Diffusion coefficients were determined for the chloroform-air
system at 50°C and for the methanol-air system at 55°C by the Arnold cell
technique. The effect of concentration was studied by varying the
concentration of the gas stream passing across the top of the Arnold
cell.
The chloroform-air system exhibited a strong...
An experimental technique employing a moveable Mach-Zender
interferometer for measuring composition profiles in the gas phase
of an Arnold diffusion cell has been developed. The experimental
apparatus included a specially built cell having a pair of glass sides to
allow continuous detection of the refractive index. With the integrated
apparatus,...
