If I might make a suggestion: With lenses and cameras as cheap and
available as they presently are and video algorithms as easily
obtained, I would think about using two cameras to photograph the nano
droplet (these are generally round but sometimes they are flattened
due to surface attractions) and computer imaging to measure the actual
volume. This has the advantage of not requiring the density which is
never accurately known for most liquids.

This system might be presently available somewhere since I don't think
that I just came up with that off the top of my head.
