Field-flow fractionation in which the physical force field is the Earth’s gravitational field.
Notes:
- GFFF can fractionate particulate matter in the micrometre size range (large microorganisms, blood cells, sediments, etc).
- Since the Earth’s gravitational field produces relatively weak forces, this mode is only appropriate for micron size particles, hence the separation is an example of hyperlayer focusing field-flow fractionation.
