Abstract
An analyzer for measuring the ionic values of electrolytes in a sample solution having a fluid flow-through air segment detector (300) and a plurality of fluid flow-through ion selective electrodes (97,98) for measuring the ionic values of electrolytes and a fluid flow-through reference membrane assembly (96) connected in series. There is also a reference electrode (95). There is a reservoir (77) containing an internal filling solution. The reference membrane assembly and the reference electrode are located in the reservoir and exposed to the internal filling solution. A tubular fluid sampling probe (70) having a sampling port (63) aspirates air, sample and liquid reagents through the system. The probe cooperates with a slide valve (64) having a passageway (53) through which the probe reciprocates. The passageway contains a plurality of chamber ports (46, 47, 48) each of which is sealed from the other ports by the tube sampling probe when its sampling port is positioned within a chamber port, A reagent pouch having a plurality of chambers communicating with a separate chamber port in the slide valve (20, 21) contains liquid reagents and a wash solution. One chamber in the reagent p…
