MICROFLUIDIC DEVICE AND DIRECT MEASUREMENT OF REACTION RATE

摘要

Embodiments disclosed herein may relate to a testing apparatus. The testing apparatus may include a sealed, chemically-resistant testing apparatus body defining a testing void; a first fluid port and a second fluid port; and a first geomaterial and a second geomaterial. The first and second geomaterials may be positioned between the first fluid port and the second fluid port and relative to one another such that a flow channel may be provided between the first and second geomaterials. The first and second geomaterials may be coupled to a testing void interior surface so as to restrict flow to the flow channel between an upflow region and a downflow region of the testing void. The first and second geomaterials may be comprised of a natural formation material.
