Since that time there have been many technological advances and alterations to best practice in the measurement and interpretation Tue May 10, 2022. helium Standard Leak Rate . Halogen and helium leak detection; Hydrostatic Leak Testing Hydrostatic testing is the preferred leak-testing method and perhaps the most often used. Acoustical leak detection is widely used in testing high pressure lines, ductworks etc. Water is a much safer fluid test medium than air because it is nearly incompressible. Particle count testing is performed at a specified velocity, flow rate, or Reynolds Number. The programmable helium conservation modules for Agilent 8890, 8860, and 7890 GC systems are used to switch the carrier gas stream from helium to nitrogen when the instrument is idle, which can significantly reduce helium usage..
