Krypton assay in xenon at the ppq level using a gas chromatographic system and mass spectrometer [PDF]
Eur. Phys. J. C (2014) 74:2746, 2013 We have developed a new method to measure krypton traces in xenon at unprecedented low concentrations. This is a mandatory task for many near-future low-background particle physics detectors. Our system separates krypton from xenon using cryogenic gas chromatography. The amount of krypton is then quantified using a mass spectrometer.

Neuroprotective Effects of Krypton Inhalation on Photothrombotic Ischemic Stroke [PDF]
BiomedicinesThis is the first in vivo study to investigate the neuroprotective effects of krypton on focal cerebral ischemia. The aim of the study was to analyze the effect of 2 h of inhalation of a krypton–oxygen mixture (Kr 70%/O2 30%) on the recovery of ...

Clathrate hydrates as a sink of noble gases in Titan's atmosphere [PDF]
, 2007 We use a statistical thermodynamic approach to determine the composition of clathrate hydrates which may form from a multiple compound gas whose composition is similar to that of Titan's atmosphere. Assuming that noble gases are initially present in this gas phase, we calculate the ratios of xenon, krypton and argon to species trapped in clathrate ...

Protonated Clusters of Neon and Krypton [PDF]
Journal of the American Society for Mass Spectrometry, 2019 We present a study of cationic and protonated clusters of neon and krypton. Recent studies using argon have shown that protonated rare gas clusters can have very different magic sizes than pure, cationic clusters. Here we find that neon behaves similarly to argon, but that the cationic krypton is more similar to its protonated counterparts than the ...

Measurements of the Secondary Electron Emission from Rare Gases at 4.2K [PDF]
arXiv, 2013 Dependence of the secondary electron yield (SEY) from the primary beam incident energy and the coverage has been measured for neon, argon, krypton and xenon condensed on a target at 4.2K. The beam energy ranged between 100 eV and 3 keV, the maximal applied coverage have made up 12000, 4700, 2500 and 1400 monolayers correspondingly for neon, argon ...
