Helium Leak Testing Basics
At the heart of helium leak testing is a mass spectrometer dedicated to quantifying trace amounts of helium within any sampled train of atmosphere. A helium leak mass spectrometer can resolve extremely small leaks. For example, this equipment can detect a leak small enough to fill just two cubic centimeters of helium (or the amount equal to two sugar cubes) in 320 years. This level of detection is critical for many different processes; from simply finding the sources of gas contaminants in a vacuum system to calibration of assembly-line detection equipment in the refrigeration compressor manufacturing industry.
Helium is an inert gas that is nearly absent in normal atmospheres, in contrast to hydrogen which is readily produced in enormous quantities when pressures within stainless steel systems are brought to UHV levels. Benefits of using helium as a trace gas include:
- Only modestly present in the atmosphere (roughly 5 parts per million)
- Flows through cracks 2.7x faster than air
- User Friendly
Due to these attributes, and its high sensitivity, helium leak testing has gained broad acceptance in a wide range of leak testing applications. There are two generally accepted methods to helium leak testing: Spray Probe, and Sniffer Probe.
Spray Probe Leak Testing: Provides Maximum Sensitivity
For this technique, the leak detector is hooked directly to the system under test and the inside of the system is evacuated. Once an acceptable vacuum is achieved, helium is sprayed discreetly on the outside of the system, with particular attention being paid to any suspect locations. Any leaks in the system, including defective welds (caused by cracks, pin holes, incomplete welds, porosity, etc.), flawed or missing gaskets, leaks due to loose clamps, or any other defect will allow helium to pass and be readily detected by the machine. The source of any leaks can then be accurately pinpointed and repaired.
The spray probe process is used to achieve the highest level of sensitivity. The equipment being used dictates the maximum sensitivity achievable; in Jurva Leak Testing’s case it is 2x10-10 std cc/sec. This technique does require that the system being tested is relatively leak tight prior to testing, as an ample vacuum is required for testing. However, by using special throttling devices a gross test can typically be performed. The gross test should eliminate any major leaks, permitting the use of increased sensitivity. The following are examples of systems that we test using the spray probe technique:
- A-bar furnaces
- E-beam systems
- Laser systems
- Metal deposition equipment
- Distillation systems
- Vacuum systems
For this technique, helium is purged throughout the inside of system being tested. Due to the innate properties of helium it readily migrates throughout the system and in its attempt to escape penetrates any imperfections, including: defective welds (caused by cracks, pin holes, incomplete welds, porosity, etc.), flawed or missing gaskets, leaks due to loose clamps, or any other defect. The system’s exterior is then scanned by using a probe attached to the leak tester. Any leaks will result in an increased level of helium nearest the source and be readily detected. Leak sources can then be pinpointed, providing the opportunity for immediate repair and retest.
Unlike the spray probe technique, this process is very flexible and can be adapted to meet the needs of any virtually any system in which helium can be injected. There is no practical size limitation. The sniffer probe technique is not as sensitive as the spray probe process, however, due to the amount of helium present in the air (approximately 5 ppm). The maximum sensitivity achievable under this procedure is approximately 1x10-6 std cc/sec. Nevertheless, this process is vastly superior to other traditional leak testing methods, such as: bubble testing, acoustic emission, liquid penetrant or vacuum box testing.
