  • FTIR Sample Techniques  Transmission | Thermo Fisher

    FTIR Sample Techniques Transmission | Thermo Fisher

    The user simply places a sample directly into the infrared (IR) beam. As the IR beam passes through the sample, the transmitted energy is measured and a spectrum is generated. However, the analyst must often prepare the sample into a pellet, mull, film, etc. before the transmission measurement can be made.

  • FTIR Sample Techniques: Attenuated Total Reflection ATR

    FTIR Sample Techniques: Attenuated Total Reflection ATR

    An ATR accessory operates by measuring the changes that occur in an internally reflected IR beam when the beam comes into contact with a sample. An IR beam is directed onto an optically dense crystal with a high refractive index at a certain angle. This internal reflectance creates an evanescent ...
