What is infrared spectroscopy?

Infrared (IR) spectroscopy is an analytical technique that uses the infrared portion of the electromagnetic spectrum to identify and study chemicals. A sample is exposed to infrared radiation, and the absorption and transmission of the radiation are measured. The resulting IR spectrum, which plots absorption versus frequency, provides a unique 'fingerprint' of the sample. It is commonly used to identify substances, determine their structure, and quantify the amount of a specific component in a mixture across diverse fields like chemistry, materials science, and environmental monitoring.

What other technologies are related to infrared spectroscopy?

infrared spectroscopy Competitor Technologies

mass spectrometry

Mass spectrometry is an analytical technique used to identify the chemical composition of a sample by measuring the mass-to-charge ratio of ions. It provides complementary but also competing information for compound identification compared to infrared spectroscopy.

infrared spectroscopy Complementary Technologies

gas chromatography

Gas chromatography separates volatile compounds, often before they are identified via infrared spectroscopy. This separation can simplify complex spectra and allow for the analysis of individual components in a mixture. Thus, it is complementary to IR spectroscopy.

HPLC

HPLC separates compounds in a liquid mixture, and can be used as a front end to IR spectroscopy, especially for non-volatile or thermally labile compounds. This enhances the information that can be extracted from the IR analysis.
