1. A batch injection analysis apparatus for measuring analyte sample concentration comprising:
- vessel means;
single batch electrolyte means confined within said vessel means;
means for serially introducing into said vessel means, for dilution in said single batch electrolyte means, multiple analyte samples to be analyzed, the volume of each said analyte sample having a proportional ratio to the volume of said single batch electrolyte means within the range of 1/20,000 to 1/50,000;
planar detection means in said vessel means for sensing said analyte samples to be analyzed; and
means for analyzing said analyte samples.

Abstract
Batch injection analysis comprises apparatus and method for injecting and transporting analytes toward a detector immersed in a confined, inert electrolyte. Passage of the analyte over the detector surface provides measurement of sample concentrations. Detectors normally comprise selective electrodes, such as biologically or chemically modified surfaces, ion-selective probes, optical or thermal devices, thus eliminating conduits, valves, and pumps.
