The moisture content can be measured by means of many commercially available devices : loss-on-drying (LOD) or loss-in-weight, ‘manometric method’ and ‘Karl-Fischer tritation’ systems are widely in use in the industry and in particular in the plastics industry . To eliminate any possibility of error, the specimens are to be taken in sufficient depth onto a hopper, and must be stored in an appropriate sealed container, usually sealable bags or laboratory hermetic containers. These devices system usually requires specific knowledge of laboratory and in addition, the result is often particularly affected by the method of sampling, environments and human errors.
