    RADWAG moisture analyzer comprises two components: a precision balance and a drying chamber. Compared to standard moisture content determining methods, the measurements with application of RADWAG moisture analyzer is much quicker and does not require additional mathematical calculations (a result of moisture content is previewed on an ongoing basis during product testing process).
  • Page 68 Final measurement result is vastly conditioned by precise and considered sample preparation. A sample used for analysis has to represent the total structure of tested material. Sampling process should determine: sampling means, sample disintegrating, particle size after disintegration, sample uniformity and other. The sampling process should be carried out as quickly as possible, so that a sample does not loose or absorb humidity from surrounding area.
  • Page 69 Liquid substances It refers to liquid substances, which by creation of drops on their surface, caused by surface tension, may render difficulties in drying process. In such cases, it is proved to use a glass fiber filter to shorten measurement time. The filter causes separating tested liquid around the fibers, and increasing active evaporating surface.

  • Page 70: Selection Of Drying Parameters

    13. SELECTION OF DRYING PARAMETERS 13.1. Selecting optimum sample mass Sample mass influences the accuracy of measurement result and measurement time. Higher mass of a sample, causes higher amount of water (moisture content) which needs to evaporate, and therefore measurement time is also longer. Obtaining short measurement time is feasible in case of small sample mass, but sample mass cannot be too small, as it may negatively influence required measurement accuracy.
