The Vertex 70 FTIR spectrometer can measure in the mid-IR and far-IR region (4000-100 cm-1). Samples can be measured in transmission or via the ATR technique (diamond, germanium and zinc selenide crystals). The maximum resolution is 1 cm-1. The RAM II module is a FT-Raman module that is connected to the Vertex 70 FTIR spectrometer. The RAM II offers a spectral range within 3600-50 cm-1 (Stokes shift). The RAM II module is equipped with a standard 1064 nm laser excitation source (500 mW Nd:YAG laser) and a liquid-nitrogen-cooled high-sensitivity germanium diode detector. The maximum resolution is 2 cm-1.
