Measuring Droplet Density

  1. May 28, 2015 #1
    I need to measure the density of aqueous microdroplets in oil. My first idea was to obtain a set volume of the droplet-in-oil mixture and weigh it to obtain the density, weigh the same volume of oil without droplets, then estimate the volume of the droplets so I can work out their density.

    Estimating the volume of the droplets is turning out to be trickier than expected.

    Does anyone have any ideas as to how I can measure the density and / or volume of microdroplets in oil?

    Thank you

    How large are the droplets (rough estimate)?

    Can you take a small (known) volume and squeeze it between two transparent plates to make the droplets countable with a microscope?

    Or maybe you could centrifuge the oil to make the droplets go on the surface. But it all depends on the size. mfb already asked.
