Bruker VERTEX-70LS FTIR and Hyperion 2000

 

The Bruker VERTEX-70LS FTIR is an extremely versatile research-grade step-scan spectrometer operating in the mid- and far-IR spectral regions. A variety of sampling options are available with the VERTEX FTIR bench, including a Bruker Hyperion 2000 FTIR microscope. The advanced Hyperion 2000 microscope is a part of the tool that equipped with an automated x, y-stage for line scans and mapping applications. It has optics for both transmitted and reflected light, is equipped with a mid-band MCT A detector (liquid nitrogen cooled, 7000-600 cm-1 spectral range), and has facilities for image and video capture with visible light via a frame grabber. The Pike MIRacle single bounce attenuated total reflectance accessory (ATR, ZnSe IRE) with automatic purging of the optical path allows for fast and simple analysis of solids, liquids, pasts, gels, and other materials.  It has a temperature controlled liquid cell with variable path length (6 mm to 1 mm) and programmable temperature controller.  The system also has a Manning Applied Technologies PM-100 polymer stretcher and modulator for 2D/3D FTIR correlation spectroscopy and rheooptical studies on perturbed polymer films. The stretcher is equipped for temperature control up to 70 o C (TC-100 controller) and can supply a strain amplitude of 0-0.6% (0-75 mm) at up to 70Hz with programmable waveforms.

Technical Specs:

Detectors:

  • Extended range KBr and multilayer beamsplitters (10,000-400 and 680-30 cm -1, respectively) detector
  • Liquid nitrogen cooled MCT (12,000-600 cm -1 ) detector
  • FIR DLATGS (700-10 cm -1 ) detector
Sampling accessories are:
  • A pellet press and wig-l-bug for KBr pellets
  • Transmission cells for mulls and neat liquids
  • A step-scan interferometer and internal digital signal processing which can be used for time-resolved FTIR spectroscopy with a resolution of 5 msec, with either an internal or external trigger, and with phase or amplitude modulation Ultraviolet-visible-NIR spectra in one shot.
Objectives:
  • ATR (Ge, 20x)
  • Grazing angle (with polarizer)
  • 15x IR/vis (for transmitted and reflected light)
  • 4x vis.
Other Accessories:
  • Pike MIRacle single bounce attenuated total reflectance (ATR, ZnSe IRE) with automatic purging of the optical path.
  • The Harrick Auto-Seagull automated variable angle IRRAS (angle specular reflectance in the range of 5 to 85 o). The Seagull can also be used for diffuse reflectance FTIR spectroscopy (DRIFTS) and variable angle attenuated total reflectance (ATR) for depth profiling. The Seagull is equipped with a KRS-5 rotatable polarizer and DRIFTS sample cup, but is not currently configured for ATR spectroscopy.
