    Absolute determination of electrolytic conductivity for primary standard KCl solutions from 0 to 50°C (1991)
    Springer
    Journal of solution chemistry 20 (1991), S. 391-401 
    Details
    ISSN: 1572-8927
    Keywords: Cell constant ; conductance ; demal ; electrolytic conductivity ; potassium chloride ; primary standards ; resistance ; specific conductance

    Topics: Chemistry and Pharmacology
    Notes: Abstract An absolute determination of aqueous electrolytic conductivity has been made for primary standards 0.01D and 0.1D (demal) potassium chloride solutions over the temperature range of 0 to 50°C in 5 degree intervals. A cell with a removable center section of accurately known length and area was used for the measurements. Values were adjusted to be in conformity with the ITS-90 temperature scale. The overall uncertainty over the entire temperature range is estimated to be 0.03%. Values at 25°C for 0.01D and 0.1D KCl solutions are 0.0014086 and 0.012852 S-cm−1, respectively.

    Determination of the absolute specific conductance of primary standard KCl solutions (1989)
    Springer
    Journal of solution chemistry 18 (1989), S. 515-528 
    Details
    ISSN: 1572-8927
    Keywords: Absolute standard ; conductivity cell ; demal ; electrolyte ; molality ; potassium chloride ; primary standard ; specific conductance
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A determination of the absolute specific conductance of KCl solutions is demonstrated. The measurement is based on the conductance cell with a well defined geometry, having a difference in the removable center tube of accurately measured dimensions. The specific conductance of the solution is obtained from the measured resistances of the cell with and without the center tube and the measured l/A ratio of the center tube. Specific conductances obtained using the cell agree with the previously accepted standards for 0.1 demal and 0.01 demal solutions within 0.02%. Results are also presented for solutions based on molality. The temperature control, bridge, and detector technology used to obtain results of this accuracy are described.
