Diffusion Coefficients in Aqueous Solutions of Potassium Chloride at High and Low Concentrations
Mutual differential isothermal diffusion coefficients of electrolytes in aqueous solutions have been measured in our laboratory using an open-ended capillary cell [112], Fig 1, developed some years ago. Diffusion may be followed by measuring the ratio of electrical resistances of the electrolyte solution in both capillaries as time proceeds, using an alternating current transformer bridge and a...
متن کاملPrecision measurement of ternary diffusion coefficients and implications for protein crystal growth: lysozyme chloride in aqueous ammonium chloride at 258C
Isothermal ternary diffusion coefficients for the system lysozyme chloride (1)+NH4Cl (2)+H2O at 258C and pH 4.5 have been measured interferometrically for five mean NH4Cl concentrations, C2 1⁄4 0:25, 0.5, 0.9, 1.2 and 1.5M, with C1 1⁄4 0:6mM. The main-term diffusion coefficient ðD11Þv varies slowly with C2. The main-term ðD22Þv increases with increasing NH4Cl concentration, as does the binary D...

15 صفحه اولMeasurements of Multicomponent Diffusion Coefficients for Lysozyme Chloride in Water and Aqueous Na2SO4
This paper presents a diffusion experimental study for ternary lysozymeNa2SO4-water system, from moderate precipitant concentrations into the supersaturated region and provides a complete set of four diffusion coefficients. These data are important in order to provide accurate models of protein diffusion with applications in growth of protein crystals for X-ray diffraction studies. All three-co...
متن کاملPrecision Measurements of Binary and Multicomponent Diffusion Coefficients in Protein Solutions Relevant to Crystal Growth: Lysozyme Chloride in Water and Aqueous NaCl at pH 4.5 and 25 °C⊥
Accurate models of protein diffusion are important in a number of applications, including liquidliquid phase separation and growth of protein crystals for X-ray diffraction studies. In concentrated multicomponent protein systems, significant deviations from pseudobinary behavior can be expected. Rayleigh interferometry is used to measure the four elements (Dij)v of the ternary diffusion coeffic...
