| titleOfInvention | Detection method and apparatus for checking leaks of sealing products |
| abstract | The invention relates to a detection method for testing the leakage of sealed product packaging, characterized in that the detection method comprises the following steps: placing at least one product (2) previously sealed in an air, nitrogen or argon atmosphere in a In the chamber (3) (step 101); the pressure in the chamber (3) is reduced to a sub - vacuum pressure less than 10-1 mbar, while continuing to carry out the sub-vacuum pumping in the chamber (3), so that the The gas contained in the chamber is ionized in order to monitor at least one ionized gas from nitrogen, oxygen or argon of the gas volume contained in the sealing product (2) via analysis by emission spectrometry or mass spectrometry The concentration of the components is varied in the chamber (3) (step 102). |
