In this study the following biomaterials were analysed by means of Fourier transform infrared vibrational spectroscopy (FTIR); they are: reabsorbable Dac Blu, non reabsorbable Dac Blu, non reabsorbable atomized Dac Blu, non reabsorbable fine Dac Blu, reabsorbable Biocoral 450, Calcitite 2040-12, Orthogel, Apagen, BTF 65, Calcitite 4060-2 Osprogel, Bio-Oss, Biostite, Osprovit, Merck Hydroxyapatite. The analysis was performed with a Jasco 5300-FTIR. At 64 readings for spectrum with a 2 cm-1 resolution. By means of this method it has been possible to perform a structural study at a molecular level of the commercial products mentioned before. The analysis showed which of the samples examined had lost the apatite OH- group during production. It also allowed the identification of some of the hydroxyapatites examined as carbonate apatites. Finally, it allowed the identification and quantification of the organic substances in the examined products.
在本研究中，采用傅里叶变换红外振动光谱法（FTIR）对以下生物材料进行了分析；它们是：可吸收的Dac Blu、不可吸收的Dac Blu、不可吸收的雾化Dac Blu、不可吸收的细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。分析使用的是Jasco 5300 - FTIR。光谱以2 cm⁻¹分辨率进行64次读数。通过这种方法，得以在分子水平上对上述商业产品进行结构研究。分析表明，所检测的样品中哪些在生产过程中失去了磷灰石OH⁻基团。它还能鉴定出所检测的一些羟基磷灰石为碳酸磷灰石。最后，它能鉴定并定量所检测产品中的有机物质。
