ABSTRACT:
The concentration of weak acid and weak base constituents, or their soluble salts, in liquids is determined by passing succeeding samples of constant volume to a separation zone wherein target constituents are volatilized by reagents, then volatilized analytes are stripped from the liquid matrix and carried to a detection zone at a constant flow rate, wherein signals proportional to the variations in individual target analyte concentrations between succeeding samples are generated.
