WebHelium gas is then introduced into the test piece, often in a 10% concentration. A Mass Spectrometer analyses a sample from the chamber as the vacuum continues to be drawn. The Mass Spectrometer measures the helium leakage and sets the pass/fail decision. http://www.leakdetection-technology.com/science/the-flow-of-gases-in-leaks/helium-bombing-test.html

WebTracer gas in leak detection (12 % of annual helium consumption) Helium is commercialized in many different purity levels from balloon gas with roughly 90 % of helium up to a purity of 6.0, which is 99.9999 % of helium. So which purity levels should one use for leak detection? Highest purity is rarely used in leak detection. WebVacuum Chambers for Leak Testing Sealed Parts Agilent Test Fixtures for Leak Detectors Used in conjunction with the Auto Sequencer mode of our Helium Leak Detector, a test fixture, also referred to as a flapper box, improves the efficiency of a sealed part test. Closing the spring-loaded lid automatically initiates the test. jww 移動 マウス
