When calibrating Fourier-transform infrared (FTIR) devices, polystyrene calibration sheets are frequently utilized. Polystyrene, a synthetic polymer with distinct absorption peaks in the mid-infrared spectrum, is used to make these films. The FTIR instrument can be calibrated to deliver precise and dependable findings for a range of analytical applications by using the polystyrene calibration film.

It is crucial to comprehend the significance of calibration in spectroscopic analysis before getting into the specifics of how to use the polystyrene calibration sheet for FTIR calibration. The process of creating a relationship between the measured signal and the amount or concentration of an object of interest is known as calibration. It compares the obtained spectrum to a recognized reference standard to guarantee that the instrument produces exact and accurate findings.

1.Film Placement: Place the polystyrene calibration film in the sample holder of the FTIR instrument. Ensure that the film is correctly aligned and does not overlap or wrinkle, as this may introduce artifacts into the calibration spectrum.

2.Spectral Acquisition: Acquire the spectrum of the polystyrene calibration film using the FTIR instrument. This can be done by selecting the appropriate settings, such as spectral range, resolution, and scan speed, based on the instrument's specifications and the desired level of accuracy.

3. Data Processing: Once the spectrum is acquired, process the data using the instrument's software or dedicated spectral analysis software. This step involves baseline correction, noise reduction, and normalization to ensure accurate and reliable results about Polystyrene Calibration Film for FTIR calibration mostly for calibration in Mohali.
