Shimadzu TOC-L Series


TOC-L Series

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

TC Running High

While using the instrument the TC started running high. We regenerated the catalyst, ran the line flush,as well as zero point. We checked the reference solution on another instrument and it checked out. What else do I need to look at? Thank You...

Shimadzu TOC-L Series Area Counts

I have two L Series insturments. One has the acid kit on it and one does not!  I run NPOC on the one with out the acid kit and the one with the acid kit I run TOC.  The one I run TOC on is down so I am trying to set up TOC on the other...
