               first and second elastomeric gaskets,                                  
               (i) said male screw threads on the primary container                   
               body, (ii) said first end cap component, (iii) said                    
               primary cylinder portion of the first end cap                          
               component, (iv) said concentric cylindrical hole                       
               therethrough, (v) said exterior and interior walls of                  
               the first end cap component, (vi) said female screw                    
               threads on at least a zone of said interior walls,                     
               (vii) said retainer portion of the first end cap                       
               component, and (viii) a hole therethrough all forming a                
               torque-limited-screwed, temperature-stable sealing                     
               container around the sealing array of the fluoride-                    
               sensing crystal and the first and elastomeric gaskets.                 
                    29.  (allowable)  A free-fluoride-ion-sensitive                   
               electrode according to claim 24, wherein the means for                 
               dividing the central cavity of the primary container                   
               body is a plug of solidified potting resin through                     
               which electrically conducting lead component (H)                       
               passes.                                                                
                    30.  (allowable)  A free-fluoride-ion-sensitive                   
               electrode according to claim 29, wherein: the central                  
               cavity through the primary container body has an                       
               enlarged zone which has two ends, both ends of said                    
               enlarged zone of the central cavity being within,                      
               rather than at either end of, the central cavity and                   
               both of the ends of the enlarged zone being between an                 
               end of the primary container body and the liquid- and                  
               vapor-tight portion of the central cavity that contains                
               the first ionic solution of known composition, said                    
               enlarged zone being larger in cross-section than is                    
               another portion of said central cavity that is situated                
               between the enlarged zone and said one of said ends of                 
               said central cavity; and at least a portion of said                    
               plug of potting resin fits within said enlarged zone of
