- •
Ca phosphates can be distinguished with ToF-SIMS using Bi3+ cluster ions and PCA.
- •
Ca/P ratios obtained by EDS and XPS measurements are systematically too low.
- •
XPS measurements prove that there is no decomposition of hydroxyapatite by X-rays.
- •
No surface segregation effect was observed for the investigated Ca phosphates.
