Abstract
A detector having particular utility in a gas chromotograph uses a sensor to produce signals indicative of parameters of components of a gas. A signal whose level is related to a gas parameter is generated and sent to an amplifier. The output of the amplifier is stored and a signal related to the amplifier output signal is sent by means of a feedback loop to the input of the amplifier to compensate for losses in the amplification and storage processes.
