PEAK DETECTOR AND AMPLIFIER CIRCUIT

摘要

An output circuit is provided for use with a chromatographic analyzer. The analyzer output is amplified and passed through an attenuation network to an integrator. The output signal from the integrator is applied selectively through an amplifier to the input of the first amplifier to provide an automatic zero circuit. Additional differentiating, peak reading and storage circuits are selectively connected to the output of the integrator.
