How much does an infrared spectrometer cost?
Spectrometers that are used in pure research or high-end applications in academia or large corporations. These instruments perform sophisticated tasks such as IR imaging of cells, or biopsies and inspections of semiconductors. Depending on the bells and whistles, these instruments can cost more than $100,000.
What is dispersive infrared spectrophotometer?
Dispersive infrared instruments are sometimes called grating or scanning spectrometers. This grating is similar to a prism. It separates the wavelengths of light in the spectral range and directs each wavelength individually through a slit to the detector.
Why is FTIR preferred over dispersive IR?
FTIR spectrometers have several prominent advantages: (1) The signal-to-noise ratio of spectrum is significantly higher than the previous generation infrared spectrometers. (2) The accuracy of wavenumber is high. Due to these advantages, FTIR Spectrometers have replaced dispersive IR spectrometers.
What are the four advantages of FTIR over dispersive IR?
The benefits of upgrading to an FTIR from an existing dispersive infrared instrument will be immediately evident in spectral quality, data collection speed, reproducibility of data, and ease of maintenance and use.
Is IR spectroscopy expensive?
An IR spectrum is something that is easy to do; it’s direct; and it’s non-expensive.
How much does FTIR analysis cost?
For routine analysis, the price of an FTIR ranges from $15,000 to $20,000.
What is a dispersive spectrometer?
Dispersive spectrometers use either a prism or grating to spatially spread a spectrum of incident radiation across a detector array. In a dispersive imaging spectrometer, depicted conceptually in Fig. 7.1, the spectrum is dispersed in one direction, while the image is relayed in an orthogonal direction.
What is dispersive spectrometer?
As the name suggests, dispersive spectrometers generate spectra by optically dispersing the incoming radiation into its frequency or spectral components, as illustrated in the figure below. Common dispersive elements include prisms and gratings.
What is the advantage of interferometer over dispersive spectrometer?
In FTIR spectroscopy, the use of an interferometer instead of a dispersive monochromator offers many advantages: 1. Dramatically improved optical throughput due to a slit-free optical design, resulting in a high signal-to-noise ratio (Jacquinot’s advantage).
Is FTIR destructive?
Recently, Fourier transform infrared spectroscopy (FTIR) has been recognized as an important non-destructive analytical technique for the quantitative and qualitative analysis of inorganic ions in aerosols [16,17,18,19,20]. The advantage of FTIR technique is that it is non-destructive and less labor intensive.
What was the first infrared spectrophotometer ever made?
In this spirit, Shimadzu developed its first double beam self-recording infrared spectrophotometer: the AR-275. The instrument became commercially available in 1956 and was robust enough even for export overseas. In this 60th IR celebration year, Shimadzu launched the AIM-9000 FTIR microscope and failure analysis system.

What are the parts of a Fourier transform infrared spectrophotometer?
A Fourier transform infrared spectrophotometer consists of five basic parts — the infrared radiation source, the interferometer, the sample, the detector and the computer. The infrared radiation source usually is a glowing black-body source, and the amount of energy emitted is controlled by an aperture.
