1. A method of determining the concentration or activity of a material present in a sample which is chemically reacted in batch comprising:

  • monitoring a property or characteristic of a component or product of said reaction related to concentration of a substance in said batch;

    generating a first electrical signal related to said concentration of said substance;

    differentiating said first signal to obtain an output signal proportional to the instantaneous time rate of change of concentration of said substance; and

    measuring said output signal to determine the concentration or activity of said material.
