The principles of two existing methods of calibration based on flow injection methodology are outlined and the mathematical basis of a method based on peak width is presented. On the basis of the single well stirred tank model, it is shown that peak width at any concentration is proportional to logarithm of a function of concentration. The relationship is verified experimentally over the range 1–1000 p.p.m. of magnesium. The advantages and limitations of the method are discussed.
