Helium Leak Detection Agilent

WebA trace of hydrogen or helium with the nitrogen will enable leaks to be found at a lower pressure. A suitable electronic detector must be used – your standard detector is not sensitive to hydrogen or helium. Nitrogen can be supplied with a trace of hydrogen (as shown in the photo) or helium specifically for leak testing. Use a reference leak to WebThe mass spectrometer method with helium and the radioactive gas (Krypton-85) method are the most sensitive, but the latter requires special safety precautions. Leak testing is widely used on pressure vessels and vacuum systems in situ, or a specimen can be placed inside a gas-filled enclosure and then tested for inward leaks. city of burleson logo
