Detecting Leaks in Vacuum Systems

Leaks are the bane of vacuum systems. Leaks are one of the principal causes that inhibit the achievement of optimal base pressures. There are several approaches available to detect leaks of various sizes which do not involve expensive leak detection tools. In this course the methods to quantify leaks and a general approach to detection will be presented. In addition, specific techniques to detect leaks, in rough, medium, high and ultra-high vacuum will be detailed. The use of helium-based leak detectors as well as the use of residual gas analysis for finding very small leaks will also be highlighted.

Duration: 1 Hour(s)
