SSHCZO -- Soil Geochemistry -- Shale Hills -- (2015-2015)

Colloids were isolated from SSHO soil samples collected for another study. Colloids were isolated by shaking soil in Milli-Q water, centrifuging to remove particles >1 micron, and then passing the suspension through a 1 micron nylon mesh. Certain colloids samples were further segregated by settling at room temperature over a 17 cm settling distance. Settling times are indicated in the data file. Splits of the colloidal suspensions were filtered to < 3kDa to assess truly dissolved constituents and that is the data collected here. The column FieldLabel matches samples between files.
