ABSTRACT

Two types of inductively coupled plasma with optical spectroscopic detection (ICP-OES), using air and argon as a plasma gas, have been compared for on-line monitoring of elemental pollutants in gases. The performance, advantages and disadvantages of these two systems are discussed. In the air plasma system, the gas to be analysed is used directly as the plasma gas; in the case of the argon plasma system, the gas to be monitored is injected at a low flow rate (0.5 l/min) into the plasma. These two methods can be used in stack gas control as well as in workshop air control. Limits of detection are in the range 1 to 10 μg/m−3 (1 to 10 ppb). The response time, for both techniques, is lower than one minute.
