1.Neon is a rare atmospheric gas which is odorless, colorless, tasteless, nontoxic, monatomic and chemically inert. The concentration of Neon in the atmosphere, by volume percent, is 1.8 x 10-3.
2.Newradar's high purity neon in 5N were good in sales in the past year 2015 for export 400 cylinders
per month . The quality details as follows:

Applications:
1. Neon is often used in signs and produces an unmistakable bright reddish-orange light.
2. Neon is used in vacuum tubes , high-voltage indicators, lighting arresters,wave meter tubes,televsion
tubes,and helium-neon lasers.
3. Neon is used in some plasma tube and refrigerant applications but has few other commercial uses.
It is commercially extracted by the fractional distillation of liquid air.Since air is the only source, it is
considerably more expensive than helium.
