Abstract:

The invention concerns an automatic continuous-flow fluid analyzer of the type wherein a stream of fluid, segmented by air bubbles or other separating medium inert to the fluid to be analyzed, passes through a colorimeter flow cell. The bubble artifact is eliminated from the photoconductor signal while allowing the signal produced from the fluid segment to remain intact. This is accomplished by means of a signal comparator which operates as a digitally controlled differentiator, but could alternatively be a purely analog differentiator. The signal comparator through continual signal comparisons momentarily samples and stores a photoconductor output.
