Drinks equipment manufacturer Anton Paar is encouraging breweries to think again when it comes to CO2 measurement
According to the business, the solution comes in the form of the CarboQC and CBoxQC. These measure the true dissolved carbon dioxide content in beverages without the influence of other dissolved gases such as nitrogen.
The amount of CO2 gas in a beverage is a critical quality parameter in production. Many different test methods have been developed over the years including both chemical and physical test methods. Over time the physical methods of measurement have become the preferred methods for beverage testing.
In their basic form these rely on the measurement of the temperature and pressure of gas in the headspace of the can/bottle, and use the ideal gas laws to convert this into a CO2 content.
That is fine when the only gas present is CO2, but when other gases such as air, or nitrogen are present then these methods will give false readings.
The total pressure reading obtained is a sum of the partial pressures of each different dissolved gas, but these simple instruments treat the total pressure as if it all comes from CO2, leading to erroneously high results, and potentially to out of specification product.
Anton Paar said it has the answer to this problem. Uniquely amongst producers of dissolved gas test instrumentation, our instruments use a patented multi-volume expansion technique. This allows the CarboQC CBoxQC or CarboQC ME models to test the true CO2 content in a beverage container without any influence from other dissolved gases – including Nitrogen purge gas.
In addition to a true CO2 content, the CBoxQC will also measure the Oxygen content in the container. All three models will measure the gas content directly from the can or bottle when used in combination with our PFD piercing device or PBA beverage analysis systems.
During the rest of 2022 Anton Paar Ltd will offer a 15% trade-in discount for every old dissolved gas measuring unit replaced by a CarboQC or CBoxQC.
This exceptional offer could help ensure that soft drink production continues through the current CO2 shortage and that normal quality standards are maintained.
