IR-2 workstation is a Digilabs FTS-6000 is a step scanning FTIR that is configured for the Mid-Infrared region only. It is also the infrared source for IR-3 the UMA-500 Infrared Microscope. Measurements can be made in transmission, reflection, and attenuated total reflection (ATR) with this instrument. Methodologies that are most often conducted with this instrument are routine sample measurement, micro-sample measurements, fast TRS (Time Resolved Spectroscopy), cryogenic work and laser photolysis. The IR-2 workstation can also be fitted with a wide range of FTIR accessories to provide additional capabilities.

  • Additional
    • The attached UMA-500 Infrared Microscope
    • The spectrometer and sample compartment are purged with dry compressed air, which reduces the possibility of atmospheric water or CO2 contamination of the spectra and samples.
    • A wide range of sample compartment FTIR accessories are available
    • “Win IR-PRO” software for complete data collection and processing
