Each FT-IR bench has differentiating capabilities and features, and is supported with multiple detectors (InSb, mid and wide band MCT, DTGS) along with various standard and in-house designed accessories. Standard accessories include ATR (µ-ATR, flow-through ATR, circle cell), DRIFT (Harrick praying mantis with environmental chamber and Spectra-Tech), photo acoustic (MTEC 2000), and specular reflection (FT-80, variable angle). The laboratory is equipped with two vacuum systems for delivery of gases to various infrared and Raman cells. Two additional vacuum systems provide metal and organic film deposition capabilities.
