For more information about leak detection test methods, see Leak detector compendi-
um on the website www.pfeiffer-vacuum.com.
4.3.1 Hard vacuum test
● Part that can be connected to pipe and placed under a vacuum
● Part that can be placed in a vacuum chamber
Spray method This method involves removing the air from the part to be tested, connecting it to the de-
tector's analyzer cell, then spraying tracer gas on the points of the part that are likely to
leak. The detector measures the flow of tracer gas that penetrates due to part leakage.
