Comparing optical and traditional measurement of dissolved carbon dioxide by in-line, at-line and laboratory instruments

The determination of dissolved CO2 is an important parameter in the quality control of carbonated beverages. While most analyses are based on pressure/temperature measurements, optical measurement technology in general is becoming more common in process environments, especially in the brewing and beverage industry, and offers many benefits, such as ease of installation, cleaning and compact size. Optical sensors also have no moving parts and are considered maintenance free.
