  • Solid-state automatic injection control device
    Patent number: 4517473
    Abstract: In order to control the auto-sampler in a device such as a gas chromatograph in which data is sampled by an analog-to-digital converter, the converter providing outputs indicative of its status and having one state when the converter is enabled, another state when the converter is disabled and pulsing between said states when the converter is acquiring data, an automatic injection control device is provided which: counts the sampling pulses from the converter to insure that a full conversion cycle has been completed and sets a first signal to so indicate; through a retriggerable, one-shot multivibrator insures that the last of the sampling pulses is completed and provides a second signal accordingly; and adds these two signals with the status signal indicating that the converter is in a condition to receive data to provide a trigger signal for use by the auto-sampler.Further, a method for generating triggering signals to initiate such event is presented.
