Total Organic Carbon (TOC) Automatic AnalyzerNEW
Can be used with all types of samples, from source samples to discharge monitoring samples
Toray’s TOC automatic analyzers rapidly and accurately perform automatic analysis of total organic carbon content in rivers, lakes and marshes, sea areas and plant discharge, both online and offline.
These TOC meters use Toray’s unique low temperature sealed combustion technology, enabling them to provide stable measurement for long periods of time. They are economically priced, based on our over four decades of technology and usage track record, easy to operate, and compact.
This series of devices supports a wide range of samples and measurement points, from high concentrations such as source points to low concentrations such as discharge water and rainwater, providing long-term, stable measurement.
- 650°C sealed combustion, the industry’s lowest temperature, reduces the frequency with which catalyst maintenance is required
- Unique catalyst design and pre-processing filter ensure stable measurement of samples containing high concentrations of suspended matter and seawater samples
- New sample line cleaning function which uses acidic solution and minimum sample tube internal diameter of 2 mm helps prevent contaminants from impacting results and reduces adherence of suspended matter
- Lineup of four models to suit individual uses

Automatic cleaning filter
Our automatic cleaning filters, developed in-house, are sample filtration preprocessing devices which consist of net-less elements made up of stacked circular disks and cleaning blades.
The ACF element component uses a roughly 100 gauge net (equivalent to 147 μm) to catch matter suspended in samples.
The suspended matter is scraped off by the cleaning blades, washed off by the flow of excess sample, and evacuated via the drain.
Options such as a reverse cleaning function using cleaning water and functions for controlling element pass-through time are also available to reduce the amount of element clogging.
TDS Co., Ltd. provides maintenance, inspection, and consumable parts sales services.
