FTIR Analysis of Chemical Extracts

Fourier-transformed infrared (FTIR) spectrophotometry was employed to determine chemical changes among the extracts and their fractions [32 (link)]. FTIR spectra were recorded in a Bruker FT-MIR model Vertex 70 V spectrometer. Wave number range was set in the range of 800 to 4000 cm⁻¹. Samples were blended with KBr and compressed into disks. FTIR spectra analysis was carried out by using Omnic 7.1 software (Thermo Fisher Scientific, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
