Tree-rings are recorders of environmental signals and are therefore often used to reconstruct past environmental conditions. In this paper, we present four annually resolved, multi-centennial tree-ring isotope series from the southeastern Tibetan pla

13C/12C variations of organic carbon have been investigated in forest soil down to a depth of 40 cm by using a fast method of sample preparation. The measured values of the various soil horizons are in good agreement with measurements applying the cl

Oxygen is quantitatively separated from oxygen-nitrogen gas mixtures by gaschromatography and adsorbed at a molecular sieve at liquid nitrogen temperature. After the desorption of oxygen from the molecular sieve the liberated oxygen can be converted
