Diffure reflectance (DRIFTS): This sampling technique collects and analyzes scattered IR energy. The sample is placed in a sample cup (grinded and mixed with KBr), typically in powder form. The amount of KBr in the sample cup is typically 70-95%.
Transmission: The beam travels through a sample and then impinges the detector.
We also have available an in-situ cell which can be heated.
There are two detectors available:
DTGS (Operates in room temperature): Cuts off at around 400 cm-1
MCT (Operates with liquid nitrogen cooling): Faster and less noisy than the room temperature detector. Cuts off at around 700 cm-1
