Heliumleckagetest
Heliumleckagetest is a method used to detect and quantify leaks in sealed systems. It is a highly sensitive technique that utilizes helium gas as a tracer. Helium is chosen because it is a small, inert, and non-toxic gas that can easily penetrate even very small openings. The test typically involves introducing helium into the system being tested. A helium detector, often a mass spectrometer, is then used to scan the exterior of the system for any signs of helium escaping. The mass spectrometer is particularly effective at identifying the specific mass-to-charge ratio of helium ions, allowing for precise detection even in the presence of other gases. The rate at which helium is detected indicates the size and severity of any leaks present. Heliumleckagetest is widely employed in various industries, including aerospace, automotive, and medical device manufacturing, where ensuring the integrity of sealed components is critical. It is also used in vacuum technology and for testing pipelines and storage tanks. The procedure can be performed in different configurations, such as a sniffer test, where the detector is moved along the outside of the system, or a vacuum test, where the system is placed in a chamber and the surrounding atmosphere is analyzed for helium. The sensitivity of the heliumleckagetest makes it an invaluable tool for quality control and safety assurance.
