Krypton in today's atmosphere is somewhat heavier than solar krypton, and the krypton embedded in meteorites known as carbonaceous chondrites is even heavier than that.

The same fractionation process that could turn a solar sample of xenon into a modern - day atmospheric sample of xenon would leave a deficit in light isotopes of krypton, compared with what is found in Earth's present atmosphere.

In the samples of mantle gas taken by Holland and his colleagues, the krypton measurements were heavy, producing «something that looks rather like gases that are trapped in primitive chondrites today,» Pepin sayIn the samples of mantle gas taken by Holland and his colleagues, the krypton measurements were heavy, producing «something that looks rather like gases that are trapped in primitive chondrites today,» Pepin sayin primitive chondrites today,» Pepin says.

«And the diagnostic clue is that all of the isotope ratios for neon, argon, krypton, xenon, nitrogen, what have you, look as if they have suffered an escape process in which the lightest isotope escaped preferentially relative to the heavier ones» — a process called fractionation.

«It so happens that if you bring a solar component in and mix it with that fractionated krypton, you get the present atmospheric composition,» Pepin explains.

Inert gases such as neon (Ne), helium (He), and krypton (Kr) and other constituents such as nitrogen oxides, compounds of sulfur, and compounds of ozone are found in lesser amounts.

Severinghaus discovered that xenon and krypton are well preserved in ice cores, which provides the temperature information that can then be used by scientists studying many other aspects of the earth's oceans and atmosphere over hundreds of thousands of years.

The final step in collecting xenon or krypton gas would be to put the MOF material under a vacuum, which sucks the gas out of the molecular cages for safe storage.

To capture xenon and krypton, conventional technologies use cryogenic methods in which entire gas streams are brought to a temperature far below where water freezes — such methods are energy intensive and expensive.

Other tests also showed that in the absence of xenon, SBMOF - 1 captures krypton.

To capture xenon and krypton, conventional technologies use cryogenic methods in which entire gas streams are brought to a temperature far below where water freezes - such methods are energy intensive and expensive.
