Abstract: 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.

Abstract: A temperature-sensing thermistor and a heating element are positioned in a region of temperature to be controlled. The thermistor is connected in a bridge circuit, the output of which charges a capacitor. The voltage on the capacitor controls the firing of a thyristor which passes current to the heating element. Means are provided for discharging the capacitor periodically.
