CARBOSCAN 300 operates according the principle of optical absorption spectroscopy. This technology involves an electromagnetic beam hitting a sensor unit after having been split through a grid and directed through the gas being analyzed.

Two broadband spectrometer modules are used to selectively detect various contaminants. Since different substances cause different light attenuations in the gas, they can be uniquely identified using the spectrum, i.e. their physical fingerprint. Sum parameters can also be displayed.

CARBOSCAN 300 can currently selectively detect more than 40 different contaminants based on the light attenuation they cause. These include hydrocarbons of acetaldehyde, acetylene, from ethane and ethanol to methanol, propane and propylene, sulfur compounds, aromatic hydrocarbons and other components such as ammonia, NOX and water. If necessary, other components can be added at any time. The system satisfies the quality requirements of the ISBT (International Society of Beverage Technologists) and EIGA (European Industrial Gases Association).

Contaminants can be detected reliably down to sub ppb levels. The system can detect traces of benzene as low as 3 ppb. By way of illustration, this is the same degree of accuracy as if it were to reliably find and identify three people out of the entire population of China.

The system is calibrated at the factory, does not require calibration gas, fuel gas or zero air and does not need to be recalibrated by the operator. Automatic reference measurements, carried out at short intervals, safeguard measurement stability. As a result, there are no operating costs associated with the laborious task of bottle handling when exchanging calibration gas bottles as is usually the case with conventional systems. Operating and calibration errors by the operator are also excluded, eliminating downtime.

Operators of beverage bottling plants require CO₂ to carbonate their beverages. They need to ensure that the CO₂ they use is not contaminated with impurities that could affect the quality of the finished beverage. CARBOSCAN 300 offers reliable brand protection and therefore also safety for consumers.

Even breweries, which produce CO₂ as a waste product, can only use it in food and beverages if they can guarantee it does not contain any by-products from the brewing process, such as sulfur compounds, acetaldehyde and ethanol.

Gas suppliers can themselves only sell CO₂ if the client's specifications are met.

CARBOSCAN 300, with its sensitive and selective online process monitoring, safeguards continuous quality throughout the production process. Once installed, the turnkey system delivers reliable measuring results for years, providing suppliers and consumers with end-to-end quality and supply chain protection from costly quality incidents.
