Abstract: Apparatus, and process, for extracting organic fluids and solids specimens from weighed amounts of semi-solids and solids samples for collection, concentration and transfer to an analytic unit. The organic specimen is picked up by a probe assembly from a single compartment septum-sealed vial by heating and slurrying the sample, contacting with a gas; and then transferring the organic specimen with the gas to a collection device, e.g., a syringe or adsorbent trap. The specimen is then transported to an analytical instrument for analysis.

Abstract: Apparatus for processing solids and semi-solids specimens for the extraction therefrom of non-solids or fluid components for analysis. As a sub-assembly, the solids preparation and extraction device can be employed in combination with other sub-assemblies of an automated fluid injector which includes, or further includes, (B) a syringe, (C) an injector feed for introducing a fluid specimen into the syringe, and (D) a feed tray, magazine or carrousel for transporting fluid-specimen containing bottles, or vials for pick up of fluid therefrom by the injector feed assembly for delivery to the syringe. The apparatus embodiment also includes compartmented bottles, or vials, transportable via said feed tray to the solids preparation and extraction sub-assembly, within which a weighed amount of a solids or semi-solids specimen can be placed, crushed and the non-solids components thereof extracted, and removed; and also the process for extracting said non-solids component.

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.

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.

Abstract: A capillary fluid injector, particularly an automated capillary fluid injector, for dispensing very small accurately measured quantities of a fluid into a medium. A capillary opening of adjustable volume is located on the dispensing end of the fluid injector assembly.

Abstract: An apparatus, viz. an automatic fluid injector, useful for the injection of very small, accurately measured quantities of fluid specimens into various media, e.g., the inlets of modern analytical instruments. The improved apparatus combination embodies an injector feed assembly wherein the probe sub-assembly comprises the combination of (i) an outer rigid tubular needle of relatively large inside diameter, and (ii) an inner flexible tubular needle, one terminal end of which is concentrically contained within said outer rigid tubular needle and of sufficiently small outside diameter to form an annulus between the external surface of said inner flexible tubular needle and the internal surface of said outer rigid tubular needle, while the opposite end of said inner flexible tubular needle is communicated with the barrel of said syringe. The outer rigid tubular needle protects the inner flexible needle on thrust of the probe sub-assembly through the septum of a fluid specimen-containing vial.

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.
