Theory of evolution for TOC continuous measurement
Combustion Oxidation - Wet Oxidation - UV Batch type oxidation
Conductivity detection - UV continuous type Oxidation Conductivity
The TOC contained in ultra pure water is decomposed
and oxidized by ultra-short waves (184.9 nm) to become an intermediate
and finally carbon dioxide and water. The TOC measuring technology of
the batch type has been the main stream traditionally, yet it has not
been unable to meet the needs in emergency because the batch type could
not detect a sudden increase of TOC or a change in water quality.
TAC series detect a variation of conductivity generated in the stage of
intermediate or carbon dioxide of complete oxidation by control and
application of the exposure dose of ultraviolet radiation, the sample
quantity of flow and the measurement algorithm, and by those calibration
curves the TOC measurement is conducted, enabling the process control
when a high speed mode in emergency and when an absolute mode when it it
hard to be influenced by a trace quantity of dissolved gases in sample
It is possible to measure the
variation of TOC and change of water quality in approximately 30 seconds
in the high-speed mode and 3 minutes in the absolute mode.
- Instant grasping of a change of water
quality in the continuous TOC measurement.
- Easy operation and maintenance-free.
- Compact designing.
- Utilizes a conductivity sensor for
precision measurement of a trace quantity of flow.
- Possible to decompose hard-degradable
TOC by a high-power ultra-violet lamp.
- Uniform oxidation characteristic
realized by a special chamber processing technology.
- Memory function of measurement
- Connectable to a printer.
- No needs for reagents and carrier
