PerkinElmer Software -First take a background spectrum with the empty tube inside the FTIR spectrometer.-This will automatically save a background transmittance. Add 2-3 drops of HCl to the tube and reinsert it into the FTIR. In the top left corner set the wavenumber from 3500 cm-1 to ...
Reach the peak of productivity Generate fast, reliable answers with less effort—even in busy, multi-user QC labs or teaching labs—with our compact, powerful FTIR spectrometers from the name you trust in FTIR: Nicolet. Today’s busy QA/QC and teaching laboratories demand fast answers with ...
1(C) that the chocolate adulterated with lard shows almost similar functionality and peak pattern as compared to pure lard oil, which confirmed the presence of lard adulteration in these chocolate samples. However, the adulterated chocolate was palm oil based therefore, the comparative FTIR spectra ...
For the peak analysis results shown in Figs. 4 and 6, integration limits and baseline points are listed in Table 1. Spectra were not pre-processed before integration; however, limits of integration were chosen to exclude the contribution of other urine components, and a suitable baseline was ch...
