Relative Quantum Yield of 2-Aminopyridine

Edinburgh Instruments Ltd.

Quantum yield is a photophysical parameter describing a sample's fluorescence efficiency. It can be measured optically via the absolute method and relative method. 2-Aminopyridine in sulfuric acid has been previously used as a QY reference standard in the UV-vis range but the 2AMP QY values are now decades old. Edinburgh Instruments presents a reinvestigation and revaluation of the quantum yield of 2AMP in 1M H2SO4, using quinine bisulphate in 1M H2SO4 as the reference standard with a Spectrofluorometer.
