Abstract: Apparatus and process provide qualitative and quantitative analysis of sample constituent(s) in a fluid, relatively free from qualitative ambiguities and quantitative zero displacements due to slowly changing contamination in the measurement stream. Slowly changing zero displacement in the stream is cancelled out by the taking of continuous measurements at two points along the stream and continuously manipulating the two measurements as by subtraction.
