How do you purify Krypton?

Answer 1

Liquefy it by cooling and reducing pressure and then do fractional distillation.

Answer 2

Krypton purification typically involves fractional distillation or cryogenic distillation. These methods separate krypton from other gases by exploiting differences in boiling points or by cooling it to temperatures where it becomes a liquid, and then collecting the purified krypton.

Answer 3

Krypton is separated from air by fractional distillation.
