FTIR instruments have distinct advantages over dispersive spectrometers:
1. Better speed and sensitivity.
2. Internal laser reference. The use of a helium neon laser as the internal reference in many FTIR systems provides an automatic calibration.
3. Increased optical throughput.
4. Simpler mechanical design.
5. Elimination of stray light and emission contributions.

What is the source of FTIR instrument?
Don't know, but go on Wikipedia, it will tell you.
Range resolution of FTIR?
I always use 400 - 4000cm-1.
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
Where is a carbonyl group detected by FTIR?
At around 1700-1800 [1/cm]
Why NaCl is not used in FTIR?
It is used but not after wavelengths higher than 15 micrometres.
What is range for FTIR?
FTIR or Fourier transform Infared spectroscopy is the simultaneous collection of spectral data in the wide spectral range.Which has quite an advantage over a dispersive spectrometer which only covers a narrow range of wave lengths at once.
Types of soil test?
macro and micro mutrients test in soil through FTIR
Thermo fisher scientific model ftir nicolet 6700?
this is an equipment used to perform DRIFT analyses
What is the principle of FTIR?
The principle of FTIR is based on the fact that bonds and groups of bonds vibrate at characteristic frequencies. A molecule that is exposed to infrared rays absorbs infrared energy at frequencies which are characteristic to that molecule. In a molecule, the differences of charges in the electric fields of its atoms produce the dipole moment of the molecule. Molecules with a dipole moment allow infrared photons to interact with the molecule causing excitation to higher vibrational states. Diatomic molecules do not have a dipole moment since the electric fields of their atoms are equal. During FTIR analysis, a spot on the specimen is subjected to a modulated IR beam. The specimen's transmittance and reflectance of the infrared rays at different frequencies is translated into an IR absorption plot consisting of reverse peaks. The resulting FTIR spectral pattern is then analyzed and matched with known signatures of identified materials in the FTIR library.
Why you use polystyrene film in calibration of ftir?
It gives all conestent values in any temperature.it is stability more in any temperature
What do Arab Muslims eat at eid ul ftir?
They eat all kinds of allowed (or halal) food. Refer to question below for details of halal food.
Which solvents are used in IR spectroscopy?
Cyclohexane is used as a solvent for xylene FTIR. Some other solvents used are hexane, diethyl ether, acetone etc. depending on the type of analyte.
