Description
Anoxic porewater collection using Rhizon samplers at 130-180 cm depth with immediate filtration through multiple membrane sizes under N2-purged conditions to preserve redox state of Fe-bearing colloids.
Typical Equipment
- Rhizon soil moisture samplers
- valved syringes
- PES filters
- Anatop filters
- N2-purged glass serum vials
Output Measurements
- size-fractionated colloidal suspensions
- preserved redox conditions
