Dissolved Oxygen Saturation Concentration Description

Oxygen saturation - Wikipedia

Oxygen saturation (symbol SO 2) is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. The standard unit of oxygen saturation is percent

Effects of dissolved oxygen concentration on

The effects of the dissolved oxygen concentration (DO; from 0.1 to saturation with air) on Sp2/0‐derived mouse hybridomas were investigated using continuous culture. The steady‐state concentration of viable cells increased with decreasing DO until a critical dissolved oxygen concentration of 0.5% of air saturation was reached. The cell concentration declined at lower DO

The concentration of dissolved oxygen in water depends also on temperature, pressure, and concentrations of various ions [cf., Hutchinson (1957), Wetzel (1999)]. To be successful, a method for measuring dissolved oxygen must meet two requirements. First, owing to the small amount of substance to be determined (a few mg/l), it must be exact; second, it must be done with apparatus

Dissolved Oxygen - Environmental Measurement

Dissolved oxygen concentrations are constantly affected by diffusion and aeration, photosynthesis, respiration and decomposition. While water equilibrates toward air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³. As such, dissolved oxygen levels can range from less than 1 mg/L to more than 20 mg/L depending on how all of these

Normally dissolved oxygen from air in fresh water and sea water (salt water) at pressures ranging 1 - 4 bar abs are indicated in the diagrams and tables below.. Note! - in air with normal composition the oxygen partial pressure is 20% of the total pressure. This results in 20% oxygen dissolution from air compared to pure oxygen..

solubility - Two ways to calculate dissolved

To calculate the dissolved oxygen in water at saturation pressure at 25 °C, we do: $$ D_ce{O2} = K_mat{H} times M times p_mat{g} $$ $$ D_ce{O2}~[pu{g/L}]= 1.26times10^{-3}~[pu{mol/L/atm}] times 32~[pu{g/mol}] times 0.21~[pu{atm}] $$ I used $pu{1.26E-3 mol/L/atm}$ for the Henry's constant for $ce{O2}$ in water at 25C which is from Warneck and Williams (2012), which

Calculating Oxygen Percent Saturation - Nc

Oxygen percent saturation compares an observed oxygen concentration to the absolute solubility of oxygen at a particular water temperature. This index often takes into account barometric pressure and salinity effects at the measurement site, but usually ignores effects of water pressure at depths below a lake or stream surface. Solubility of gases increases by an amount equal to the surface

Increasing dissolved solids concentrations also decrease the solubility of oxygen. The saturation concentration of oxygen in deionized water at 1.0°C and standard air pressure is 14.2 parts per million (ppm); this is equivalent to about one drop from an eye-dropper in one gallon.
