Krypton is isolated from liquified air in a process called fractional distillation.
Krypton is isolated from liquified air by a process called fractional distillation.
It was found the year to be 1898, it was discovered in the air. I searched krypton on Wikipedia.org, "The World's Encyclopedia" the had a complete article on it.
Krypton is a noble gas, and as such is not reactive. Apart from keeping it isolated for whatever purposes you have for it, I doubt that it would require anything special.

Krypton (the element, not the mythical planet) has no purpose that I know of. It just is.
The only such elements are the Noble Gases (He, Ne, Ar, Kr, Xe, Rn) (that is helium, neon, argon, krypton, xenon and radon)
Krypton light has a large number of spectral lines, and krypton's high light output in plasmasallows it to play an important role in many high-powered gas lasers
We see solid and liquefied krypton used in some experiments, but most of the uses of krypton employ its gaseous phase. Use the related link to see how this inert gas is used.
it can be used for light and insulation
This depends on the application.

Like most of the the other rare gases, the main commercial use of Krypton is in a variety of light bulb applications including fluorescent, incandescent, gas discharge, gas glow, flash tube and laser lamps. Its bright and nearly white light output in high temperature plasma makes it valuable for photography and "neon" sign applications.
