Kostov Y., Harms P., Pilato R.S, Rao G. (2000) Ratiometric oxygen sensing: detection of dual-emission ratio through a single emission filter. The Analyst, 125, 1175-1178.

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.
