Fourier Transform Infrared Spectroscopy Analysis

Fourier Transform Infrared Spectroscopy Analysis

Fourier transform infrared spectroscopy (FTIR) is a technique that has been used over the years in chemical analysis for the identification of substances and is one that may be applied to the characterization of microorganisms. FTIR also offers a high-efficiency approach for drug characterization, especially in drug release, because of its high spectral resolution and fast acquisition times. BOC Sciences can provide a range of analytical services based on FTIR.

Advantages of Fourier transform infrared spectroscopy (FTIR)

Compared with other detection methods and technique, the FTIR technique is more convenient, efficient, non-destructive, low cost, and label free. Given its advantages of short determination time and high precision and its capabilities of multi-index simultaneous, continuous, and non-damage determination, FTIR has been widely used in drug research and included in many national pharmacopoeia as a legal method.
