Abstract: Apparatus for measuring electrolyte concen­trations in fluid samples is provided. The apparatus includes an ion selective electrode having a plurality of ion selective detection sites. Each site has an affinity for a preselected electrolyte of interest and generates a potential having a magnitude related to the concentration of the corresponding electrolyte in the sample. A voltage to optical transducer circuit is provided to convert the voltage differentials to optical signals having intensity related to the concentration of the electrolytes in a first embodiment, a digital code related to the concentration of the electrolytes in a second embodiment, and an optical absorption or density value related to the concentration of the electrolytes in a third embodiment. The optical signals are suitable for detection by conventional optical detector apparatus of assay instruments and may be processed using conven­tional two point linear interpolation techniques to determine the concentrations of the preselected electrolytes.

Abstract: A bubble flushing aspirating and dispensing syringe having precision and volumetric accuracy, particularly for use in an automated, continuous and random access analytical system, is disclosed. The syringe comprises a piston (124) within a bore (128), the bore having seal means at a first end and a closed end (130) at a second end, wherein the piston forms an annulus (138) with the bore wall and seal means, and is capable of reciprocating therein. Fluid inlet (134) and fluid outlet (136) means are in communication with the annulus (138) and bore, the fluid inlet and fluid outlet means being located between the seal means and the bore closed end. A fluid source is in communication with the inlet means and a fluid conduit is in communication with the outlet means and an open-ended release tip. A drive means is connected to the piston for reciprocating the piston within the bore. As a result, fluid from the inlet, when connected to a fluid supply, flows through the annulus (138) around the sides of the piston and out through the fluid outlet to the open-ended tip, thereby creating a cross-flow pattern in the annulus (138) around the piston as it reciprocates in the bore to flush bubbles through the outlet.

Abstract: A bubble flushing aspirating and dispensing syringe having precision and volumetric accuracy, particularly for use in an automated, continuous and random access analytical system, is disclosed. The syringe comprises a piston (124) within a bore (128), the bore having seal means at a first end and a closed end (130) at a second end, wherein the piston forms an annulus (138) with the bore wall and seal means, and is capable of reciprocating therein. Fluid inlet (134) and fluid outlet (136) means are in communication with the annulus (138) and bore, the fluid inlet and fluid outlet means being located between the seal means and the bore closed end. A fluid source is in communication with the inlet means and a fluid conduit is in communication with the outlet means and an open-ended release tip. A drive means is connected to the piston for reciprocating the piston within the bore. As a result, fluid from the inlet, when connected to a fluid supply, flows through the annulus (138) around the sides of the piston and out through the fluid outlet to the open-ended tip, thereby creating a cross-flow pattern in the annulus (138) around the piston as it reciprocates in the bore to flush bubbles through the outlet.
