Hydrogen and helium were used as collision/reaction gases for ICP-MS isotope ratio measurements of calcium and potassium in order to avoid isobaric interference with the analyte ions from (mainly) argon ions 40Ar+ and argon hydride ions 40Ar1H+. Mass discrimination factors determined for the isotope ratios 25Mg/24Mg, 40Ca/44Ca and 39K/41K under optimized experimental conditions varied between 0.044 and 0.075. The measurement precisions for 25Mg/24Mg, 40Ca/44Ca and 39K/41K were found to be 0.09%, 0.43% and 1.4%, respectively. This analytical method that uses ICP-QMS with a collision cell to obtain isotope ratio measurements of magnesium, calcium and potassium was used in routine mode to characterize biological samples (nutrient solution and small amounts of digested plant samples). The mass spectrometric technique was employed to study the dynamics of nutrient uptake and translocation in barley plants at different root temperatures (10 degrees C and 20 degrees C) using enriched stable isotopes (25Mg, 44Ca and 41K) as tracers. For instance, the mass spectrometric results of tracer experiments demonstrated enhanced 25Mg and 44Ca uptake and translocation into shoots at a root temperature of 20 degrees C 24 h after isotope spiking. In contrast, results obtained from 41K tracer experiments showed the highest 41K contents in plants spiked at a root temperature of 10 degrees C. 000060856 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000060856 588__ $$aDataset connected to Web of Science, Pubmed 000060856 650_7 $$2WoSType$$aJ 000060856 65320 $$2Author$$acalcium 000060856 65320 $$2Author$$aisotope ratio measurements 000060856 65320 $$2Author$$aICP-QMS 000060856 65320 $$2Author$$amagnesium 000060856 65320 $$2Author$$anutrient uptake and transport 000060856 65320 $$2Author$$aoctopole collision 000060856 65320 $$2Author$$areaction cell 000060856 65320 $$2Author$$aplants 000060856 65320 $$2Author$$apotassium 000060856 65320 $$2Author$$atracer experiments 000060856 7001_ $$0P:(DE-Juel1)VDB28681$$aFüllner, K.$$b1$$uFZJ 000060856 7001_ $$0P:(DE-Juel1)VDB68545$$aSeeling, U.D.$$b2$$uFZJ 000060856 7001_ $$0P:(DE-HGF)0$$aFornalczyk, G.$$b3 000060856 7001_ $$0P:(DE-Juel1)129349$$aKuhn, A.
