Figure 1: Calibrated data for all samples. Calibrated measurements using the 2-point calibration for all of the 15 samples. Black data points denote calibrated values and their standard deviation for d18O, dD, d-excess (permil) and delta17O (permeg) vs. sample number.
Standards:
1. VSMOW2 (dD: 0.00±0.30 permil, d18O: 0.00±0.02 permil, d17O: 0.00±0.06 permil)
2. SLAP2 (dD: -427.50±0.30 permil, d18O: -55.50±0.02 permil, d17O: -29.70±0.04 permil)
Standard VSMOW2 chosen for zero-point and SLAP2 for slope correction.
Standard VSMOW2 at vials 1 8 15
Standard SLAP2 at vials 4 11 18
Figure 2: Instrument drift during run: Drift of the raw measurements of the calibration standard during the run for d18O (top row) and dD (bottom row) for each of the 2 calibration standards. Red solid and dashed lines show the average value of the standard and its standard deviation which has been used for calibration of the entire run period.

Figure 3: Correction of raw measurements. In sequence, the panels show the correction of the raw isotope measurements for the dependency of the spectroscopy of dD, d18O and d17O on water concentration in the cavity for each injection. The bottom panel shows the deviation of the water concentration from the reference value at 20000ppmv raw water concentration of the used instrument. The correction function was determined from detailed laboratory tests at FARLAB.
