1. In a reaction detection system for determining the reaction rate of a sample wherein said reaction is represented by an electrical input signal which can vary in accordance with said reaction during a predetermined time increment, the combination including;

  • input means for receiving said electrical input signal,first sampling means coupled to said input means and operative at predetermined first intervals to sample said electrical input signal and develop a first sampling signal during said sampling proportional to said electrical input signal and to hold said first sampling signal until the following sampling,second sampling means coupled to said first sampling means and operative at predetermined second intervals to sample said first sampling signal and develop a second sampling signal during said sampling proportional to said first sampling signal and to hold said sampling signal until the following sampling,summing circuit means coupled to said first and second sampling means and operative to develop an output signal representing the difference between said first and second sampling signals, anddisplay means coupled to said summing means and operative in response to said output signal to display an output proportional to said output signal.
