Dosage of gaseous CO2

Carbon dioxide (CO2) is a naturally occurring gas in the air, used in numerous industrial, food, and environmental applications. Measuring gaseous CO2 allows for the measurement of its concentration in a gas, liquid, or atmosphere, whether for product quality control , validating a packaging process , or ensuring environmental compliance .

This analysis is essential for the food and beverage industries (carbonated waters, beers, wines, fermented drinks), modified atmosphere processing (MAP) , as well as in the control of industrial emissions or gas-permeable packaging materials .

Analytical methods: titration, electrochemistry, infrared (IR)

Depending on the matrix and the required precision, carbon dioxide can be measured using different methods:

• Acid-base titration : measurement of dissolved CO₂ after degassing of the sample, used for beverages or mineral waters.
• Electrochemical method : detection of CO₂ by specific sensor in gases or liquids.
• Infrared (IR) method : direct measurement of CO₂ levels by selective absorption in gaseous atmospheres.

These techniques offer high accuracy and comply with ISO and OIML standards applicable to carbon dioxide control in industrial products and environments.

Industrial and environmental applications

CO₂ measurement applies to various sectors:

• Food and beverage industry : control of carbonation in water, beer, wine or soda.
• Packaging and conditioning : verification of modified atmospheres (MAP) to extend the shelf life of food.
• Environment and air quality : measurement of CO₂ emissions in industrial facilities or confined areas.
• Materials and polymers : CO₂ permeability analysis for packaging films.
• Research and processes : monitoring of fermentation or decarbonation reactions.

This analysis can be complemented by the measurement of gaseous O₂ or gaseous N₂ for overall control of conditioning atmospheres .

Affected matrices

Our partner laboratories perform carbon dioxide analysis on different types of samples:

• Industrial gases and modified atmospheres
• Sparkling waters, beers, wines and fermented drinks
• Packaging and materials permeable to gas
• Ambient air, industrial gaseous emissions or effluents
• Laboratory samples obtained through chemical or biological processes

Each protocol is adapted to the matrix , the expected concentration level and the quality control or regulatory objectives .
