Krypton and xenon are generated from the air, with natural concentrations of 1 ppm for krypton and 87 ppb for xenon. Both are collected as secondary products from air separation units during low-temperature air separation. Air separation units utilize low-temperature distillation to separate air components based on their boiling points. This is a common method for producing oxygen, nitrogen, argon, as well as rare gases such as neon, krypton, and xenon.
