A titration method utilizing an anion exchange column (8 mm i. d.×10 mm length ; TSK-Gel SCX 10 μm) and a low volume mixer has been developed for the determination of salt concentration of brines by flow injection system. Samples are pumped through the column and alkalinised. The alkalinised samples are mixed with a reagent (phenolphthalein) and sent to a detector. And the peak width is observed. This method gives wide dynamic range (0.001〜0.4 M) with low sample volume (20 μl). Precision of the method is better than 1.5% R. S. D. (n=10) at the 0.01 M level for sodium chloride and the sampling rate is 120 samples/h. This method was successfully applied to the analysis of isotonic saline solutions.
