Abstract: A needle mount, or assembly for installation of a tubular needle on the forward end of an essentially otherwise conventional syringe. The syringe includes the conventional barrel, reciprocable plunger mounted from the rearward end and within the bore of the barrel, and tubular needle mounted on the forward end of the barrel. The bore at the forward end of the barrel is provided with a conical entry feature, and a hub with a central opening which can be aligned upon the conical entry is mounted on the forward end of the barrel.

Abstract: A new and improved magazine for use in automatic fluid injectors, and novel fluid injector for use in accurately measuring and injecting preselected quantitites of fluid specimens, or samples, into various media, e.g., a receptacle or septum inlet of a modern analytical instrument. In its preferred aspects, the invention is comprised of a new and novel magazine-injector combination.

Abstract: An apparatus for sampling and injecting measured liquid samples into the septum inlet of an analytical instrument or the like.

Abstract: An automatic fluid injector for accurately injecting preselected quantities of fluid specimens into an inlet of analytical instrument. The overall combination includes (a) the fluid injector sub-assembly, (b) an injector feed assembly for automatically continuously purging, cleaning and filling the barrel of said fluid injector sub-assembly and (c) a magazine, or feed tray, for transporting one or a plurality of vials of fluid specimens to the injector feed assembly for pick-up of the fluid specimen, and delivery to the barrel of said fluid injector sub-assembly. A feature of the invention is that fluid specimen can be passed from the extreme rearward end of the barrel of the fluid injector sub-assembly, entirely through the barrel and needle to purge, clean and remove contaminants as from previous specimens.

Abstract: An adapter unit, or apparatus for the receipt and containment of a fluid specimen sample under sub-atmospheric or supra-atmospheric pressure. The device is useful in facilitating the transfer of the fluid specimen to a fluid injector device, or needle syringe. In one form, the device is comprised of a valved, closed container the wall of which is fitted with oppositely disposed tubular seals within which is contained a reciprocable plunger. In another form, the device is constituted as an adapter unit which can be adjoined with a valved container for taking a sample therefrom, and subsequently separated therefrom, as desired. In either form, a yoke-like member or C-shaped frame is provided as an overall and necessary part of the combination. One end of the C-shaped frame is secured to a side of the reciprocable plunger, and the other end thereof is provided with a guide or holder.

Abstract: Am improved automatic fluid injector, or syringe, for accurately measuring and injecting quantities of fluid specimens, or samples, into various media, e.g., a receptacle or inlet of a modern analytical instrument, which includes the general combination of (a) an injector, or syringe assembly, inclusive of a needle syringe per se, (b) an injector feed assembly for automatically continuously purging, cleaning and filling the said syringe, and (c) a magazine, or feed tray, for transporting fluid specimen containing vials to the injector feed assembly for pick-up of the fluid specimen, and delivery to the syringe of the syringe assembly.
