Our Valuable Clients
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.
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
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.
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.
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.
