We describe a new chemical separation method to isolate Ca from other matrix elements in biological samples, developed with the long-term goal of making highprecision measurement of natural stable Ca isotope variations a clinically applicable tool to assess bone mineral balance. A new two-column procedure utilizingHBr achieves the purity required to accurately and precisely measure two Ca isotope ratios (44Ca/42Ca and 44Ca/43Ca) on a Neptune multiple collector inductively coupled plasmamass spectrometer (MC-ICPMS) in urine.
