Figure 1From: Correction of spike contribution for strontium isotopic measurement by thermal ionization mass spectrometry: a test for spike-standard mixed solutions Plots of corrected 87 Sr/ 86 Sr as a function of 84 Sr/ 86 Sr and weight fractions of the spike. Plots of corrected87Sr/86Sr as a function of84Sr/86Sr and weight fractions of the spike. Solid and dashed lines represent an average 87Sr/86Sr and 2 σ standard deviation of the unspiked standard data, respectively. Error bars are based on within-run 2 σ standard error.Back to article page
