The δ values regarding the working standard glacier water obtained because of the calibrated sensor system is basically exactly the same as the IRMS dimension results with an extremely high calibration accuracy from 0.17‰ to 0.75‰. Preliminary outcomes from the reproducibility measurements display a typical deviation of 0.13‰ for δ18O, 0.13‰ for δ17O, and 0.64‰ for δ2H,
