ABSTRACT:
An automated fluid injector which includes, in combination, (A) a syringe, (B) an injector feed assembly for introducing a fluid specimen into the syringe, (C) a magazine for transporting fluid specimens for pick up by the injector feed assembly, and (D) an automatic drop counter. The automatic drop counter counts drops of a fluid specimen overflowed from the barrel, and is responsive to a preselected drop count to cut off the flow of fluid specimen transported from a vial by the probe sub-assembly, and trap a calibrated amount of the fluid specimen for injection. The automatic drop counter can also be used as a safety mechanism to shut down the operation of the instrument when no flow occurs over a preselected interval of time. By virtue of this combination, a wide range of highly volatile and highly viscous fluid specimens can be handled.
