Mohammad Khodaei

Dear Shahnaz

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.

Thankx sir

I agree with Mohammad Khodaei
