Abstract (en)

[origin: WO2006009442A2] The invention relates to a method for detecting a leak in a package at least partly filled with a gas, comprising the steps of exposing a package to a reduced pressure, measuring the concentration of the gas in the vicinity of the package, comparing the measured concentration to a limit value, and emitting a signal when the measured value exceeds the limit value. The concentration measurement does not herein have to take place simultaneously with the exposure to the reduced pressure, but a sample can for instance be taken from the vicinity of the package, the gas concentration of which sample is measured over a longer period of time. The invention further relates to a leak detecting device for performing this method, provided with means for exposing the package to a reduced pressure, means for measuring the concentration of the gas in the vicinity of the package, means connected to the measuring means for comparing the measured gas concentration to a limit value, and means connected to the comparing means for emitting a signal when the measured value exceeds the limit value. The measuring means can herein comprise an NDIR gas detector.
