Fundamentals of Helium Leak Testing Solutions


Part 1 | May 13 | 2:00 - 3:00 PM EDT
Part 2 | May 20| 2:00 - 3:00 PM EDT

Mass spectrometer helium leak testing originated during the atomic bomb era in high-energy physics. However, today this technology has evolved into wide market applications in High Vacuum Technology, Semiconductor, Automotive, Aerospace, Pharmaceutical, Metallurgy, and many other diverse markets. Helium leak testing is used to measure the integrity of vacuum systems to high production testing of individual components. Helium mass spectrometer testing offers both qualitative and quantitative leak test solutions with high accuracy and the highest sensitivity test method available.

This two-part seminar covers the science of helium mass spectrometer leak testing and the fundamentals required to offer the best total solution.

Highlights are focused on various leak test techniques with their limitations, and how to select the proper leak test solution. Completion of this seminar provides the necessary tools so that you can choose the proper leak test solution.


  • How a helium mass spectrometer works and why.
  • Why use Helium or Hydrogen tracer test gas and the limitations.
  • Mass Spectrometer leak testing versus other methods of leak testing.
  • Inboard vacuum versus outboard sniffing methods.
  • Understanding internal and external helium calibrated leaks for a better test.
  • What do the leak rate numbers really mean and the reality of them.
  • Vacuum technology applied to helium leak testing.
