Features
The most important feature of a TOC analyzer is its ability to efficiently oxidize not only easily decomposed, low molecular weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds. The 680 °C combustion catalytic oxidation method, developed by Shimadzu and now used worldwide, can efficiently analyze all 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
- LCD and keyboard-equipped standalone models, and PC-controlled models
- High-sensitivity model with a detection limit of 4 μg/L, suitable for a variety of applications including pure water measurements, as well as a standard model designed with cost/performance in mind
- Suitable for aqueous samples, as well as gas and solid samples (with manual injection kit and solid sample combustion unit)
Compressed air can be used as the carrier gas (with carrier gas purification kit)
Compatible with small sample volumes (with optional kit)
Sea water samples can be continuously measured with minimal maintenance (with combustion tubes for high salt samples)
Measurement can be performed with good repeatability even with samples containing
highly sedimentary suspended organic matters (when high suspension kit is added)
※The effect depends on sample and measurement conditions
