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.
