    TriStar II 3020 Service Analysis Sequence 3. THE ANALYSIS SEQUENCE The analysis sequence describes what is taking place throughout the instrument during an analysis.The instrument schematic, shown below, will be used to show the state of the system components during the various phases of an analysis.

  • Page 20: Analysis Technique

    Servo Analysis Technique The TriStar II 3020 Analyzer uses physical adsorption and capillary condensation principles to obtain information about the surface area and porosity of a solid material. The analytical technique is simple: a sample contained in an evacuated sample tube is cooled (typically) to cryogenic temperature, then is exposed to analysis gas at a series of precisely controlled pressures.

  • Page 21: Analysis Sequence

    TriStar II 3020 Service Analysis Sequence Analysis Sequence 1. Create and save up to three sample files for use during an analysis. 2. Place a plug in any port that is not being used for analysis. 3. Prepare samples to be analyzed. This may include weighing the sample and degassing the sample.
  • Page 22 Analysis Sequence TriStar II 3020 Service 7. The system begins to evacuate the manifold at a rate and time specified in the sample file. 8. All valves close, then the N2 valve opens and the Po tube is filled to the target pressure.
  • Page 23 TriStar II 3020 Service Analysis Sequence 10. A series of manifold dosings and port equilibrations begin to take place on each port to prepare for analysis under cryogenic conditions. Helium warm free space is measured. Then the elevator is raised to measure cold freespace.
  • Page 24 Analysis Sequence TriStar II 3020 Service 11. Helium is evacuated from the samples and the Dewar is lowered if specified in the sample file. 12. Samples are evacuated for the amount of time specified in the sample file. Jul 09...
  • Page 25 TriStar II 3020 Service Analysis Sequence 13. The Po tube is dosed and allowed to equilibrate. 1000.00 14. If the pressure does not change measurably, the Psat measurement is taken. If the pressure changes measurably, another dose may be required.
  • Page 26 Analysis Sequence TriStar II 3020 Service 15. After evacuation, the analysis phase begins. The instrument starts dosing to the set point specified in the sample file and continues until the specified number of data points have been collected. Data points are displayed in a graph as they are collected.
