Type of article: Article

Summary

THE METHOD IS AN ABSOLUTE METHOD UTILIZING A TRANSIENT HOT WIRE, A MINICOMPUTER AND A DIGITAL VOLTMETER. MEASUREMENTS ARE MADE WITH A 12.7 MICRO M DIAMETER PLATINUM WIRE AT REAL TIMES OF UP TO 1 SECOND. THE CELL CONTAINING THE CORE IS DESIGNED TO ACCOMMODATE PRESSURES FROM 0 TO 70 MPA AND TEMPERATURES FROM 70 TO 320 K. OXYGEN WAS MEASURED OVER A WIDE RANGE INCLUDING THE DILUTE GAS, THE MODERATELY DENSE GAS, THE NEAR CRITICAL REGION, THE COMPRESSED LIQUID STATES, AND THE VAPOUR AT TEMPERATURES BELOW THE CRITICAL TEMPERATURE. PERFORMANCE CHECKS WERE CONDUCTED WITH NITROGEN, HELIUM AND ARGON.
