The contamination of the carbon dioxide can be a serious problem for the industry of carbonated beverages.
The contamination of the carbon dioxide can include residues transported from the power source, contaminants introduced in the substance in the liquid or present in the tanks of the distribution system.
The knowledge of the contamination of the CO2 sources and types of contaminants to reduce or eliminate is crucial in order to obtain a product of acceptable quality. Before being delivered, the pure CO2 from the outside air can be contaminated during transportation, storage and handling operations which take place several times before the gas arrives at the manufacturing plant.
The CO2 is produced from different techniques such as fermentation, combustion, ammonia/hydrogen production and others. It is required by the industry, especially for bottlers to control the supply chain by monitoring the CO2 purity allowing maintenance of the product quality.
Using the PlasmaDetek2(PED) plasma detector and the MultiDetek2 compact gas chromatograph, the analysis of the most critical trace impurities in carbon dioxide can be achieved in one unit with a single detection technology (PED).
By default, the configuration has 3 channels to cover the analysis of Benzene, Acetaldehyde, Nitrogen and Carbon Monoxide. If additional options for the analysis of Methanol, Sulfurs and Hydrocarbons are required, then channels 4, 5 and 6 are added in the same instrument.
