PURPOSE:Polystyrene Calibration Film is meant for the calibration of Fourier Transform Infrared (FTIR) Spectrometer which is being routinely used in the chemical and pharmaceutical industry.
All the available similar Polystyrene Calibration Films are imported and secondary standards.
Only the NIST Standard Reference Material® 1921b, PhEur 2.2.24, PhJap 2.25, NPL UK, and NPL India, for Polystyrene Calibration Standard Films from corresponding National Metrological Institution, are the original suppliers of Primary Standards.
So traceable standards are only Secondary Standards, and traceability to a particular organization of a corresponding country also is condemnable, because traceability is only for measurements and their units like wave numbers for %transmission or Absorbance for Polystyrene Calibration Film.
Our Polystyrene Calibration Standard
Films are available mounted on 2” x 4” cards that fit in the standard universal slide mount in all spectrophotometers.
This Polystyrene Calibration film is under development, we took the initiative to produce this in India to supply it in our India to give this Polystyrene Calibration Film at a very affordable price to our Indian Industry.
Frequently Asked Questions
What is Polystyrene Calibration Film?
The certified values are intended for use in calibrating the wavelength/wavenumber scale of spectrophotometers in the infrared (IR) spectral region from 3.2 μm to 18.5 μm (540 cm-1 to 3125 cm-1).
A unit consists of a matte finish polystyrene film approximately 38 μm thick with a 25 mm diameter exposed area, centered 38 mm from the bottom of a cardboard holder, which is 5 cm × 11 cm × 0.2 cm in size.
Why is polystyrene film used in IR calibration?
The ubiquitous use of FT-ER instruments has led to the need to establish a wavelength scale compatible with its high resolution. From the beginning of infrared spectroscopy, it was realized that a stable material for the calibration of spectrometers was required.
A number of materials were suggested including polystyrene, 1,2,4-chlorobenzene, toluene, and other compounds. Among these materials, polystyrene proved the most useful and is often used for the calibration of infrared spectrometers.
Why is polystyrene a problem?
It has a long life of hundreds of years for natural decay, so a returnable policy is implemented for proper disposal according to local governance policy.
