Overview

The working principle of the circular dichroism fluorescence spectrometer CPL is to place the sample in an optical system and measure the signal within the wavelength range through components such as a rotating polarizer, fluorescence detector, and CD optical enhancer. It can measure in the ultraviolet to visible light range and generate CD and fluorescence spectra to analyze molecular structure and chemical environment.

Product Details

The circular dichroism fluorescence spectrometer CPL is an optical technique used to measure the absorption and fluorescence emission of molecules at different wavelengths. It can provide information about molecular structure, conformation, and chemical environment.

Circular dichroism (CD) refers to the phenomenon of optical rotation caused by differences in the absorption rate of light due to rotation in different directions when light passes through chiral molecules. CD spectra can provide important information about the stereochemical structure of molecules, such as the helical portion, amino acid conformation, etc. The intensity of CD spectrum is directly proportional to the content of chemical substances in the sample.

Fluorescence is the light radiation emitted by molecules due to electronic transitions when they are excited by energy. Fluorescence spectrometer can be used to measure the fluorescence emission intensity of samples at different wavelengths. Fluorescence spectroscopy can also provide information about molecular structure and environment.

The circular dichroism fluorescence spectrometer combines CD and fluorescence measurement techniques. It can simultaneously measure the CD and fluorescence signals of the sample, providing more comprehensive structural and chemical environmental information. Due to the influence of sample chirality, molecular structure, and environment on both CD and fluorescence signals, circular dichroism fluorescence spectrometer can be used to study the structure and function of many biomolecules such as proteins, nucleic acids, etc.
