Abstract

The need for accurate measurements of trace gases in tropospheric air is well recognized. An instrumental system ideally suited for such measurements should have the following characteristics: 1. Universality; it should be applicable to a wide variety of gases. 2. Specificity; it should provide positive identification of the target gas. 3. Freedom of interferences from other constituents. 4. Rapid response of one minute or less, permitting real-time measurements. 5. High sensitivity of less than 1 ppbv.
