This bioactive ceramic is particularly used for its [biocompatibility](https://filab.fr/en/our-services/our-expertise-services/laboratory-biocompatibility-testing.md), strong mechanical properties, porous morphology and bioresorbability. ### What does ISO 13779-3 say? The **ISO 13779-3:2018** standard, entitled *“Implants for surgery — Hydroxyapatite — Part 3: Chemical analysis and characterization of crystallinity ratio and phase purity”*, specifies test methods for the chemical analysis, evaluation of the crystallinity ratio and phase composition of hydroxyapatite-based materials, such as powders, coatings or bulk products.   These tests are intended to describe material properties and facilitate communication between different organizations. They are not designed to replace a company’s functional and internal evaluation tests, although they may be used for this purpose.   ISO 13779-3:2018 introduces a new method for measuring the crystallinity ratio of hydroxyapatite and proposes the [Rietveld method](https://filab.fr/en/our-services/our-analysis-services/laboratory-material-testing/laboratory-analysis-using-the-rietveld-method.md) as an alternative for quantifying the content of foreign phases. ### Chemical analysis of medical devices Chemical analysis assessing the purity of hydroxyapatite (HAP) powders must meet the precise criteria set out in the NF ISO 13779-3 standard (available on the [www.boutique.afnor.org](https://www.boutique.afnor.org/) website).  To this end, the support of an analytical and testing laboratory enables you to carry out your industrial projects while ensuring the compliance of your products. In addition, FILAB offers analysis according to ASTM F1854 to study the porosity of an HAP coating on an implant.  ![résidus métaux lourds iso 19227](https://filab.fr/wp-content/uploads/elementor/thumbs/blog-DM-pvpgk9e63v2koonnqe1zmojnqgufbd0bhipoompeig.jpg) ## Our solutions: expert support and various analytical methods to characterize your HAP powders ### Why choose FILAB for HAP powder analysis? **The FILAB laboratory is accredited for the analysis of HAp powders used in surgical implants in accordance with ISO 13779-3.** With [state-of-the-art analytical equipment](https://filab.fr/en/our-technical-resources.md) and a qualified team of PhD holders and engineers, Filab laboratory analyzes and characterizes your HAP hydroxyapatite powders according to the NF ISO 13779-3 standard, through the following services: [Chemical analysis](https://filab.fr/nos-prestations/analyse/analysis-chimiques/) of the composition of HAP hydroxyapatite powders [Analysis and quantification of heavy metals by ICP AES / ICP MS](https://filab.fr/en/our-technical-resources/laboratory-analysis-icp-icp-ms-icp-aes.md) [Characterization and determination of the crystallinity level of hydroxyapatite powder by X-ray diffraction (XRD](https://filab.fr/en/our-technical-resources/x-ray-crystallography-laboratory-xrd.md)) Solubility testing of HAP hydroxyapatite powder [Coating characterization and SEM-EDX analysis](https://filab.fr/nos-moyens-techniques/laboratoire-d-analysis-par-microscopie-electronique-a-balayage-meb-edx/) [Analysis of cleaning residues (TOC and HCT) and detergents](https://filab.fr/nos-prestations/expertise/analysis-hct-cot/) Determination of the presence of [foreign phases](https://filab.fr/en/our-services/our-expertise-services/laboratory-biocompatibility-testing/determination-of-the-presence-of-foreign-phases-in-your-powders-by-xrd.md) (alpha-TCP, beta-TCP, CaO and TTCP) by [XRD](https://filab.fr/en/our-technical-resources/x-ray-crystallography-laboratory-xrd.md) [Morphological characterization of particles and powders using a morphogranulometer](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization/morphological-characterization-morphogranulometer.md) Ca/P ratio measurement [Quantification of metallic trace elements by ICP AES / ICP MS](https://filab.fr/en/our-technical-resources/laboratory-analysis-icp-icp-ms-icp-aes.md) Detection of oxyapatite by FTIR infrared spectroscopy [Particle size analysis of powders by laser diffraction](https://filab.fr/en/our-services/our-analysis-services/laboratory-granulometric-analysis.md) [Cleaning process validation](https://filab.fr/nos-prestations/expertise/analysis-hct-cot/) [Surface area analysis and measurement by BET](https://filab.fr/en/our-technical-resources/laboratory-analysis-bet.md) analysis according to ASTM F1854 To support you under the best possible conditions, the FILAB laboratory is accredited [Research Tax Credit (CIR)](https://filab.fr/en/filab-cir-approved-analysis-laboratory.md).
