    I Colloid complex refractive index from UV-vis spec

    Hi everyone, I am wondering, can I use the damped wave approximation for light travelling through a medium along with Beers law to spectroscopically determine a colloid complex refractive index. Thanks! Absorbance = exp (- 2πkx/λ) = ecl

    2D electric field distribution in electrolyte solution

    Thanks Borek! We would apply the potential between the working and counter electrodes. The problem also needs to account for field screening due to the presence of the electric double layer. (Electric field distribution in vacuum is much more straightforward!) I would also make a few...

    Fluorescent Sample with Cuvette but not with Plate -- Why?

    Probably the sensitivity and different background noise of each instruments. Plate readers used in bio-assays are generally much less sensitive than traditional cuvette fluorometers. You could also get some background noise if your detector is not at a right angle from the light source.

    2D electric field distribution in electrolyte solution

    Hi there, How can I determine the electric field distribution from a planar electrode? The known parameters are potential applied to the electrode, ionic strength and dielectric constant of the medium. (E.g. for the most simple case 0.5 mM NaCl in water) I'm having difficulty finding a...
