What is Fourier Transform Infrared Spectroscopy (FTIR)?

Fourier Transform Infrared Spectroscopy (FTIR) is a form of spectroscopy that utilizes the interaction between infrared light and matter to identify molecular vibrations and specific functional groups characteristic to a given material. These characteristic molecular vibrations can be interpreted from a collected spectrum and used to identify a material.

What information can a Fourier Transform Infrared Spectroscopy (FTIR) Analysis Provide?

An FTIR analysis can qualitatively identify a material, even if the material is not a pure substance. This is useful for identifying foreign or unknown materials, mixtures, copolymers, and much more.

FTIR also has the ability to perform quantitative analysis and determine the percentage of a substance present in a mixture.

What Materials can be Analyzed Using Fourier Transform Infrared Spectroscopy (FTIR)?

A variety of materials can be analyzed including various organic materials, polymers, pharmaceuticals, foreign materials, powders, carbonates, phosphates, sulfates, nitrates and more. The FTIR system provides the highest performance available with a wide variety of sampling options to identify materials in a variety of states such as solid, liquid, or gas.

Accurate Results

The validation software ensures that the instrument is operating within the required specifications.

Please Note

FTIR samples submitted in plastic sandwich bags can become contaminated due to an inner non-stick coating. To prevent contamination of samples, Micron requests wrapping samples in aluminum foil prior to packaging.
