Analysis Modes
The analysis program supports four analysis modes:
- Standard. See Perform a Sample Analysis.
In Standard mode, the system performs nitrogen, or similar gas, analyses at 77 K. All analyses must use the same gas. Samples can be removed and added to any of the ports without disturbing the analyses being performed on other ports.
- High Throughput. See Perform a High Throughput Analysis.
In High Throughput mode, up to six nitrogen, or similar gas, analyses are started together. All analyses must use the same analysis gas and the same Psat gas, which may be different from the analysis gas. Once a set is started, no other samples can be started until the set is complete. The data collection is done in parallel. This mode also supports measured freespace.
- Krypton. See Perform a Krypton Analysis.
In Krypton mode, the analyses are started together. Port 2, 4, or 6 (depending on system configuration) is used to store Krypton for dosing. The data collection is done sequentially — one analysis starts and completes before the next is started.
- Micropore. See Perform a Micropore Analysis.
In Micropore mode, up to six analyses are started together. Once a set is started, no other samples can be started until the set is complete.
Each analysis port is equipped with an elevator that raises and lowers the analysis bath fluid dewar automatically. A removable shield to enclose the dewar should be used for safety purposes.
The sample saturation pressure (Psat) tube is located next to the sample analysis port. Gas inlet ports and cable connections are located on the side panel of the analyzer.
The use of isothermal jackets maintains a stable thermal profile along the full length of the sample and Psat tubes.
