Helium
Helium is the second-lightest element in the universe, and it is the only element that is a liquid at absolute zero. The appearance is a colorless, odorless, and tasteless gas. It is also non-toxic and non-flammable.
Helium is a versatile gas with a wide range of applications. It is use in a variety of industries, including cryogenics, welding, aerospace, semiconductors, fiber optics, medical, and other applications.
Helium 99.999%, also known as grade 5.0 helium or UHP grade, offers unmatched purity, making it the go-to choice for precise and sensitive leak testing. With its purity level, this helium variant is virtually free from impurities, ensuring accurate and reliable results during leak detection processes. Its high purity eliminates the risk of false positives or false negatives, providing confidence in detecting even the smallest leaks.
Application
Helium is use in a variety of industries, including:
- Cryogenics: It is use as a coolant in cryogenic applications, such as MRI machines and particle accelerators.
- Welding: It is use as an inert gas in welding applications to prevent oxidation of the weld joint.
- Aerospace: The gas is use as a lifting gas in balloons, airships, and satellites.
- Semiconductors: Helium is use in the production of semiconductors to create a clean and inert atmosphere.
- Fiber optics: It is use in the production of fiber optic cables to create a low-loss transmission medium.
- Medical: It is use in medical applications, such as MRI machines and ultrasonic imaging.
Helium 99.999% purity finds extensive use in leak testing applications across a wide range of industries. Whether it’s pipelines, storage tanks, pressure vessels, or complex industrial systems, this high-purity gas serves as a versatile tracer gas. Its low molecular weight and inert properties allow it to quickly and effectively locate and identify leaks in both pressurized and vacuum systems.

Helium 99.999% is a high-purity gas that is used for leak detection in a variety of industries. it is an ideal gas for leak detection because it is:
- Inert: The gas does not react with other materials, so it will not contaminate the system being tested.
- Light: It is the lightest gas in the universe, so it will easily flow through small leaks.
- Sensitive: The gas can be detected at very low concentrations, so even small leaks can be easily found.
