Importance of Helium Mass Spectrometer Leak Detector in Combination Products . The Mass Spectrometer Leak Detector is a system used for localization and measuring leaks inside or outside a product. This method uses tracer gas – helium, which is used to fill up the product connected to a detector.
Helium Leak Detection Solutions | Leak Testing Solutions
To loe helium leaks you would usually either spray or sniff, the latter being the norm in a high volume testing situation, to detect the rise in helium gas concentration, parts can be tested inside a shroud where the test pressure is at or near atmospheric pressure, the air is circulated inside the shroud and passes by a mass spectrometer in sniffing mode, alarms can be preset to minimise ...
Helium Leak Detection
Helium Leak Detection has become the standard method for identifying condenser airinleakage and condenser tube leaks. With the ability to "pinpoint" leakage it takes the guess work out of the older methods such as using smoke, shaving cream and ultrasonic guns. This results in the ability to quickly make repairs creating faster turnarounds for the facility. For condenser airinleakage and ...

Sniff Testing With Helium | VES
· Most modern leak detectors will have a selectable sniff test function making them very versatile tools in a production setting. Gas flow is delivered to the mass spectrometer where helium molecules are ionised and accelerated toward a current detector, on route they are deflected via an electromagnet. The amount of deflection is based upon ...
Ultimate Guide to Vacuum Leak Detection
The spectrometer itself works in the following way: any helium molecules flowing into the spectrometer will be ionized, and these helium ions will then "fly" into the ion detector, where the ion current is analysed and recorded. Before reaching the detector, the ions have to pass a magnetic field which deflects all ions other than helium ones. Based on the ionization current, the leak rate ...

Helium leak test, Helium mass spectrometer : 네이버 블로그
Helium leaks out of the container, and the rate of the leak is detected by a mass spectrometer. Helium is used as a tracer because it penetrates small leaks rapidly. Helium has also the property of being nontoxic, chemically inert and present in the atmosphere only in minute quantities (5 ppm ). Typically a helium leak detector will be used to ...
LEAK DETECTION
At the origin of the helium leak detection method was the "Manhattan Project" and the unprecedented leaktightness requirements needed by the uranium enrichment plants. The required sensitivity needed for the leak checking led to the choice of a mass spectrometer designed by Dr. Nier [5] tuned on the helium mass (see the tracer gas definition above). Because of its industrial use ...
