WebWhat is the difference between ATR and KBr? Actually, both techniques, are used for functional groups analysis. FTIR mainly used for powder analysis, in this technique the samples are mixed with KBr powder as matrix (holder). While ATR are used for surface analysis without any extra materials or holder.

You’ll also find that the ATR method gives a lot of interference below 600 wavenumbers, which results in it only being practical to measure down to 650 cm-1, whereas with the KBr disc method one can go down to 450 cm-1.

techniques spectroscopy, KBr Spectra vs ATR Spectra
WebApr 14, 2024 · Attenuated Total Reflectance is based on the measurement of internally reflected IR beam through multiple internal reflections from the crystal- sample interface. The beam is directed to the base plate of the crystal which is in intimate contact with the sample (liquid or solid powder). On each reflection the beam enters a few micron … WebThe difference between the two spectra results from ion exchange between chloride ions and bromide ions when a hydrochloride sample is diluted by KBr. While not shown here, the single-reflection ATR … WebYou can initiate novel ATR, Raman and NIR modules at the touch of a button, enabling access to these techniques without manually changing system components.
