摘要： A system for monitoring the viability of an electrochemical cell measures the impedance of the cell over a wide range of impedances and with diminished phase shift over prior methods so that a more nearly accurate assessment of the impedance can be made. The system is particularly useful for four electrode systems, but is not so limited. It may advantageously be incorporated in the cell itself to further minimize cabling artifacts.

摘要： A measurement/calibration cell for potentiometrically measuring ion concentration in a fluid interposes a barrier between measuring and reference electrodes and positions the measuring electrode at a sufficiently higher gravimetric potential above the reference electrode that seepage of electrolyte from the latter to the former is effectively precluded. A controller associated with the cell displays instructions and other desired information on a scrolling display such that a substantial amount of information can be presented in a relatively small display window.

摘要： A modular potentiometric sensor includes a housing having measuring and reference half-cells, a temperature sensor, and solution ground combination assembly. An electrical conductor of the combination assembly extends through the housing, while remaining electrically isolated from the housing and half-cells, terminating at an electrically and thermally conductive end cap. Seals at opposite ends of the housing permit portions of the half-cells and the combination assembly to extend therethrough. The seals, measuring half-cell, and the combination assembly define an electrolyte compartment for the reference half-cell. The end cap provides close thermal coupling to the test fluid while also serving as a test fluid ground that is electrically isolated from the electrolyte compartment. The housing, measuring half-cell, reference half-cell, and combination assembly are modular, with the measurement sensor configurable in a plurality of lengths by altering the length of the housing independently of the half-cells and combination assembly.

摘要： Apparatus for calibrating an ion analyzer comprises a calibration cell having defined therein a first volume for measuring an ion concentration of a sample when the instrument is operated in a monitoring and a second volume for measuring the ion concentration when the instrument is operated in a calibration mode. The first volume is included in, and forms part of, the second volume so that the matrix for the calibration measurement is essentially identical to that for the sample measurement. A double known-addition is used during the calibration mode to determine the calibration parameters.

摘要： A pH half-cell method and apparatus includes an electrode, a pH sensitive glass membrane and an electrolyte in electrolytic contact with the electrode and membrane. The membrane includes at least about 15 mole percent lithium, and the electrolyte includes a lithium salt as the predominant monovalent cation. The pH half-cell is used with a reference half-cell and meter to provide an electrochemical potential measurement sensor, optionally with both half-cells disposed within a single housing. The lithium salt electrolyte is also used in a method for storing, conditioning, preserving and/or rehabilitating a pH half-cell.
