On the interference of Kr during carbon isotope analysis of methane using continuous-flow combustion–isotope ratio mass spectrometry [PDF]
Stable carbon isotope analysis of methane (δ13C of CH4) on atmospheric samples is one key method to constrain the current and past atmospheric CH4 budget.

Krypton assay in xenon at the ppq level using a gas chromatographic system and mass spectrometer [PDF]
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.

Clathration of Volatiles in the Solar Nebula and Implications for the Origin of Titan's atmosphere [PDF]
We describe a scenario of Titan's formation matching the constraints imposed by its current atmospheric composition. Assuming that the abundances of all elements, including oxygen, are solar in the outer nebula, we show that the icy planetesimals were ...

Runaway electrons during subnanosecond breakdowns in high-pressure gases
The parameters of runaway electrons produced in nanosecond high-voltage discharges in different gases (air, nitrogen, sulphur hexafluoride, krypton, argon, methane, neon, hydrogen, helium) at atmospheric and higher pressure were studied.

High-Pressure Reactivity of Kr and F2—Stabilization of Krypton in the +4 Oxidation State
Since the synthesis of the first krypton compound, several other Kr-bearing connections have been obtained. However, in all of them krypton adopts the +2 oxidation state, in contrast to xenon which forms numerous compounds with an oxidation state as high

The possibility for gamma and UV radiation detection based on electrical breakdown time delay measurement in krypton and xenon filled diodes [PDF]
The paper presents results of electrical breakdown time delay mean value t¯d as a function of relaxation time τ (memory curve) for krypton and xenon-filled diodes at 270 Pa pressure.

Automated Sampling System for Monitoring 85Kr in Air
Radioactive krypton-85 (85Kr) gas, a chemically inert and non-proliferation indicator, is derived from fission products. Its detection relies on the Budesamt für Strahlenschutz–Institute of Atmospheric Radioactivity (BfS-IAR) method, which necessitated ...
