An on-line instrument for the measurement of atmospheric NO(2) based on chemiluminescence reaction of Luminal with NO(2) was developed, optimized and characterized. The instrument is composed of a gas-liquid interface mini-reactor, gas and liquid transportation system, chemiluminescence detection system and data acquisition system. The linear range for NO, measurement is 5.0 x 10(11) - 8.0 x 10(-8)(V/V, volume ratio, same hereinafter), peak response time <1 s, time resolution is 1 s, and detection limit is 5.0 x 10(-11). The instrument is characterized by simple structure, small size and low cost.
