本文叙述了实验室中发展起来的自动大气臭氧分析仪。它不要人照顾就可以连续测数周以上。该仪器使用的原理是被臭氧从卤化物的磷酸盐缓冲溶液中释放出卤素并用原电池法测定卤素的浓度。采用了二个阴极和一个阳极的原电池示差测量技术;测定仪的本底和干扰电流是非常低和稳定的。干扰电流相当于约0·6μg/m~3的臭氧,而数星期周期的非累积漂 This article describes the automatic atmospheric ozone analyzer developed in the laboratory. It does not take care of people can be measured continuously for more than a week. The instrument uses the principle of ozone is released from the halogenated phosphate buffer solution of halogen and the use of galvanic cell method to determine the concentration of halogen. The primary cell differential measurement technique with two cathodes and one anode is used; the background of the analyzer and the disturbing current are very low and stable. Interference current equivalent to about 0.6μg / m ~ 3 of ozone, while the non-cumulative number of weeks cycle drift
