Verification of satellite ozone/temperature profile ...

2019-04-15· The ozone detector based on an electrochemical concentration cell (ECC) has been widely used (Komhyr et al., 1995). This is because the high quality of ozone data from soundings is better than that of satellite inversion data, which has promoted the development of satellite inversion technology. The microwave limb sounder (MLS) on the Aura satellite and atmospheric infrared sounder (AIRS) on ...

ISO 13964:1998(en), Air quality ? Determination of ozone ...

Ozone is a toxic gas and good laboratory practice should limit indoor ozone concentrations to less than 200 ?g/m 3 (volume fraction 1 × 10 7). Consult a reference text for more details on hazards and safety of ozone. Any excess should be vented into an activated charcoal scrubber (with negligible back-pressure) or outdoors well away from any sampling intake. 1 Scope. This International ...

US EPA Ozone Antimicrobial Efficacy

Ozone-laden air, nominally 500 ppm, flowing at several liters per minute through the exposure chamber, was diluted 1:1000 with clean air to allow detection by the TECO 49 analyzer. The ozone-containing air entered through a port at the bottom of the rear wall of the exposure chamber. Ozone/air vented from the exposure chamber from a port at the center of the chamber's back wall (and then ...

Wastewater Technology Fact Sheet: Ozone Disinfection

Ozone in gaseous form is explosive once it reaches a concentration of 240 g/m 3. Since most ozonation systems never exceed a gaseous ozone concentration of 50 to 200 g/m 3, this is generally not a problem. However, ozone in gaseous form will remain hazardous for a significant amount of time thus, extreme caution is needed when operating the ozone gas systems. It is important that the ozone ...
