Is the gravimetric water content true? NIR spectroscopy gives an answer for polymers and composites

The more water is inside the polymer, the more intense the peak.

A common way to measure water content is by weighting the polymer or a composite sample, using a gravimetric method. This method often overlooks that there is already some water inside the initial (mistakenly called “dry”) material.
