User Guides and Standard Operation Procedure are available for internal use.

High Resolution FT IR Specification and capabilities:

The high resolution (0.1cm-1) infrared spectrometer is equipped with a computerized dual quartz-halogen, near-IR/visible source and an Ever-Glo mid-IR source. Two beam splitters (KBr and CaF2) and two detectors (MCTA-A and DTGS-KBr) are available. The following table lists the spectral ranges of compatible beam splitter-detector combinations:

The unit is completely controlled through the OMNIC spectroscopy software and complemented with basic spectral library search and the TQ Analyst software.

There is also available the Gemini accessory that combines two sampling technologies in one device – Horizontal Attenuated Total Reflectance (HATR) and Diffuse Reflectance. HATR is a popular sampling technique for infrared analysis of many kinds of materials, especially strong IR absorbents with minimum sample preparation. Diffuse Refractance spectroscopy is a powerful technique for infrared analysis of fine particles and powders in concentrations that range from parts per thousand to neat. Powder samples can be measured ”as is” or mixed with a diffusely scattering matrix such as potassium bromide.

Thermo Nicolet FT-Raman Specification and Capabilities:

The Module is ideal for those who wish to exploit complementary data from both FT-Raman and FT-IR experiments on a single integrated system. Raman spectroscopy is based on the Raman Effect, which is the inelastic scattering of photons by molecules. Infrared (IR) and Raman spectroscopy both measure the vibrational energies of molecules but rely on different selection rules. The FT-Raman technique is ideal for a wide range of sample types. No sample preparation is normally required. FT-Raman allows collection of vibrational spectra of aqueous solutions without strong interference from water content, and FT-Raman allows non-destructive sampling through thin plastic bags, blister packs or glass bottles without the need to remove or have contact with the samples within the container. Fully integrated OMNIC software is used for complete range of data collection and manipulation of FT-Raman spectra.

The Raman module employs a Nd:YAG laser source at 1064 nm. In addition, two beam splitters KBr and CaF2, and InGaAs detector for Raman spectra.

For the FT-Raman module we have available the FT-Raman View Stage that provides both micro and macro sampling capabilities in a single compact accessory. The motorized x-y-z manipulator is fully controlled from the OMNIC spectroscopy software and the µView software allows selecting the analysis point by clicking on the video image. The View Stage is also supported by the Atlµs mapping software package, allowing automated collection of line and area maps in addition to the sampling of multiple, user-specified points on the sample.
