Abstract
A filter probe for sampling components of a stack gas which includes means for extracting a flow sample of the stack gas, means for inertial filtering of the flowing stack gas sample extracted by the extracting means, means for collecting the flowing stack gas sample after filtering by the filtering means, means for conditioning the filtered and collected stack gas sample based on predetermined criteria such as cooling and drying, and means for flowing the filtered and collected stack gas sample from the collecting means to the extracting means so that a constant flow of the filtered stack gas sample is presented to the conditioning means to permit essentially instantaneous analysis of the stack gas sample.
