Introduction
An FTIR machine is a vital analytical instrument widely used in laboratories and industrial applications to study the molecular composition of materials. Fourier Transform Infrared (FTIR) spectroscopy provides precise information about chemical bonds, functional groups, and molecular structures, making it an essential tool for research, quality control, and material characterization.
Industries such as pharmaceuticals, polymers, environmental science, and chemical manufacturing rely on FTIR machines for accurate identification and verification of substances. Its ability to analyze ftir machine solids, liquids, and gases adds versatility and convenience to laboratory workflows.
How FTIR Machines Work
FTIR machines operate on the principle that molecules absorb specific frequencies of infrared light corresponding to the vibrations of their chemical bonds. The absorbed wavelengths produce a unique spectral pattern that acts as a “fingerprint” for the material being analyzed.
The main steps include:
- A broadband infrared light source emits radiation toward the sample.
- The sample absorbs specific wavelengths based on its molecular composition.
- A detector captures the transmitted or reflected light.
- Fourier Transform algorithms convert the raw interferogram data into a readable spectrum.
- The resulting spectrum is analyzed to identify functional groups, chemical bonds, and material composition.
FTIR spectroscopy allows for qualitative and quantitative analysis, providing detailed insights into the chemical makeup of a sample.
