Description
The present invention relates to a multi-emission spectral analysis method using a multi-band type color selection mirror and a multi-emission spectral analysis apparatus using the same.
Fluorescence refers to light generated when light is irradiated on a sample, when the energy state inside the sample transitions from a ground state to an excited state and returns to the ground state within a few nanoseconds within a short time. Phosphorescence is similar to fluorescence but when it returns to the ground state, it emits light in a delayed time rather than fluorescence because it passes through the triplet state, which is an intermediate energy level.
The emission spectrometer is a device used for analyzing the optical and photochemical properties of a sample by measuring fluorescence or phosphorescence generated from a sample irradiated with light by wavelength and clarifying the microstructure of the material. Such an emission spectrometer can be applied to various fields such as biotechnology and genetic engineering such as DNA structure analysis and DNA sequencing, environmental field such as analysis of the content of organic matters in water, analytical chemistry such as calculation of chemical reaction and quantum efficiency, Etc., as well as in the field of polymeric compound quantification, film coating, and the like.
