New optical sensors for trace amounts of oxygen are based on platinum(II) and palladium(II) complexes of 5,10,15,20-meso-tetrakis-(2,3,4,5,6-pentafluorphenyl)-porphyrin covalently attached to the surface of amino-modified silica-gel particles. The dye-doped silica-gel particles are dispersed in silicone rubber. An optical dissolved oxygen sensor would make a better choice in these environments, as these sensors are not susceptible to interference by H 2 S. One advantage of galvanic DO sensors over optical DO sensors is that galvanic DO sensors have a faster response time.
