Abstract
A sample valve is a common GC injection device for continuous monitoring of organic compounds in air. We have reported the use of a microtrap in on-line analysis applications. These devices not only make automatic injections, but also serve as a sample preconcentrator. In this paper, the characteristics of microtrap-based injection systems in continuous on-line monitoring is presented. Air emissions from a pilot plant scale catalytic incinerator were monitored to demonstrate the applicability of the microtrap.
