Abstract: An apparatus for the non-destructive testing of the integrity and/or suitability of sealed packagings having at least one portion (111,121) at least partially optically transparent, preferably food packagings, in particular through a verification of conformity of the atmosphere inside such food packagings, wherein the apparatus comprises at least one inspection area (20); at least one laser source (11) with an optical axis (A); at least one detector (13) positioned so as to detect at least one portion of back-scattered beams (12?) following the collision of the laser beam (12) emitted by the laser source (11) with a target (100,200) and provide—at the output—a representative datum of an absorption spectrum of the gas. The apparatus includes means for measuring a distance covered by the laser beam (12) and electronic processing means for calculating the concentration of the gas.

Abstract: The present invention refers to a group for the in-line measuring of the quantity of carbon dioxide dissolved in a liquid contained in a closed container such as bottles, jars and so on and to an automatic containers filling plant comprising such measuring group. The measuring group according to the present invention comprises at least one inspection area (20,20?) suitable for housing at least one container (11), at the at least one inspection area (20,20?) being provided at least one laser spectroscopy device (16) for measuring the partial pressure of carbon dioxide present in the head space (13) of a container (11) placed in the at least one inspection area (20,20?), and it is characterised in that at the at least one inspection area (20,20?) there are additionally provided means for mixing (12) the content of said container (11).
