Abstract

The determination of photographic processing solutions through buffer curve analysis was investigated to determine its advantages, limitations, and general usefulness. A microprocessor controlled titration system was set up to perform up to 16 unassisted titrations and record the data on a floppy disk system at a speed five times faster than the speed of manual titrations. The ingredients are not detectable by this analysis if their concentrations are much less than 1/10th the normality of the ingredient with the largest concentration that is detectable by this analysis. There is linearity between the concentration of a single ingredient solution and the volume of titrant required to reach the final endpoint, but this linearity fails when more than one ingredient is in the solution. This analysis is able to detect a significant number of ingredients used in photographic processing solutions. The analysis can be useful in analyzing competitors' products and photographic processor control.
