Wall-Wash Data Archive

The wall-wash, electrolyte-sampling kits are described here. The analytical methods employed are detailed here. The entire dataset for wall-wash analyses carried out to date can be found in the table below.

Electrolytes concentrations are recorded in units of nanomoles/sqcm.

Note that the table provides extensive ordering and filtering capabilities. Note also that data can be exported.

I’m happy for people to make of this data what they will, and to use it as they feel fit. However, if published elsewhere, an acknowledgement would be nice.
