High-Performance LSPEC 5030 Fourier Transform Infrared Spectrometer from China Suppliers & Factory

In its working principle, the instrument first emits stable infrared light from the light source. This beam enters the Michelson interferometer, where the periodic movement of the moving mirror generates interference light containing information across all wavelengths. When this interference light passes through the analyte placed in the sample cell, the sample molecules selectively absorb infrared energy at specific frequencies, thus allowing the interference light to carry information about the sample's molecular structure. Subsequently, the detector converts the interference light signal carrying sample information into an electrical signal, which is then sampled at high speed by the computer. Finally, using a Fast Fourier Transform algorithm, the time-domain interferogram is converted into a frequency-domain spectrum, yielding the sample's infrared absorption spectrum with absorbance or transmittance as the ordinate and wavenumber or wavelength as the abscissa.

Based on its superior qualitative analysis and quantitative detection capabilities, the LSPEC 5030 plays a crucial role in numerous scientific research and industrial fields.
