For comparison the FTIR spectrum of the Sar-chelator by itself is also included. The conjugation of the sarcophagine cage to the ELP was indirectly confirmed by attenuated total reflection-Fourier transform infrared (ATR-FTIR). Figure S1 shows a comparison between the FT-IR absorbance spectra of...

SpectrumOne。 1.3 光谱的采集 扫描范围为4500~600cm -1 ,扫描次数设为 16次,分辨率为4cm -1 。 1.4 测试步骤 1.4.1 扫描背景谱图 由于傅里叶红外光谱仪是单光束仪器,故在采 集样品谱图之前通常需先采集背景。 将ZnSe晶体空置,在扫描窗口下的“Scan”对 话框中选择“Background”,扫描得到背景谱图。 —...
The time of analysis was substantially shortened and simplified (samples directly put on an ATR crystal and 30 s are needed for each spectrum acquisition) compared to the conventional biochemical methods for each component. The proposed models were generic or multi-species insofar as 29 species ...
An ATR-FTIR spectrum at 8 cm−1 resolution was collected with Impact 410 FTIR (Thermo Fisher Scientific, Madison, WI, USA) (Figure 8.2). The developed model had an R-value ranging from 0.87 to 0.94 and an error of 16–23 ppm. Ninety per cent of spinal cord-containing samples were ...
