What is FTIR Bruker?
What is FTIR Bruker?
What is FT-IR Spectroscopy? Each chemical substance has its own infrared signature, just like a finger print. Therefore, IR spectroscopy is a widely used analytical technique for the qualitative and quantitative analysis of various materials.
What is the difference between NIR and FTIR?
FTIR uses mid-infrared wavelengths of light (MIR), which are those between 20 and 2.5 µm wavelength. NIR uses near-infrared wavelengths of light (hence the NIR name) which are those of 2.5 to 0.7 µm wavelength.
How does FT NIR spectroscopy work?
Principle and Advantages of FT-NIR Spectroscopy When a sample is irradiated with NIR light, the absorbs the light and the matching molecular vibrations are activated. The outcome is a NIR spectrum containing absorption bands of varying molecular groups (predominantly N-H, C-H, and O-H bonds) at typical wavelengths.
Who is Bruker?
Bruker Corporation is an American manufacturer of scientific instruments for molecular and materials research, as well as for industrial and applied analysis.
What is interferogram in FTIR?
The Interferogram Interferogram is the name of the signal format acquired by an FT-IR spectrometer. It is usually significantly more complex than a single sinusoid, which would be expected if only a single wavelength of light was present.
What is NIR sensor?
NIR-based sensing provides machines with information about objects in the physical environment. When NIR light is emitted and reflected off of an object, an NIR sensor receives the reflected light or light pattern to gauge the distance, size, location, and identifying features of objects in the three-dimensional world.
What does FT NIR mean?
Fourier transform near-infrared spectroscopy
Fourier transform near-infrared spectroscopy (FT-NIR) is a non-destructive chemical analysis technology that provides a means to identify and analyze various materials.
What are NIR wavelengths?
Near Infrared (NIR) is a subset of the infrared band of the electromagnetic spectrum, covering the wavelengths ranging from 0.7 to 1.4 microns. This wavelength is just outside the range of what humans can see and can sometimes offers clearer details than what is achievable with visible light imaging.
What does NIR stand for?
NIR stands for Near Infrared Reflectance. NIR spectroscopy is the study of the interaction between a sample (e.g. cereals, seeds, oils, finished products) and infrared light that has been dispersed into individual wavelengths, usually by a prism.
Is Bruker German company?
History. The company was founded on September 7, 1960, in Karlsruhe, Germany as Bruker-Physik AG by five people, one of them being Günther Laukien, who was a professor at the University of Karlsruhe at the time.
