5.4.4 Entering Saturation Constants
Henry's Law is applicable to ppmw moisture measurements in all organic liquids. It states that, "At a constant
temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the
partial pressure of that gas in equilibrium with that liquid." In other words,
