Abstract
A method of, and apparatus for, detecting leaks from a surface provides a sampling device (10) making use of an air curtain (C). The body (11) of the device (10), the curtain (C) and a surface (B) to be tested together define a sampler volume (S). Pressure in the sample volume (S) is regulated to draw signal gas from a source thereof to the volume (S) along leak path (L) which exists. Sampled gas is withdrawn from the volume for checking by means of a mass spectrometer (18) for the presence of signal gas.
