HMT Inspection offers Helium Mass Spectrometer Leak Testing services. HMT inspection utilizes a Varian 959 Porta-Test Leak Detector with Macro Torr configuration which provides high test pressure capability and is excellent for fast response sniffing applications.
HMT is capable of performing leak-detection services on single bottom above ground storage tanks (AST), double bottom ASTs, floating roof pontoons, and select piping systems.
The use of helium as a tracer gas is advantageous because it is nonflammable, and it quickly diffuses through small leak paths. In addition, it is nonreactive with other chemicals. Due to its minute molecular size and its low concentration in the atmosphere (5ppm), very small leaks may be detected.
