The Fundamentals of Vacuum Leak Detection
For the case where the test is carried out with helium mass 4 at a pressure difference of 1 bar from the atmosphere pressure (external) to the vacuum (p < 1 mbar, internal), which is frequently found in practice, the designation "helium standard leak rate" has been introduced. In order to indicate the rejection rate for a test using helium ...

Leak Testing
Helium leak detection is a process used to measure the size of cracks, holes, and leaks in the product or system being tested. A leak detector (also known as a mass spectrometer or MSLD) is used to conduct the testing. The Mass Spectrometer pumps out the atmosphere in the test piece or the vacuum chamber, creating negative pressure.

Why Use Helium for Leak Testing?
Perhaps the biggest factor that makes helium an ideal tracer gas for leak testing is its low atmospheric concentration (5 ppm). This low concentration allows designers to configure testing equipment that can detect leaks below 10-9 atmcc/sec in vacuum applications and below 1 x 10-6 atmcc/sec in sniffing or atmospheric …
