The current state of the art engineering for thermal catalytic oxydation uses temperatures between 680° and 1000°C. The QuickTOC^® has been engineered to work without the aid of expensive catalysts by using temperatures of more than 1200°C. Therefore, difficult to combust compounds are oxidized effectively and rapidly, regardless of their composition.

The QuickTOC^® is designed to operate in a batch mode. The TOC is analysed in 3 minutes. This guarantees the determination of fast and transient peaks throughout the day.

The sample is taken using the patented and maintenance-free sampling system FlowSampler. FlowSampler works filtration-free and takes the sample in the centre of the sample stream against the direction of the main flow.

Even solid particles are sampled by the FlowSampler and reduced in size by a homogenizer. The sample is then pumped by the homogenizer through a flow through sample cell. In the sample cell the sample is continously stirred to keep it in a homogenized, representative state.

The sample injection volume is controlled by a xy syringe sampling system. The sample aloquote is then injected into one of two injection ports of the two reactors.

By using a temperature of more than 1200°C the QuickTOC^® obtains complete combustion of the organic and inorganic components in the sample by using atmospheric air only.

That means greater reproducibility from the QuickTOC^® and no maintenance costs because there is no need to replace expensive catalysts.

At this high temperature all the inorganic carbon is converted to CO₂. This enables the true calculation of TOC from the difference between TC - TIC. It is important to note that the QuickTOC^® avoids the loss of the VOCs.

The measurement of the inorganic compounds is performed in an additional reaction vessel, in which a continous stream of acidified water is injected with the sample and the evolved CO₂ is stripped by the carrier gas.

The combustion gases from the two reactors flow through a 2 stage gas-cooler which is maintained at 4°C, to an absorption column before flowing into the IR detector.

The detection of CO₂ takes place in the NDIR analyser, which detects the CO₂ in form of a peak. The area of the peak is calculated by the built-in microprocessor.

The software supports every available function from controlling the QuickTOC^® to further processing of the measured values. An uncomplicated data transfer through serial or parallel interfaces to a monitoring station is a matter of course.

All these features result in an easy to operate analyser with low maintenance requirements, high reproducibility and fast measuring results for many years - the QuickTOC^® by LAR.
