Understanding Helium Gas Analyzers for Vacuum Chamber Applications
Helium gas analyzers are essential instruments used primarily in vacuum chamber applications to detect leaks and ensure the integrity of sealed environments. These analyzers are particularly effective due to helium’s unique properties: it is a small, light molecule that can easily escape through minute openings, making it an ideal tracer gas for leak detection. The operation of a helium gas analyz

[Leak Detection] The Influence of Different Gases and Pressures on Vacuum Leak Rates
Currently, most standard leak standards specify their leakage rates under helium gas conditions at an inlet pressure of 100 kPa. In this study, a constant-volume变压法 was employed to calibrate a standard vacuum leak with a rated leakage of 2.3 × 10⁻⁶ Pa·m³/s, measuring its leakage rates for three gases—hydrogen (H₂), helium (He), and deuterium (D₂)—at various inlet pressures. Prior to the measurements, the system was preheated to remove residual gases, allowing us to determine the system's background leakage rate. We also investigated how this background leakage might affect the accuracy of the calibrated leak rates. Furthermore, by integrating insights from both viscous flow and molecular flow theories, we examined how different gases and varying inlet pressures influence the leakage characteristics of the standard leak.
