Claim 1
Independent Claim
65 words
A CONTINUOUS FLOW METHOD FOR DETERMINING SURFACE CHARACTERISTICS OF SOLID MATERIALS, COMPRISING PASSING A CONSTANT GASEOUS MIXTURE OF AN ADSORBATE AND A RELATIVELY NON-ADSORBING DILUENT GAS OVER A TEMPERATURE-CONTROLLED SAMPLE OF THE SOLID MATERIAL AT A FIXED FLOW RATE, VARYING THE PRESSURE OF THE GASEOUS MIXTURE TO DISTINCT VALUES, MEASURING THE PRESSURE AT SAID VALUES, AND ANALYZING THE GASEOUS EFFLUENT CORRESPONDING TO SAID PRESSURE VALUES.
