In some applications such as food and beverages or the energy sector, carbon dioxide (CO2) is used and must have a high purity in order to deliver its very best properties. For example, adding CO2 during the bottling process in the beverage industry is required at the highest purity in order to provide the right ‘fizz’ for a given beverage.
Depending on the processes, different kinds of impurities can be found in CO2, such as hydrocarbons, sulfur compounds, or other molecules. The challenge for those in the business of gas analysis and control is to find and detect these impurities, at extremely low levels, at any stage of the process in order to avoid the shutdown of an entire plant for clean up, or any other situation that an impurity may cause.
This includes being able to separate compounds and provide high sensitivity levels (LDL lower than 1 parts-per-billion/ppb).
