MASS SPECTROMETER FOR DETECTING LEAKAGES VIA A TRACER GAS

Abstract

The present invention relates to a mass spectrometer (10) for detecting leakages via a tracer gas, said spectrometer (10) comprising: - an ionising means (3) intended to ionise said tracer gas; - at least one magnetic-field source (501) that generates a magnetic field (I) that is dependent on the electric current I supplied to said source (501) and that is intended to sort ionised elements; - a means (7) for detecting said tracer gas once ionised; characterized in that said spectrometer comprises a means (II) for adjusting the magnetic field, said adjusting means being configured to allow at least two separate adjustments, said adjustments having different sensitivities.
