Investigation of Ozone Concentration Measurement by Visible Photo Absorption Method

Investigation of the effect of inlet radius on the response time of a transmission type ozone sensor

“…The effect of inlet radius is discernible at all velocities considered; however its effect is more pronounced at lower flow rates. This is also justified by the authors of [14,25]; inlet radius is inversely proportional to the speed of response.…”

“…Length of Gas Cell (L) Gas Oulet Gas Inlet Fig.1: Transmission type gas cell The sensitivity, lower detection limit and the resolution of an absorption spectroscopic ozone sensor are proportional to its optical path length and thus longer gas cells yields better operations in terms of sensitivity, resolution and lower detection limits [10][11][12]; this however results in unsatisfactory sensing speed [13,14]. In this study, we investigate the effect of the inlet diameter of a transmission type optical gas sensor on the sensing speed of an optical sensor.…”

Highly efficient quenching of tris(2,2′-bipyridyl)ruthenium(ii) electrochemiluminescence by ozone using formaldehyde, methylglyoxal, and glyoxalate as co-reactants and its application to ozone sensing

“…[1][2][3][4] Ozone can dissolve in water and is an oxidant whose strength is nearly equal to that of fluorine. [1][2][3][4] Ozone can dissolve in water and is an oxidant whose strength is nearly equal to that of fluorine.…”

“…However, ozone is harmful to human health. [17][18][19][20] Ru(bpy) 3 2+ is one of most popular ECL reagents in aqueous solutions. [7][8][9][10][11] The indigo carmine (IDS) colorimetric method is usually interfered by other oxidants.…”

“…Recently, among various reactive oxygen species (ROS), ozone has been placed in the spotlight. [1][2][3][4] Ozone can dissolve in water and is an oxidant whose strength is nearly equal to that of fluorine. Therefore, ozone has been used in many fields involving medical tools, water treatment and food processing.…”
