Lower precision and higher vulnerability of optical CO2 measurement methods prohibit their primary use for analysis of carbon-dioxide packed beverages. The new OST (Steinfurth Optical Shelf Life Tester) combines the non-destructive functionality of the optical measurement with another precise measuring method delivering on this way a new interesting application for this technology.
The optical method is used for resource saving process monitoring and the high precise measurement (Steinfurth CDA) for system calibration and accurate measurement of the true carbon-dioxide content. With this setup the number of samples needed for CO2 shelf-life monitoring can be dramatically reduced and the most optimal process timing for accurate measurement estimated. With the exclusive combination of sample preparation and optical measurement (including the automatic measurement of the bottle neck diameter) in only one device Steinfurth OST is the most perfect solution for non-destructive and storage room saving shelf life analysis in packed beverages.
