    • An improved ISE is provided for measuring the concentration of an electrolyte in a sample in a centrifuge-type analyzer utilizing a multichamber test pack. The reference cell and sensor cell of the ISE are each comprised of an electrode, fill solution, housing and membrane in a fully self-contained configuration. Each cell is of sufficiently small size to fit in the test pack. The electrode of each cell is provided with screw threads to allow each cell to be screwed directly into the test pack thereby securing the cell to the test pack and at the same time providing a convenient electrical contact to the readout electronics of the test pack. With the present design manipulation of the ISE sensor output voltage can be achieved by varying the known ion concentration of the fill solution. Also provided is a novel method of introducing a fill solution into the cell after all of the cell components are in place.
    • 提供了一种改进的ISE,用于在使用多室试验包的离心机型分析仪中测量样品中电解质的浓度。 ISE的参比单元和传感器单元各自由完全独立构型的电极,填充溶液,外壳和膜构成。 每个电池的尺寸都足够小以适应测试包。 每个电池的电极设有螺纹,以使每个电池可以直接拧入测试包中,从而将电池固定到测试包上,同时提供与测试包的读出电子装置的方便的电气接触。 通过改变已知的填充溶液离子浓度可以实现ISE传感器输出电压的目前设计操作。 还提供了在所有电池组件就位之后将填充溶液引入电池的新方法。

    • A miniaturized reference electrode includes a dielectric thermoplastic cup having a cavity to hold a reference liquid solution and having a sample contacting orifice at one end. A membrane comprising cellulose acetate and a solvent capable of exerting a solvent action on the sidewalls of the cup orifice is drop deposited in the orifice and cured in situ. The resulting membrane extends across the orifice and is interdigitatedly anchored to the orifice sidewalls. The reference electrode further includes an Ag/AgCl screw-in electrode machined from silver rod extending into and hermetically sealing the cup cavity. A reference liquid fill solution having a chloride ion and potassium ion concentration similar to that found in the samples to be tested and the storage soak solution is provided to minimize drift of reference potential. The miniature reference electrode is intended for use with a miniaturized ISE half cell in a test cartridge on a centrifugal clinical analyzer to determine electrolyte concentrations in fluid samples.
    • 小型化参考电极包括具有空腔的电介质热塑性杯,以保持参考液体溶液并且在一端具有样品接触口。 包含乙酸纤维素和能够在杯孔的侧壁上施加溶剂作用的溶剂的膜会沉积在孔中并原位固化。 所得到的膜延伸穿过孔并且被叉指地锚定到孔侧壁。 参考电极还包括由银棒加工的Ag / AgCl螺旋电极,其延伸到气囊密封杯腔。 提供具有类似于待测试样品中的氯离子和钾离子浓度的参考液体填充溶液和储存浸泡溶液以使参考电位的漂移最小化。 微型参比电极旨在用于离心式临床分析仪上的测试盒中的小型化ISE半电池,以确定流体样品中的电解质浓度。
