System response analysis was performed on a chemiluminescence ammonia analyzer, a pulsed florescence hydrogen sulfide analyzer, and tubing used with flux chamber measurement. System responses were measured and evaluated using transfer functions. System responses must be taken into account so that data collected is not skewed up or down, causing measurements to be in error. By taking instrument response into account, an estimate of the true value may be obtained. This paper discusses an application of system response analysis to gaseous emission measurement equipment. The system responses for the analyzers were found to be first order with delay and dependent on the averaging time and gas input. The tubing response was found to be a first order response with delay.
