Sample accessories can be used with this spectrometer to enable analysis using the following method: no problems are caused by the fluctuation of a dry air purge supply.weak spectral features of some samples are not masked by moisture absorptions.Other advantages that the vacuum system offers include the following: A vacuum pump allows for evacuation of the optic bench to significantly reduce the infrared active atmospheric water and carbon dioxide absorptions. This is a high-end research grade FTIR instrument equipped to collect spectra over the NIR (15500 – 4000 cm -1), MIR (12000 – 850 cm -1) and FIR (680 – 50 cm -1) spectral ranges using an evacuated optics bench. There is also the option to have gas flow-through in the sample chamber. Linkam variable temperature stage – enables analysis of liquids or solids at temperatures ranging from –196° C to 600° C.Bioptech live cell incubator accessory - enables real-time analysis of changes in live cells under culture conditions.Grazing angle (GA) - directs infrared light across the sample surface at an incident angle of ~ 84° creating an increased path length of the sample provide high sensitivity and making it ideal for microanalysis of thin coatings on metallic substrates, even down to monolayer thickness.Attenuated total reflectance (ATR) - used for analysis of materials that are strong absorbers and can provide information about the surface properties of a material.In addition to standard transmission and reflection measurements, this system also has: Specialised objectives are available for attenuated total reflectance (ATR) and grazing angle (GA) experiments and a live cell incubator accessory enables real-time analysis of changes in live cells under culture conditions. the spatial x, y co-ordinates to obtain a visual distribution of one or more characteristic functional groups. 2D/3D false colour maps are generated by plotting the intensity/area/peak-ratio of a characteristic peak(s) vs. Mapping involves the collection of spectra from specific, user-defined regions of interest using points, lines or grids, while imaging is the simultaneous collection of spectra using a 64 x 64 FPA detector with each of the 4096 pixels in the array representing a spectrum. It is coupled to the Hyperion 3000 microscope which has an MCT (Mercury Cadmium Telluride) and FPA (Focal Plane Array) detector allowing collection of spectra in single point, mapping or imaging modes. The Bruker Tensor 27 spectrometer is equipped to collect spectra over the MIR spectral range (7000 - 600 cm -1).
