The PIKE FlexIR Hollow Waveguide Accessory is an excellent tool for remote and specific area analysis of a wide variety of samples in the mid-infrared region. Visible surface contamination, small area material identification and bulky materials too large to fit into the FTIR sample compartment are a few of the many samples and application types for the FlexIR accessory. The FlexIR also is ideal for reaction monitoring. Available probes include ATR, diffuse reflection, and specular reflection.
