polystyrene film made by polymer of styrene,
it is highly durability.
polystyrene film is all bands executed which cover whole IR
Region.

Most people are only using FTIR for identification, so
wavelength accuracy is most important.
A polystyrene film is an easy way to calibrate the entire
wavelength range of the instrument. The film produces
sharp absorbance bands at known wavelengths (or
frequencies) which can be used to verify that the
instrument's spectrum is accurate.
And also additionaly other than polystyrene we can use any
other reference material which is having known sharp
absorbence bands at different wavenumbers.
concept is calibrating the instrument against known
material and known results.
