Fourier Transform Infrared Spectrometer (FTIR)
Fourier Transform Infrared Spectrometer (FTIR) (Product Code: SCI-304/07) is a single-beam infrared spectrometer used to identify organic and inorganic materials from their infrared absorption spectra in research, quality-control and university laboratories. It measures from 7,800 to 350 cm-1 at a maximum resolution of 0.4 cm-1, using a sealed Michelson interferometer, a Ge/KBr beam splitter and a Peltier-controlled DLaTGS detector. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of the laboratory analytical instruments it offers.

What Is an FTIR Spectrometer Used For?
An FTIR spectrometer shows which chemical bonds and functional groups a sample contains, so it is used to identify unknown substances, confirm the identity of pharmaceutical and polymer raw materials, check product purity and follow reactions. The interferometer collects all wavelengths at once and a Fourier transform converts the result into a spectrum that can be compared with reference spectra. In universities it is a core instrument for organic chemistry, materials science and research projects.
Install the spectrometer in a dry, temperature-stable room, because KBr optics are sensitive to humidity. Use the nitrogen purge to reduce water-vapour and carbon-dioxide bands, and record a fresh background before each sample series. Keep the sample compartment clean and closed when the instrument is idle.
What to Specify When Ordering
- Detector: standard DLaTGS, or the optional MCT detector for higher-sensitivity work
- Whether you need the optional 10 Hz rapid-scan function
- Whether the infrared microscope functions described above are required in your configuration
- The computer set-up for USB 2.0 connection, and the number of instruments and delivery destination
