The numbers in parentheses indicate the position according to peak height (see Additional file 1, Figure S1). (DOC 122 KB) 13007_2010_132_MOESM3_ESM.DOC Additional file 3:Table S2 - Absorption band assignments of the first (PC1), second (PC2), third (PC3) and fourth (PC4) factor ...
Peak assignment to the different functionalities was done based on literature [15], [16], [56], [58], [59], [60], [61]. Baseline correction, using the R package {baseline} [62], was applied to the whole spectrum (from 4000 to 400 cm−1), so the distortions caused by optical ...
(FTIR) to estimate the firing temperature of clay-containing remains. The method is based on the finding that the infrared absorptivity of fired clay minerals, measured at the Si–O–Si stretching resonance band, is negatively correlated with firing temperature. Moulds and mould cores dating to ...
Si 4.4 3.7 4.2 4.0 Ti 6.4 3.5 4.2 4.0 Fig. 7 shows the FTIR data of welding fumes generated by flux cored wires. Major peaks in welding fumes sample FC1 are at wavenumbers 586, 894, 983, 1042, 1361, 1537, 1653 cm−1. The peak at wavenumber 894 cm−1 is due to the O...

Table 2 Dust deposition during and after haze use Full size table As can be seen, there is very low measureable deposition of dust during haze use. The haze droplets are so small (0.2 µm), that they would not be expected to be detectable with the system used, which has a minimum ...
Peak positions recorded for all spectra are available in Additional file 1. Table 4 Case study object spectral matches for polymer identification Full size table FTIR module and sampling techniques With the ATR module, the spectral absorbance intensity was significantly higher for clamped measurements ...

The HazMatID Elite FTIR instrument library did not report a match to DMDNB, and the measured spectrum (SI Fig. S7) showed significant differences to the measured spectrum of 98% DMDNB solid (SI Fig. S1). None of the peak frequencies in the sample match those described for DMDNB (Table ...
