Short summary

Air in polar ice cores provides information on past atmosphere and climate. We present a new method for simultaneously measuring eight gases (CH₄, N₂O and CO₂ concentrations; isotopic ratios of N₂ and O₂; elemental ratios between N₂, O₂ and Ar; and total air content) from single ice-core samples with high precision.
