Abstract
—A method is described for improving the transient gas concentration measurement in a relatively fast-developing fire or in any changing environment with a characteristic transient time that is comparable to the response time of the sampling system (including analyzer). Under such conditions, the measurements can be significantly altered in both time and magnitude and, hence, be of limited usefulness. The method utilizes the result of a simple laboratory test—the response of the measuring system to a step input—to determine the sampled concentration history from the analyzer record.
