The Hydraspin Lab-TOC unit is an instrument designed for the measurement of the dissolved and finely suspended organic carbon contents of water. The analysis is based on photo oxidation of organic carbon.

That is a process of ultra-violet/peroxodisulphate oxidation of the organics in the sample followed by infrared detection of the carbon dioxide liberated.

Reagents:
Phosphoric acid solution. 05% v/v.
Potassium peroxodisulphate solution 4,0% v/v.
Reagent consumption depends on the analysis range selected but normally the acid will be consumed at a rate of 15 ml/min and the peroxodisulphate at 1 ml/min.

Temperature:
Sample 50‘C maximum, instrument 40'C maximum ambient.
Power Supply: 220V 50Hz 2A.

Principle of Operation

Sample from sampling well to glass flow manifold.
Sample is mixed with Ortophosphoric acid, which reacts and removes inorganic carbon compounds.
Inorganic carbon free sample is then mixed with potassium peroxodisulphate, which aids the oxidation of organic carbon to CO2 using ultraviolent activation.
The air/ CO2 mixture is dried and flows through the IR detector to detect C02 concentration.
A digital or 4-20 mA output signal, proportional to the CO2 concentration is fed via the Control Circuitry to the computer or server.
