“…The limit of detection (LOD) is 20 nM, which is comparable to the best LOD values of other reported ozone detection methods. 1,2,9,10,16,28,29 The method has nice reproducibility with a relative standard deviation (RSD, n = 7) of 3.2%. The selectivity of the proposed ECL inhibition detection of ozone was also investigated.…”

“…Employing IDS spectrophotometry, one fills an absorption tube with a porous glass plate containing ozone. The concentration of ozone is then measured with a spectrophotometer at 610 nm using a blue IDS solution [10,11]. The chemiluminescence method uses ozone and excess ethylene or nitric oxide (NO) in the reaction, and then a photomultiplier tube to measure the luminescence intensity of ozone [12,13].…”

Ozone is known as a "god-given purifying agent", and its quantitative detection is of great significance. A low-cost photoacoustic spectroscopy (PAS) which is based on absorption at the low-power blue diode emitting at 403.65 nm has been used for nitrogen oxide (NO2) concentration measurements. According to the formula of nitric oxide (NO) reaction and ozone (O3) production of NO2 and the differential detection method, a dual-channel PAS system for O3 detection is reported. The consistency of NO2 detection with the dual-channel photoacoustic spectroscopy system is good by contrast. The coefficient of determination R 2 can still reach 0.846. An intercomparison between the system and a cavity ring-down system (CRDS) was shown to verify the accuracy. The results showed a linear correction factor (R 2 ) of 0.943 in a slope of 0.862±0.002, with an offset of (0.773±0.128) ppb. In addition, the measurement of O3 using the dual-channel cavity photoacoustic spectroscopy technique was deployed. These observations indicate that O3 concentrations can be effectively observed with the dual-channel PAS instrument.

“…Gravimetric sensors based on a quartz crystal microbalance (QCM) coating with 1,4-polybutadiene have shown good performance for indoor O 3 applications [22]. The polybutadiene–QCM exhibits an irreversible reaction with O 3 with a detection limit below 10 ppb [23] and insignificant interference from NO 2 , formaldehyde, CO, and phenol.…”

Sensitive and selective personal exposure monitors are needed to assess ozone (O3) concentrations in the workplace atmosphere in real time for the analysis and prevention of health risks. Here, a cumulative gas sensor using visible spectroscopy for real-time O3 determination is described. The sensing chip is a mesoporous silica thin film deposited on transparent glass and impregnated with methylene blue (MB). The sensor is reproducible, stable for at least 50 days, sensitive to 10 ppb O3 (one-tenth of the occupational exposure limit value in France, Swiss, Canada, U.K., Japan, and the USA) with a measurement range tested up to 500 ppb, and insensitive to NO2 and to large variation in relative humidity. A model and its derivative as a function of time are proposed to convert in real time the sensor response to concentrations, and an excellent correlation was obtained between those data and reference O3 concentrations. This sensor is based on a relatively cheap sensing material and a robust detection system, and its analytical performance makes it suitable for monitoring real-time O3 concentrations in workplaces to promote a safer environment for workers.
