The truth about CO2 in beverages
Portable and laboratory gas meters are commonly used to measure dissolved carbon dioxide in beverages. Many existing methods lack selectivity and provide values influenced by other gases like air, oxygen, and nitrogen, resulting in inaccurately high CO2 readings. To accurately determine true CO2 concentration, a selective and precise technology is required. This report presents the Multiple Volume Expansion (MVE) method, which effectively addresses this issue
Most selective and precise CO2 determination: No influence of other dissolved gases
When it comes to dissolved carbon dioxide (CO2) determination in beverages, it is essential that CO2 results are unaffected by other dissolved gases such as air or oxygen (O2) and nitrogen (N2). Many commercially available CO2 meters measure the sum of all dissolved gases that attribute to the result of carbon dioxide, thus obtaining results with higher values. Anton Paar dissolved CO2 meters avoid this error due to the Multiple Volume Expansion (MVE) method. Additionally, they require as little as 100 mL of sample.
