Our Valuable Clients

<p><strong>PURPOSE:</strong> <u>Polystyrene Calibration Film</u> is meant for the calibration of Fourier Transform Infrared (FTIR) Spectrometer which is being routinely used in the chemical and pharmaceutical industry.</p>
<p>All the available similar Polystyrene Calibration Films are imported and secondary standards.</p><p></p><p>Only the <strong><u>NIST Standard Reference Material® 1921b, PhEur 2.2.24, PhJap 2.25, NPL UK, and NPL India</u>,</strong> for Polystyrene Calibration Standard Films from corresponding National Metrological Institution, are the original suppliers of Primary Standards.</p>
<p>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.</p>
<p><strong>Our Polystyrene Calibration Standard</strong><br><br>Films are available mounted on 2” x 4” cards that fit in the standard universal slide mount in all spectrophotometers.</p><p></p><p>This Polystyrene Calibration film is under development, we took the initiative to produce this in India to supply it in our India&nbsp;to give this Polystyrene Calibration Film at a very affordable price to our Indian Industry.</p>

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.
