[Ifeffit] Fluorescence sample thickness

[Christopher Patridge]

Hi Rachel,

Do you have a good idea of the approximate mass percent of the elements you’re probing.  A little more information, (edge, suspected surrounding environment) would probably get you a much better answer.  When you say ‘control the concentration’ do you mean you can dictate how much sample you put in the capillary tube or how much of the absorption element?  Otherwise, really the only answer is, “it depends.”

hope that helps,

Chris

I anticipate being able to control the concentration fairly easily, and I’m trying to figure out what the best capillary diameter would be. Is there a good way to figure this out?
