TOC-L Series - Specs
Total Organic Carbon Analyzer
Improvements from the TOC-V Series（TOC-VCSH/CPH/CSN/CPN）
The TOC-L series provides even better functionality and operability than the popular TOC-V series. In addition, applications can be further enhanced by adopting new options such as a kit for small sample volumes and a high-salt sample combustion tube kit.

Improvements from the TOC-5000 Series
The TOC-L series adopts the 680°C Catalytic Combustion 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 catalytic combustion oxidation method. In addition, the catalytic combustion 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.
| TOC-5000(A) | TOC-LCSH/CPH | |
|---|---|---|
| Measurement range | 4μg/L to 4,000mg/L | 4 μg/L to 30,000 mg/L (significantly extended thanks to the automatic dilution function) |
| Automatic dilution | None | Yes, the dilution function can reduce the sample acidity, alkalinity, and salinity, extending the period of use of catalysts and combustion tube. |
| NPOC measurement time (No sampler) |
10.5 minutes, sample fractionated into vials -> acid added -> sample set -> conditions set -> measurement | 6.4 minutes (approx. 40 % reduction), sample set -> conditions set -> measurement |
| IC pretreatment | Sparging only, automated treatment outside the analyzer | Both the addition of acid and sparging performed automatically inside the analyzer |
| Rinsing water | None, replacement rinsing by sample (rinsing with sample ) only | Yes, capable of replacement rinsing by sample (rinsing with sample), and cleaning by rinsing water (also used as dilution water) |
| COD/BOD conversion | Function not available | Function not available |
| Total nitrogen measurement | Not available | Available with TNM-L (option); capable of simultaneous TOC and TN measurement |

| Number and type of data saved | Measurement results: 200 sample average values can be saved | All measurement results including peak data for 2,000 or more samples, as well as up to 60 calibration curves (TOC-LCSH) |
| Output of saved data | Not available | Capable of output to a USB memory stick (TOC-LCSH) |
| NDIR light intensity adjustment | Required | Not required (automatic adjustment) |
