Abstract: An improved automatic fluid injector is described which includes generally (A) a syringe, or syringe assembly, inclusive of a barrel of relatively large diameter into which a fluid specimen can be loaded, and fluid specimen displaced from the barrel into the inlet of an analytical instrument, (B) an injector feed assembly for the pick up and of a fluid specimen for delivery to the barrel of the syringe, and (C) a magazine for transporting fluid specimen-containing vials for pick up by the injector feed assembly. The combination is one wherein the syringe assembly is integral with a carriage upon which it is mounted, the carriage providing a mechanism for loading a fluid specimen delivered from a vial via the injector feed assembly into the large diameter barrel without the formation of bubbles, or foam.
