FIELD: test equipment.
SUBSTANCE: invention refers to tightness tests and can be applied in tests of closed containers filled with consumer goods. Method involves detection of at least one analyte (AN(P)) in the environs (A(P)) of container (3) filled with consumer goods (P) by mass-spectrometric analysis (10). The result of mass-spectrometric analysis is interpreted as a leak indication.
EFFECT: enhanced leak detection accuracy.
