Abstract
A thermo-gravimetric analysis system includes a chamber having an interior; and a sample crucible connected to and inside of the chamber, the sample crucible configured to hold a sample material. The system further includes a reference crucible connected to and inside of the chamber; and a metal organic framework (MOF) crucible connected to and inside of the chamber, separate from the sample crucible, the MOF crucible including an MOF material.
