Maintenance of a Developer by Continuous Replenishment
By a series of simple assumptions that do not appreciably depart from current practice, it is shown that it is possible to calculate readily the concentration of any ingredient present in a continuously replenished developer solution during use. The equations for the equilibria and rates of growth of the various substances are derived, and applied to a practical case. The benefits of chemical analyses for developer constituents both for maintenance of quality and for economy are pointed out. The analytical methods published by Lehmann and Tausch are outlined briefly.
