TOC Analyzers

Total Organic Carbon Analyzer
TOC-L

The role of the TOC analyzer is to quickly and reliably measure all sorts
of organic compounds in water. The most important feature of such an
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.
Shimadzu TOC analyzers delivers both high-efficiency detection of
organic compounds via the 680°C combustion catalytic oxidation
method, and high sensitivity capable of even pure water management.

Brochure No. C391-E079

Extremely wide measurement range, from 4 µL 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 measurements. In addition, installation of optional units enables
POC (volatile organic carbon), TOC via POC and 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 effectiveness will differ depending on the samples and measurement conditions.)
Even when an autosampler is used, stat or priority samples can be added at any time to the analysis schedule without
interrupting operation by equipping the system with a sample collection tube for single-unit TOC analyzer measurements. Multifunction sample pretreatment injector
