  • On Line Measurement of Oxygen: Review and New Developments

    Keywords Oxygen. Paramagnetic, Zirconia, Tunable Diode Lasers Abstract Oxygen is vitally important to the existence of animal life, not only for respiration, but also for the many aspects of the combustion reaction (power generation, vehicular movement, heating) and process control, safety and quality. Continuous measurement techniques are correspondingly ...

  • Effect of Dissolved Oxygen (and Bubbles) on the Measured Permittivity of Geotextiles

    Measurements are made of the permittivity in a heat set, nonwoven staple filament polypropylene as a function of the dissolved oxygen content (DOC) of the water. Vacuum deairing of the water to a DOC of 5 ppm or below insures that the measured permittivity will not be lowered by oxygen effects. Careful long-term measurements show that the measured permittivity is reduced very significantly if the ...

  • Measurement of Particle-Bound Reactive Oxygen Species in Rubidoux Aerosols

    The diurnal variations in the concentrations of reactive oxygen species (ROS) in various size fractions were determined for ambient particles in Rubidoux, CA. Sampling of particles was conducted at 3 h intervals using a cascade impactor. The collected particles were reacted with dichlorofluorescin (DCFH), a non-fluorescent probe that fluoresces when oxidized. The factors affecting the diurnal ...
