Helium is a highly inert gas found in nature in limited quantities. It is colorless, odorless, nonflammable & 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.
With the lowest boiling point of any gas (4.2 Kelvin or -269o Celsius), liquid helium is the coldest matter on Earth. This makes it deal as a cryogenic agent for a number of cutting-edge medical and physics applications. For Instance, It is used to cool superconductive magnetic coils in magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) medical equipment.
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 characteristic.
