Helium Leak Detection Technology
Since helium is lighter than air it has a molecular weight of 4 and air has a molecular weight of 30 if introduced into an empty pipe with a break in it the helium gas molecules will exit from the opening rise through the subsurface and exit from the ground at the exact point where the break is.
Helium leak detection technology. In effect provides verification of package integrity. Leak detection associates seal integrity monitoring system sims model 1915 helium based leak testing system features an oil free pump detector and integrated power system that is designed for the needs of the pharmaceutical and medical device industries enabling quantitative analysis of package systems at sensitivity levels as low as 1 x 10 10 cc s at room temperature. Helium leak detectors are the ideal solution for leak detection and leak tightness testing under vacuum. The detection range of helium in vacuum tests lies between 10 2 and 10 13 pa m 3 s.
Outgassing issues do not affect the method tests can be performed regardless of chamber condition. The test gas helium is safe and a small light molecule which is suitable for detecting micro leaks. Laco s family of leak testing solutions covers a wide range of leak testing methods including helium leak testing air leak testing non helium tracer gas leak testing and other leak testing methods to meet the needs of our customers. Vacuum chambers and process systems.
Select a leak test method below to learn more and to find product solutions associated with the test method. The ability to quickly pinpoint the location and relative magnitude of the leak less time is spent making repairs. Helium leak detection technology is used to confirm the presence or absence of channels and or holes in packages. We offer the most sensitive comprehensive testing on the market which means we can pinpoint the exact location of the tiniest leaks.
Leak detection technologies is the industry leader for compliance testing and leak location for pipelines and storage tanks. For clean research applications hld configurations employ clean dry quiet scroll vacuum pumps. Hld helium leak detectors are rugged precise and easy to use instruments that accurately and efficiently detect leaks in an array of industrial applications. A helium leak detector also known as a mass spectrometer leak detector msld is used to locate and measure the size of leaks into or out of a system or containing device.
Helium leak detection is extremely accurate quantitative and repeatable. The theory behind helium gas detection is rather simple. The tracer gas helium is introduced to a test part that is connected to the leak detector.
