Fluorimetry | Principle, Instrumentation and Applications

Fluorescence spectroscopy

Fluorimetry is a type of spectroscopy which measures the emitted radiation from a substance. This radiation is one which is emitted by the substance when the electrons transit from excited state to ground state. The principle of fluorescence spectroscopy: In UV-Visible spectroscopy, the excitation wavelength is measured. But, here the emission wavelength is measured. When […]

Azeotropic Distillation | With Two Examples and Applications

Azeotropic Distillation

You might have gone through different types of distillation techniques. Of them azeotropic distillation is quite interesting one. This method is used to separate azeotropic solutions. As per Wikipedia, an azeotrope is a mixture which cannot be separated by simple distillation. In general, most liquid mixtures can be separated by fractional distillation (FD). During the […]
