Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Contact Metamorphism of the Mancos Shale: Impacts on Solute Release and Weatherability in the East River Valley, Gothic, CO (2018). Implementations in other papers (listed below) may differ.

1. Flow-through experiments
   Fisher Scientific FH100 peristaltic pump was used to pump synthetic rainwater at fixed flow rates of 1 mL/min or 2 mL/min into columns with flow from bottom to top. Influent and effluent tubing was constructed of Thermo Scientific All-Purpose Tubing size 14. All column scale experiments were conducted in triplicate with new columns manufactured for each replicate.
   Quantities: Flow rates of 1 mL/min and 2 mL/min, three replicates per conditionDuration: Experiments continued until steady state reached, typically 2-10 pore volumesConditions: Ambient temperature ~20°C
   Equipment: Fisher Scientific FH100 peristaltic pump, Thermo Scientific All-Purpose Tubing size 14
