Oxygen compensation depth

Complete benchtop units are used routinely for monitoring dissolved oxygen in biological fluids and systems. Portable pressure- and temperature-compensated oxygen-electrode systems are available for monitoring oxygen levels in oceans, lakes, and rivers and in effluents and wastewaters at depths down to about 30 m. [Pg.75]

The determination of the depth of information in zeolite materials is difficult as the termination of the oxidic surface is not equal to that of a bulk crystallographic unit cell. A film of strongly bovmd adsorbates (mostly water) and possible contamination from synthesis, catalytic appUcation or ion exchange procedures (salts) will cover the zeolite surface and compensate for the significant polarity of the surface which is an unavoidable consequence of the termination of the crystal at its surface. In quantitative elemental analysis of zeolite materials, there will always be a significant excess of oxygen and carbon and often of alkali ions. This does not mean that these excess atoms are uniformly distributed... [Pg.470]
