Spectrometer : Perkin Elmer Spectrum 100
Detector : DTGS
Spectral range : 7000 to 400 cm -1
Analysis mode: Transmission, Reflection
Sampling accessory : ATR diamond, KBr pad, ZnSe support
Resolution : 16 to 1 cm- 1 .
This spectral analysis makes it possible to know the nature of the covalent bonds present in the sample.
Each of them (for example carbon-oxygen) will be characterized by one or more bands on the IRTF spectrum obtained.
The interpretation of these bands in relation to their intensity, their wavelength, their shape as well as the comparison with a library of reference spectra (more than 15,800 spectra), will make it possible to highlight at least the chemical family (ester, acid, urethane ...) and very often the exact nature of the compound analyzed.
Fast & simple,
Requires little sample (a few µg),
No sample preparation,
No separation (Response on a single spectrum)
Identification of chemical functions allowing the determination of the nature of the sample, but difficulty sometimes going back to the exact structure
