Analyte anions separated on a Hamilton PRP-1 reverse-phase column using Iron (II) 1, 10-phenanthroKne [Fe (phen) 32+] salts as mobile-phase additives can be detected indirectly because absorbance within the analyte band differs from the background absorbance provided by the Fe (phen) 32+ salt con-taining mobile phase. Three major factors cause Fe (phen) 32+ concentration to change within the analyte band. These are Ionic strength change within the band relative to the back-ground, the type of counteranlon (s)(anion selectivity) In the mobile phase, and the concentration (mass action) of the counteranlon (s) and analyte anlon (s) In the mobile phase. Depending on conditions, Fe (phen) 32+ concentration within the band can either Increase (positive analyte peaks) or de-crease (negative analyte peaks). Mobile-phase variables that directly or Indirectly affect ionic strength or counteranion conditions, and consequently Influence Indirect photometric detection and detection limits, are Fe (phen) 32+ concentration, solvent composition, type and concentration of counteranlon (s) provided by Fe (phen) 32+, buffer, and Ionic strength salts, pH, and amount of Injected analyte. Molar absorptivity of the metal complex used as the ion Interaction reagent also affects detection limits. Contingent on the absorption detector, the analyte anion, and optimization of the parameters, calibration provides a broad linear dynamic range and de-tection limits within the 1-10 ng range.
