Design and Operation of a Signal Comparator to Increase Efficiency of Continuous-Flow Analyzers

Abstract

Abstract Design features and operation of a signal comparator are described. The efficiency of continuous-flow analyzers is improved by allowing the bubbled stream to remain intact as it passes through the colorimeter flow cell. The signal comparator eliminates the bubble artifact from the photodetector signal while allowing the signal produced from the fluid segment to remain intact. The instrument is reliable, easy to use, and does not require any adjustments by a technician.
