The subject matter of the public contract is the supply of a high-temperature (heated) FT-IR
cell for high temperature experiments with a temperature controller and other accessories.
technique was the first spectroscopic method used to identify functional groups within a molecule.
When subjected to the insidence of an infrared beam, each chemical bond vibrates at specific wavelengths, generating a FT-IR
Thus, vibrational spectroscopy techniques and especially Fourier-transform infrared (FT-IR
) and Raman are nondestructive and noninvasive valuable characterization methods to elucidate material compositions, molecular structural changes, and environmental effects on biological and engineering materials in a variety of applications of the aquaculture industry [9-16].
On the basis of FT-IR
analysis, calculi were divided into three groups: pure stones (n = 71), mixed stones (n = 68), and pure stones with components in trace (n = 11).
The pure cooking oils, their WFOs and the respective biodiesel samples were analyzed by Fourier Transform Infrared Spectroscopy (FT-IR
The formation of the HAP phase was tested by FT-IR
spectra of the above samples were obtained using a Thermo Scientific Nicolet iN10 FT-IR
microscope as previously (29-32).
spectra were recorded by 2000 PERKIN ELMER in KBr disk containing 1.21.7 mg of the sample and 100 mg KBr.
spectroscopy is the most appropriate technique for stones analysis and is becoming the gold standard for stone analysis [3, 5].
But, in some normal conditions, FT-IR
analysis cannot be such quickly and accurately used to obtain the exact results information.
The synthesized PSTM-3T was characterized by scanning electron microscopy with energy dispersive spectrometer (SEM/EDS) and frontier-transform infrared (FT-IR
