SPECTROMÈTRE IRTF PERKIN ELMER SPECTRUM 100

Principle

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.

Advantages

Quick & easy,
Non-destructive technique,
Requires little sample (a few µg),
No sample preparation,
Very sensitive.

Disadvantages

No separation (response on a single spectrum)
Identification of chemical functions allowing the nature of the sample to be determined, but difficulty in sometimes tracing the exact structure
