen) (when a TN unit 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 a gas sample injection kit and solid sample combustion unit are added). 
Sea water sample measurement and small sample volume options have also been enhanced.
 

Space-saving and energy-saving design

The width of the instrument is 20 % less in comparison with conventional Shimadzu models. This enables more effective use of laboratory space. The instrument width is unchanged even when the TN unit is added.
This product conforms with Shimadzu’s ECO labeled product. Energy Saving: Power consumption reduced by 36 % (100 V) and 43 % (200 V) as compared to a conventional Shimadzu product. (Assuming 8 hours operation/day × 5 days/week)

With the TOC-L series, accessories are also provided to enhance functionality.

High-salt sample combustion tube kit

When measuring samples containing salts, this kit extends the lifetime of combustion tubes and catalysts, reducing maintenance. It enables seawater measurements approx. 2,500 times by injecting 40 μL. (It’s not a guaranteed value.)

B-type halogen scrubber

This kit effectively removes corrosive gases produced when measuring samples containing salts, thereby decreasing NDIR cell degradation.

Kit for small sample volumes

This kit enables the measurement of smaller volumes of samples. Example of sample consumption: Standard specifications: 8 mL/3 measurements -> Using this kit: 5 mL/3 measurements. However, there are some performance limits, such as the maximum sensitivity range decreases to about 0 to 1 mg/L, maximum measuring range decreases to 2,000 mg/L, and the ASI-L and external sparging kit are needed to measure NPOC automatically.

Carrier gas purification kit

This kit removes carbon dioxide and other carbon-containing impurities by supplying instrumentation air, compressor air, and other pressurized air, so that they can be used as carrier gas. (Compatible with TOC-LCSN/CPN)

Gas sample injection kit

This kit enables manual injection of samples using a micro syringe.  Aqueous samples and gas samples can be injected. TC, carbon dioxide, and TOC (= TC - carbon dioxide) (Carbon monoxide is included in TOC) measurements in gas samples can be performed.

POC measurement kit

This kit enables measurement of the volatile organic carbon (POC) driven from the sample during the sparging process at room temperature.

Nitrogen carrier gas kit

High-purity nitrogen gas (max. 1 ppm of each CO, CO2 and HC) can be used as the carrier gas. Using this kit makes it possible to supply carrier gas directly from a nitrogen gas supply line. (Cannot be combined with the TNM-L) ※When this option is used, the measurement range for both TC and IC expands from the conventional range (0 to 500 μg/L) to 0 to 100 mg/L.

Suspended sample kit

The TOC-L series sample flow line is normally 0.5 mm. However, by introducing the suspended sample kit, this can be extended to 0.8 mm. This enables the measurement of samples containing large particles.
