Fourier Transform Infrared (FTIR) Spectrometer and Infrared Microscope
Bruker Vertex 70 Fourier Transform Infrared Spectrometer
This is a research-grade FTIR with resolution to 0.5 cm-1, equipped with:
- Temperature controlled transmittance cell system (Pike Falcon)
- Single-bounce Attenuated Total Reflectance (ATR) accessory typically used for solid samples (Bruker Platinum ATR)
- Multiple-bounce Attenuated Total Reflectance (ATR) accessory typically used for liquid samples. This unit has variable temperature capability and can also operate with a dialysis membrane in its flow cell to allow in-situ changes in solvent/buffer composition such as H2O/D2O exchange, pH changes, salt composition changes etc.
- Detectors: MCT (liquid nitrogen cooled) for sample compartment; RT-DLaTGS (room temperature) for sample compartment; Microscope has its own MCT detector.
Bruker Hyperion Infrared Microscope
This microscope makes images of a sample using visible light and then acquires infrared spectra from points in the sample, guided by the visible-light image. For visible light there is a video camera and the X/Y-stage is under computer control. Collection of infrared spectra from multiple points in an image can be automated with points selected individually using mouse clicks, along a line or in a rectangular array. (The Hyperion infrared microscope is coupled to the Vertex 70 spectrophotometer and relies on its infrared light source and interferometer.)
- Transmission and Reflection modes
- MCT Detector (liquid nitrogen cooled)
- Objectives: 15x, 36x and 4x (visible only; used for navigation), Attenuated-Total Reflectance (ATR), Grazing Incidence
