DE3230507

A process for the formation of a sample which does not require any external energy for determining the content of dissociable polar liquids in gases, expanded bodies, pouring charges of granular material, or electrically non-conductive liquids. The invention further relates to the provision of a sample probe which does not require external energy and which is applicable to the implementation of the process. A powder having a grain size in the range of between about 0.001 to 1 mm of an electrically deformable material having a crystalline or amorphic structure with at least a partial ionic bond and a specific resistance of at least 105 Ohm/cm is compressed between two electrodes under a pressure of at least 100 bar, and continually maintained under pressure, whereby at least a portion of the components maintaining the powder under pressure is permeable to the moisture encompassing the sample.
