WebInfrared (IR) spectroscopy by ATR is applicable to the same chemical or biological systems as the transmission method. One advantage of ATR-IR over transmission-IR is the limited path length into the sample. This avoids the problem of strong attenuation of the IR signal in highly absorbing media such as aqueous solutions. WebJan 1, 2024 · DRS-FTIR is found to be a simple, highly sensitive and a direct analytical method for the determination of antibiotics in food samples as compared to the other analytical techniques such as GC–MS, HPLC, LC/MS–MS, HPLC-UV and spectrophotometry.
