IR-3 workstation is a Digilabs UMA-500 Infrared Microscope is a single element detector FTIR microscope ideal for characterizing small and heterogeneous samples and is configured for the Mid-Infrared region only. This instrument is dependent on IR-2 to operate. Measurements can be made in transmission, reflection, attenuated total reflection (ATR), and grazing angle with this instrument. Methodologies that are most often conducted with this instrument are micro-sample measurements in; transmission, reflection, attenuated total reflection (ATR), grazing angle, cryogenic work and laser photolysis.

Applications

• Spectrum measurements (transmission, absorbance, reflection) over a wavenumber range of 7,500–450 cm¹ (1.3μm–22.0μm)
• Self assembled monolayer (SAM) characterization
• Synthesis characterization
• Reaction monitoring
• Materials analysis
• Defect and surface contamination analysis
• Laboratory instruction in spectroscopy
• Spectroscopic research experiments
• Micro cryogenic characterization of samples
• Micro laser photolysis
• Attenuated Total Reflection (ATR)
• Diffuse Reflection (DR)
• Grazing Angle (GR)

Configurations

• Beam Splitter
  • Extended range KBr (Mid-Infrared)
• Detector
  • Liquid Nitrogen cooled MCT-A (Narrow band 7,500–650 cm^-1)
• Source
  • Water-cooled SiC Ceramic (Mid-Infrared)
• Objectives
  • 4X visible light
  • 15X Cassegrain visible / infrared light
  • Grazing angle objective
• Additional
  • Slide-on Ge ATR accessory
  • 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

Specifications

• Spectral Range: 7,500-450cm^-1
• Maximum Resolution: 0.1 cm^-1

Note: Laser photolysis requires additional training. Please see Training for more information
