The phenomenon is widely used for elemental analysis How does XRF work When high energy photons xrays or gammarays are absorbed by atoms inner shell electrons are ejected from the atom becoming photoelectrons This leaves the atom in an excited state Pcr. 1. Limitations of End-Point PCR. Poor Precision. Low sensitivity. Low resolution. Non - Automated. Size-based discrimination only. Results are not expressed as numbers. Ethidium. bromide for staining is not very quantitative. 1. Dr. Nikhat Siddiqi. Principles.

It is a phenomenon of emission of radiation when the molecules are exited by radiation at certain wavelength.. FLUORIMETRY:-.
