The invention concerns a detection method for checking sealed product packages for leaks, characterized in that it comprises the following steps: at least one previously sealed product () is placed in an air, nitrogen, or oxygen atmosphere, in a chamber () (step), the pressure in the chamber () is lowered to a secondary vacuum pressure below 10mbar and, while continuing the secondary vacuum pumping of the chamber (), the gases contained in the chamber are ionized to monitor the change in the chamber () of the concentration of at least one gaseous species of the gas volume contained within the sealed product () chosen from among nitrogen, oxygen, or argon, by analysis by optical emission or mass spectrometry (step).

A treatment device for transport and storage boxes according to the invention comprises a plurality of decontamination modules (-) supported by a common chassis () and arranged in a row of at least one column () of modules superposed one on top of the other. Each decontamination module (-) comprises its own pumping means () having at least a primary pump () housed in a primary pumping compartment () that is longitudinally offset from the decontamination chamber (). Access to the decontamination modules (-) is had via side access doors which are all oriented on one and the same access side and which are acted upon by actuating means that automatically close and open them. A lateral transfer zone is provided on the access side, and comprises a robot () capable of moving the transport and storage boxes between a frontal loading-unloading station () and the decontamination chambers () of each of the decontamination modules (-). The amount of space occupied by and the throughput of the treatment device () are thus optimized.
