Introduction:

The infrared spectrometer in our laboratory is Nicolet iS50 FT-IR produced by Thermo Fisher, which is one of the most advanced infrared spectrometers in Thermo Fisher. The instrument has the characteristics of fast scanning speed, high resolution and stable repeatability, and can be widely used in the fields of dyeing and weaving industry, environmental science, biology, material science, polymer chemistry, catalysis, coal structure research, petroleum industry, biomedicine, biochemistry, pharmacy, basic research of inorganic and coordination chemistry, semiconductor materials, daily chemical industry and other research fields.

Parameters:

• Infrared configuration spectrum range: 4000-50cm-1;
• Spectral resolution: better than 0.09cm-1;
• Wavenumber accuracy: 0.005 cm-1;
• The signal-to-noise ratio is better than 13000:1 (5 seconds);
• Interferometer: Maxon interferometer, with automatic adjustment of 3D laser control and dynamic alignment control function of more than 100000 high-speed scans per second
• Detectors: mid-infrared DLaTGS detector, enhanced DTGS detector and liquid nitrogen cooled MCT-A detector
