  • Method of wood chip moisture analysis
    Patent number: 6131442
    Abstract: A method of determining the moisture content in wood in which a sample of the wood being tested is first frozen with liquid nitrogen, homogenized and a test sample is placed in a Karl Fischer titration system. The test sample is placed into a solvent solution and the reagent or titrant is progressively added to the solvent solution as the presence of moisture from the wood sample is detected. Once the moisture has been titrated from the solution the moisture content of the wood is determined based upon the amount of reagent dispensed into the titration solution.
