Ratiometric oxygen sensing: detection of dual-emission ratio through a single emission filter.

Y Kostov1, P Harms, R S Pilato, G Rao.   

Abstract

A new method and device for the ratiometric measurement of oxygen concentration are presented. They are based on the use of a dual-emission oxygen-sensitive dye. The method allows the exclusion of the influence of emission overlap. The detection of the dual-emission ratio is performed using a single long-pass emission filter. The device described is simpler than the widely used lifetime instruments and could easily be a stand-alone low-cost instrument.
