General
| Helium is a highly inert gas
found in nature in limited quantities. It is colourless,
odourless, non-flammable & non-toxic. Liquid Helium is the
coldest known substance with boiling point of -269 degree C.
Special transportation and storage equipment is required for
minimizing losses of the product. |
|
Applications
| Helium is the second element in
the periodic table and owing to its nonflammable nature &
lightweight, replaces Hydrogen in the metrological
applications. Helium is used in numerous other applications in
line with its highly inert & stable characteristics. Major
applications are as under: |
- Magnetic Resonance Imaging (MRI)
- Fibre Optics
- Balloon Filling
- Research & Development
|
- Deep Sea Diving
- Space Exploration
- Analytical Applications
- Leak Detection
