Abstract Samples of materials are immersed
in a liquid nitrogen bath until the sample temperature is stabilized. A
dielectric moisture meter is used to measure the samples before and after the
liquid nitrogen treatment. From these two measurements and a normalized
calibration curve (taken from any other sample of the same material) it is
possible to determine the percentage moisture content independently of the
sample basis weight for given conditions. It is shown that the method can be
applied to butter fats, petroleum jelly (vaseline),
greases and paper. It may also be possible to extend this method to other
materials and products. |
