| Abstract: | Gas-phase ozone was continuously measured by using the chemiluminescent reaction between indigo-5,5′-disulphonate and ozone. A detection limit of 0.4 ppb (v/v) was obtained using a reaction cell of 0.7 ml at a sampling rate of 15.0 ml min?1. The method was applied to the monitoring of ozone in the atmosphere. |
