Introduction Many diseases involve the misfolding and aggregation of naturally occurring proteins in the body. These aggregates disrupt cellular function through a number of different mecha...
The utility model relates to a multi-component gas monitoring device based on an FTIR (Fourier Transform Infrared Spectroscopy) principle. The device comprises a power management module, an FTIR infrared sampling device, a data acquiring, processing and analyzing module and a real-time controlling ...
FTIR-PAS measurements were made using a PAC 300 photoacoustic detector accessory (MTEC Photoacoustics Inc., USA) for direct photoacoustic detection of optical absorption spectra of solids and semisolids with IR Fourier spectrometers. The working principle of the detector is based on a single-dimensiona...

Principle of IR Spectroscopy IR spectroscopy uses thermal radiation, which is invisible to the human eye, and interacts with matter by triggering lattice or molecular based vibrations. Each type of diamond has characteristic wavelength-regions where these vibrations occur. ...
The literature on SYPRO™ Ruby metal-chelate stain was re-evaluated and the effect of its application on proteinaceous media typically found in cultural heritage samples was assessed using the combination with optical microscopy (OM) and μ-FTIR spectroscopy. It is still common practice among ...
