Molecular Analysis – Thermo Fisher Nicolet iS20

Thermo Fisher Nicolet iS20

Sample Requirements

  • Non-aqueous liquid or solid
  • Must cover 2mm2 crystal

Summary of Technique

A sample is illuminated with infrared light, the absorption of which causes molecular vibrations in the sample. These vibrations are characteristic of functional groups in the sample. A representative spectrum is shown to the left with some of the evident functional groups denoted. FTIR is not able to determine connectivity of functional groups.

Information Provided & Detection Limits

FTIR-ATR is capable of rapidly determining the major organic chemical species present in a sample, with a detection limit of 1-5% by weight.
