External energyless sample for determining the content of dissociable polar liquids
First Claim
1. In a process for the formation of an external energy-less apparatus for the determination of the content of dissociable polar liquids in gases, expanded solid bodies, charges of granular material, or electrically non-conductive liquids;
- the improvement comprising;
compressing powder having a grain size in the range of between 0.001 to 1 mm from an elastically deformable material of crystalline or amorphic structure with an at least partially ionic bond and a specific resistance of at least 105 Ohm/cm between components including two electrodes under a pressure of at least about 100 bar; and
continually maintaining the powder under pressure whereby said permanently maintained pressure elastically deforms said powder and upon adsorption and desorption of molecules of said polar liquid produces a continuous current dependent upon the amount of adsorption and desorption of molecules of said polar liquid within the gas, liquid or solid being tested thereby indicating the content of polar liquids therein, and whereby at least a portion of the components maintaining the powder under pressure is permeable to moisture encompassing the apparatus.

Abstract
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.

3. An apparatus for the determination of the content of dissociable polar liquids in gases, expanded solid bodies, charges of granular material, or electrically non-conductive liquids, wherein said apparatus does not require external energy;
- comprising two oppositely spaced electrodes defining a space therebetween, at least one component pressure-tightly enclosing at least a portion of the space intermediate the electrodes; and
a powder within the space subjected to pressure, said component permanently maintaining said powder under pressure, said powder having a grain size in the range of between 0.001 and 1 mm, consituted of an elastically deformable material of crystalline or amorphic structure with an at least partial ionic bond and a specific resistance of at least 105 Ohm/cm, wherein at least one electrode and at least a portion of the component pressure-tightly enclosing said sapce is permeable to moisture encompassing the apparatus, whereby said permanently maintained pressure elastically deforms said powder and upon adsorption and desorption of molecules of said polar liquid produces a continuous current dependent upon the amount of adsorption and desorption of molecules of said polar liquid within the gas, liquid or solid being tested thereby indicating the content of polar liquids therein. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
