Helium leak detector works on the principle of field mass spectrometer. The electric beam in the filament of the analysis tube ionizes the leaking helium gas. The ions are accelerated by increased voltage, escape through the split and later pass through the analyzer's magnetic field. The collector can only catch the helium ions and detect ...

Minimize "dead" volume and surface area for hard vacuum testing to increase performance in all aspects. Avoid conductance constraints for hard vacuum testing—it may decrease cycle times and increase sensitivity. Optimize helium test concentration to minimize expense—air dilution on test mixture can save on cost.

This process involves pressurizing the system or having a component tested with a helium gas mixture. This is then followed by specialized helium leak detectors that are used to sense and measure the helium that escapes from any leaks. By analyzing the amount and concentration of helium, technicians are able to find the exact location of the leak.
