In this work we analyze the following biomaterial: biomaterials used in this study are: reabsorbable Dac Blu, non reabsorbable Dac Blu, non reabsorbable atomized Dac Blu, non reabsorbable thin Dac Blu, reabsorbable Biocoral 450, Calcitite 2040-12, Orthogel, Apagen, BTF 65, Calcitite 4060-2, Osprogel, Bio-Oss, Biostite, Osprovit, Merck Hydroxiapatite. The quantitative XRF analysis was performed by a Philips PW 1480 with Rh tube. This research, besides underlining the possibility of applying the XRF method to the analysis of biomaterials. This study, shows the facility and the rapidity in the preparation of samples and standards in the form of tablets to undergo the analysis: furthermore the study shows the possibility of verify the analysis on the same sample in the future, because the tablet if well conserved, does not deteriorate. We can also verify a good analytic accuracy both for the principal elements (Ca, P) and for trace elements. The analyses show a moderate variability in the Ca/P ratio in the hydroxylapatites, and a greater variability in the secondary and trace elements.
在本研究中，我们分析了以下生物材料：本研究中使用的生物材料有：可吸收的Dac Blu、不可吸收的Dac Blu、不可吸收的雾化Dac Blu、不可吸收的薄型Dac Blu、可吸收的Biocoral 450、Calcitite 2040 - 12、Orthogel、Apagen、BTF 65、Calcitite 4060 - 2、Osprogel、Bio - Oss、Biostite、Osprovit、默克羟基磷灰石。定量X射线荧光光谱（XRF）分析由配备Rh管的飞利浦PW 1480进行。本研究除了强调将XRF方法应用于生物材料分析的可能性外，还展示了制备用于分析的片剂形式的样品和标准品的便利性和快速性：此外，该研究还表明未来有可能对同一样品进行分析验证，因为如果保存良好，片剂不会变质。我们还可以验证对于主要元素（钙、磷）和微量元素都有良好的分析准确性。分析表明，羟基磷灰石中钙/磷比存在适度变化，而次要元素和微量元素的变化更大。
