Supplementary data: Assessing the Validity of a Calcifying Oral Biofilm Model as a Suitable Proxy For Dental Calculus

FTIR analysis data on a calcifying oral biofilm model. Includes metadata, raw data and images of spectra. <em>README.md</em> file included in <em>ftir_raw-data.zip</em>.<br><strong>FTIR analysis: </strong>A few ug of each sample were repeatedly ground together with KBr and pressed in a 7 mm die under two tons of pressure using a Specac mini-pellet press. Samples were analysed at the Laboratory for Sedimentary Archaeology, Haifa University. The analysis was conducted with a Thermo Nicolet is5 spectrometer intransmission, at 4 cm&lt;sup&gt;-1&lt;/sup&gt; resolution, with an average of 32 scans between wavenumbers 4000 and 400 cm&lt;sup&gt;-1&lt;/sup&gt;.本数据集为钙化口腔生物膜模型的傅里叶变换红外光谱（FTIR）分析数据，包含元数据、原始光谱数据及光谱图像。<em>README.md</em>说明文件包含于<em>ftir_raw-data.zip</em>压缩包中。 <strong>傅里叶变换红外光谱分析：</strong>每份样品取数微克，与溴化钾（KBr）反复研磨混合后，使用Specac微型压片机将混合物置于7毫米模具中，以2吨压力压制成片。样品分析工作于海法大学沉积考古学实验室完成。本次分析采用赛默飞尼高力is5（Thermo Nicolet is5）光谱仪以透射模式进行，光谱分辨率为4 cm⁻¹，在4000至400 cm⁻¹波数范围内采集32次扫描并取平均。
