Leak finder for vacuum systems is explained and demonstrated in this short video. All you need is a spectrometer tuned for helium and a tank of helium. In order to find the leak, you need to expose the vacuum system locally to helium. If a leak is present then the gas is sucked inside and pumped out into the mass spectrometer. The beeping noise immediately alerts the user if helium has reached the spectrometer and the leak is found. The most common places for leaks are usually at the connections of the vacuum systems parts.

The quadrupole mass spectrometer (QMS) is used to detect and measure the abundance of gas phase ions. These ions have to pass between electrically connected rods in order to reach the detector. By combining alternating and direct voltage on these rods, it is possible to ensure that only ions with specific mass-to-charge ratio are capable of reaching the detector.
