ABSTRACT:
Apparatus and method for analyzing successive liquid samples and conserving reagent. The method includes flowing a stream of discrete samples along a conduit from a source, which conduit includes a portion for reacting the successive samples with a reagent and a portion for analyzing the reaction product. It further includes introducing the reagent into the conduit upstream of the reaction portion to form a sample-reagent mixture, identifying the successive samples at the source, and responsive to such identification discontinuing the introduction of the reagent into the conduit and substituting therefore a pilot fluid displacing the mixture at the same flow rate along the reacting and analysis portions of the conduit.
