FTIR pellets, commonly used in Fourier-transform infrared spectroscopy, typically have a diameter range of 3 mm to 13 mm. The exact size required depends on the specific FTIR equipment manufacturer, as different instruments may have varying sample holder dimensions and specifications. This size range ensures compatibility with most FTIR spectrometers and allows for consistent and accurate spectral analysis.

Key Points Explained:

1. Diameter Range of FTIR Pellets:

   • FTIR pellets are generally manufactured to fall within a diameter range of 3 mm to 13 mm. This range is standardized to accommodate the sample holders of most FTIR spectrometers.
   • The size ensures that the pellet fits securely in the sample holder, allowing for proper alignment and consistent spectral measurements.

2. Dependence on FTIR Equipment Manufacturer:

   • The exact size requirement for FTIR pellets can vary depending on the manufacturer of the FTIR equipment. Different brands and models may have specific sample holder dimensions, which dictate the optimal pellet size.
   • For example, some FTIR spectrometers may require pellets closer to the lower end of the range (3 mm), while others may accommodate larger pellets (up to 13 mm).

3. Importance of Pellet Size in FTIR Analysis:

   • The size of the pellet is critical for ensuring accurate and reproducible results in FTIR spectroscopy. A pellet that is too small may not cover the entire beam path, leading to incomplete or inconsistent spectral data.
   • Conversely, a pellet that is too large may not fit properly in the sample holder, potentially causing misalignment or damage to the equipment.

4. Practical Considerations for Purchasers:

   • When purchasing FTIR pellets, it is essential to consult the equipment manufacturer's specifications to determine the optimal size for your specific FTIR spectrometer.
   • Standardizing pellet size within your laboratory can also streamline sample preparation and improve the consistency of results.

By adhering to the recommended size range and considering the specific requirements of your FTIR equipment, you can ensure reliable and accurate spectroscopic analysis.
