Abstract:
1. A method for leak testing a container filled with a consumer product, comprising the step of monitoring presence in the surrounding of said container of at least one analyte that is not helium, the material composition thereof being dependent from said consumer product and exploiting a result of said monitoring as a leak indication, said monitoring comprising mass spectrometry, wherein the method comprises inline testing up to each container of a stream of said containers, and further comprises: providing subsequent containers of said stream within respective rest test chambers moved as a test chamber stream and controllably time multiplexing an operational gas stream-connection from the interiors of said test chambers to an input port to a single arrangement performing said mass spectrometry by controllably connecting each of said test chambers, moved as a test chamber stream, to a respective output line, providing at least two collector chambers which are distinct from the test chambers, moving said collector chambers into gas stream communication with respective ones of said output lines and collecting in said at least two collector chambers a dose of gas from respective different ones of said output lines, providing an input line to said mass spectrometry, sequentially moving one of said collector chambers after the other of said collector chambers with said respectively collected dose into gas stream communication with said one input line to said mass spectrometry and dispatching sequentially one of said doses after the other into said input line.
