Ionic strength measurement
WebThe mobilities were detd. at 25.0° in a coated capillary with suppressed electroosmotic flow. The resulting fitting equation, valid under these conditions, is μ/μ0 = exp(-0.773zI). The difference between measured mobilities and mobilities calcd. from a tenfold higher or lower ionic strength, using this equation, is within 5% for all expts. Ionic strength is typically calculated as the product of a given ion's concentration, ci, and its charge, zi, summed over all ions in solution, divided by two (IUPAC Quantities, Units and Symbols in Physical Chemistry, 1993), and measured either as mass per unit volume (i.e., mg/L) or in moles (i.e., mmol/L).

The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a solution with dissolved ions is the ionic strength. Ionic strength can be molar (mol/L solution) or molal (mol/kg solvent) and to avoid confusion the units s… WebWith high ionic strength buffers, the choice of cocktails includes Ultima Gold XR, Optiphase Hi-Safe 3, LumaSafe Plus, Hionic-Fluor, or Pico-Fluor 40. Certain high ionic strength samples can be accommodated in other cocktails, however the capacity is usually very low (less than 0.5 mL). The only other method of overcoming the problem of low …
WebEffect of ionic strength on antigen-antibody reaction is particularly important in blood group serology. Here the reaction is significantly influenced by sodium and chloride ions. For example, in normal saline solution, Na+ and Cl− cluster around the complex and partially neutralize charges, potentially interfering with antibody binding to antigen.
