ABSTRACT:
An automatic fluid injector, useful for the injection of preselected small, accurately measured quantities of fluid specimens into, e.g., an analytical instrument, particularly a purge and trap analyzer. The injector includes generally a syringe, or syringe assembly, inclusive of a barrel into which a fluid specimen can be loaded, a plunger for the displacement of the fluid specimen from said barrel via the dispensing end thereof into the analyzer, and a probe integral therewith for the pick up of the fluid specimen for filling the barrel of the syringe. The combination further includes a magazine for transporting one or more fluid specimen-containing septum sealed vials for pick up of a fluid specimen therefrom by the probe portion of the syringe assembly for delivery to the barrel of the syringe. It thus relates to improvements in a fluid injection apparatus, especially to the combination of a syringe and injector feed assembly, and further combination including a tubular valve assembly which provide a mechanism for delivery of a fluid specimen to an analytical instrument, and purge mechanism.
