Thanks for the reply. Yes I agree using a tube may influence the path of the falling dust. I could try allowing a larger distance for the dust particles to fall from. However unfortunately I only need to get a very small amount of dust on the surface. And I have only a limited supply of this...

Thanks. Sorry but this is not even close to CSI work. I will try out what you have said and see if that works.

Yes sorry for not being more specific earlier. The dust is dust from soil (contaminated with metals). After distributing it evenly over a surface (I am thinking alfoil) a hand press would be done so that this dust then adheres to the hand so I can eventually calculate the transfer rate of the...

Thanks. Yes another issue I face is I have a known quantities of dust (0.08g and 18g) which I want to distribute over individual surfaces evenly so I have to somehow ensure all of this dust gets transferred onto the surface.

Thank you. So after removing the charge from the surface dust should remain evenly distributed?

Hi, I am more familiar with the world of biology and chemistry, however I am trying to come up with a method to evenly distribute dust over a surface area which may require a bit of Physics help. I was wondering is there any way of say, positively charging an aluminium foil surface and...
