In this contribution, the results of the measurement of the production of ozone and nitrogen oxides in the air processed by a corona discharge or a spark discharge in a needle-to-plate non-thermal plasma reactor are presented. The results show that the corona discharge generated in the air produces O, and N,O. Their concentrations increased with the increasing residence time. Neither NO nor NO2 were produced in the corona discharge. However, the production of NO and NO2 was observed when the air was processed by the spark discharge. Contrary to the corona discharge, the spark did not produce ozone. The absence of the production of NO and NO2 in the positive corona discharge is in contradiction with many previous results.
