Device : Shimadzu IRPrestige-21 FTIR-8400S

Infrared (IR) absorption spectroscopy is a type of vibrational spectroscopy; IR rays are absorbed by the vibrational movements of the molecule. In mathematical Fourier transform spectroscopy, the luminous intensity is taken as a function of time. Fast and high resolution spectra can be obtained without the need to scan each wavelength separately. With this method, molecular bond characterization is done; The functional groups in the structure of solid, liquid, gaseous or solution organic compounds, whether the two compounds are the same, the state of the bonds in the structure, the bonding sites and whether the structure is aromatic or aliphatic can be determined.

Perkin Elmer Lambda 25 UV-Vis Spectrophotometer

UV-VIS Spectroscopy ; It is used to identify unknown substances in solution and to determine the concentration of known substances. Ultraviolet (100-400nm) and visible light (400-700nm) (UV-VIS) absorption spectroscopy is the measurement of the attenuation of a beam of light after it has passed through a sample or is reflected from a sample surface. A decrease in the intensity of light indicates an increase in absorption. Many molecules absorb UV or Vis wavelengths, and different molecules absorb different wavelengths. An absorption spectrum consists of many absorption bands that show the structure of the molecule.

Fluorescence spectroscopy detects concentrations as low as one-trillionth (nano-level). Luminescence can be measured directly, small emission can be amplified many times with little noise. Selectivity for two selectable wavelengths (excitation and emission) and a multidimensional information can be obtained in fluorescence spectrometry scanning.

Emission of metal complex ions with fluorescence can be measured. Fluorometic analysis has numerous applications to organic and biochemical species. The most important applications of fluorometer are food products, medicine, clinical samples, cell biology, cellular toxicity/viability, molecular toxicity, protein folding/unfolding, receptor (simple experiments, DNS teaching, binding studies, and protein measurement), research (assay development, cell-based study), apoptosis studies, and analyzes of phagocytosis / oxidative processes.
