METHOD AND DEVICE FOR TESTING A CONTAINER FOR LEAKS

摘要

The invention relates to a method for testing a container for leaks, comprising: a first step in which a background noise in a chamber at atmospheric pressure is measured by a sensor of traces of volatile organic compounds with a sensitivity of less than or of the order of 1 ppb, and an intermediate step of decontaminating the internal atmosphere of the container when the measure of background noise is above a given threshold and a second step during the which the internal atmosphere of the container is mixed such as to homogenise the atmospheric composition, containing a container defining a bounded internal space in which a volatile organic compound is present, using the trace sensor of volatile organic compounds, which step includes comparing the background noise reading with the reading of the concentration of volatile organic compound, so that any leak from said container under test is detected. The invention also relates to a corresponding device.
