The key point about a TOC analyzer is whether it can efficiently oxidize hard-to-decompose insoluble and macromolecular organic compounds, not just the easily decomposed, low molecular weight organic compounds. The 680°C combustion catalytic oxidation method, developed by Shimadzu and subsequently spread around the world, can efficiently analyze all organic compounds. The technique has been recognized for its ability to analyze samples with particulates, refractory compounds, and high salt matrices in wastewater and other difficult matrices. Again, this Shimadzu first has become the benchmark in the industry.

Features

Extremely wide range from 4µg/L to 25,000 mg/L for applications from ultrapure water to highly contaminated water.

• Combination of highly sensitive NDIR with a high-volume sample combustion system achieves sub-10 µg/L level TOC analysis.
• Specify the blank-check program to automatically conduct the blank check by creating and analyzing ultrapure water inside the system.
• High-concentration samples are analyzed by diluting to 25,000 mg/L with the built-in automatic dilution function.

Further evolution of the automatic sample injection system

Syringe with sparging function

• Efficient, automatic acidification and sparging for NPOC measurements reduces measurement time by approximately 40% (compared with other Shimadzu products).
• Automatic dilution reduces salinity, acidity, and alkalinity to considerably extend the maintenance period for the catalyst and combustion tube (maintenance period depends on the sample and measurement conditions).
• Dual flow-line washing methods: rinsing with sample or rinsing with dilution water.
• Sample intake tubes provided for individual TOC analyzer measurements during Autosampler use.
