The difference and application analysis between helium detection in vacuum tank and RGA residual gas analysis

Vacuum tank helium inspection and RGA Residual Gas Analysis are two commonly used vacuum system inspection methods, which have some differences in principle and application. Residual Gas Analysis (RGA), also known as Internal Moisture Analysis, or IVA(Internal Vapor Analysis).

How it Works:
Vacuum tank helium detection: Vacuum tank helium detection is by placing the object to be detected in the vacuum tank, injecting helium and conducting leak detection. If there is a leak, helium will escape from the leak and be detected by helium detectors.

RGA: RGA is a germplasm analysis technique to obtain relevant information by analyzing the composition of residual gases in a vacuum system. The RGA instrument ionizes the gas in the vacuum system and analyzes and detects the mass to charge ratio of the gas ions.

Applications:
Vacuum tank helium test: Vacuum tank helium test is mainly used to detect the leakage of welded joints and seals in vacuum environment. It is widely used in aerospace, electronic devices, optical equipment and other fields.

RGA: RGA is mainly used to analyze the gas composition in the vacuum system, which can detect and analyze the type, content and possible pollution sources of the gas. It is widely used in semiconductor manufacturing, material research, vacuum equipment maintenance and other fields.

The difference and application analysis between helium detection in vacuum tank and RGA residual gas analysis

Detection range:
Vacuum helium inspection: Vacuum helium inspection is mainly concerned with leakage problems and can detect small leak defects or cracks.

RGA: RGA can analyze and detect various gas components in vacuum systems, including common gases, water vapor, organic matter, etc.

To sum up, there are some differences in principle and application between helium detection in vacuum tank and RGA. Vacuum helium inspection is mainly used to detect leakage problems, while RGA is used to obtain relevant information by analyzing the gas composition in the vacuum system. The two methods have their own application value in different fields.
