| Abstract: | The simplified sampling method is a handy, cheap and convenient device without drive and with little restriction on the environment. It is suitable for the environmental investigation. The nitrogen oxide in the atmosphere can be collected by the principle of the molecule diffusion and then measured by use of the spectrophotometer. It possesses a high accuracy. |
