Vacuum Chamber Technique for Gas Leak Detection: A Step-by-Step Guide

Introduce a specimen into a water-filled chamber and securely seal it with a lid. Activate the gas switch to supply compressed air to the Venturi, thereby establishing a vacuum connection with the chamber. Utilize a gas regulator to finely adjust the level of vacuum required for the specimen's environment. As a result of the pressure difference inside and outside the chamber, any gases present in the headspace will escape. This can be observed by the continuous release of bubbles from the affected region.
