| Abstract | The largest comparison of analytical techniques that are useful for calcium phosphate analysis has been conducted, presenting recommendations for quality control and research of calcium phosphates. Results from three classical quantification methods (gravimetry, titrimetry, photometry) and three instrumental measurement methods (XRF, FAAS ICP-OES) are reported to determine the most accurate, fastest and cheapest analysis method. Remarks are given about increasing the accuracy for each method, and corrections are made for adsorbed water. For routine analysis, a recommendation is given to ICP-OES for a fast analysis together with a less frequent use of gravimetry to validate the results and provide a periodic cross-check. |
