Abstract
A carrierless method is described for the analysis of a fluid sample for determination of the presence of a chemical species in the sample or for the determination of a physical characteristic of the sample. A portion of sample is drawn into a holding coil, followed by drawing one or more reagents (if desired) into the holding coil, then moving the sample and reagent (or reagents) through the reaction coil to a detector (e.g., calorimeter, potentiometer, ion selective electrode, fluorimetric detector, photometric detector, etc.). No separate carrier fluid is used in this method.
