Apparatus and process provide qualitative and quantitative analysis of sample constituent(s) in a stream of fluid, relatively free from qualitative ambiguities and quantitative zero displacements due to slowly changing contamination in the measurement stream. Slowly changing zero displacement of a continuous measurement signal - caused by slowly changing contaminant concentrations in the stream - is cancelled out by deriving two continuous versions of the measurement signal, both being time-distorted, and continuously manipulating the two versions as by subtraction.
