          Appeal No. 95-0339                                                          
          Application 07/881,941                                                      


               1.  A system for detecting the presence of contaminants in             
          supercritical fluid, said system comprising:                                
               a processing vessel which contains supercritical fluid;                
               sampling means for removing at least a portion of super-               
          critical fluid from said processing vessel and introducing said             
          portion as a sample stream of supercritical fluid into a vessel             
          having walls defining a contaminant measurement zone;                       
               pressure releasing means for maintaining the pressure within           
          said measurement zone at or below the level required to convert             
          said sample stream into a gas wherein said contaminants present             
          in said sample stream remain in a non-gaseous form;                         
               an attenuated total reflectance plate having an exterior               
          surface located within said measurement zone wherein said non-
