Carbon dioxide (CO2) is a commonly used additive in food and beverage industry (e.g. for soft drink, brewery, and champagne carbonation). Its fabrication process can lead to the presence of impurities such as Benzene, Toluene, Ethylbenzene, Xylenes (BTEX) and sulfur compounds. To ensure people’s safety, limit values of these impurities has been set by various health and safety regulations.
Gas Chromatography (GC) is one of the most commonly used techniques for CO2 quality and purity monitoring to ensure meeting legal requirements. Chromatotec® has developed a GC analytical system for impurities measurement in CO2. It consists of a fully independent and automatic cabinet including the following modules :
The high stability and the ease of use make Chromatotec’s analyzers perfectly suitable for CO2 quality control. Moreover, results are validated by the internal calibration system.
