For coupled TGA/MS runs (either individual or multiple samples), the method
used should have a 5 minute Argon “purge” at 25 °C to equilibrate the signals
detected by the MS. For further TGA/MS instructions, please refer to Section II.
When creating a new method/using an old method, make certain that the pan
being used matches the pan as outlined in the method. The most commonly used
pans are the 70μl Alumina pan and the 100μl Aluminum pan. The alumina pans
are reusable and should be cleaned after use; the aluminum pans can be disposed.
The maximum temperature for the alumina pans is 2000 °C; the maximum for the
aluminum pans are 640 °C. DO NOT TAKE THE PANS TO THESE
TEMPERATURES.
19. Once a method is selected, place a sample name into the field. Sample name should be
placed as follows: YYMMDD_NOTEBOOK CODE_TGA
The weight can be left blank. The position should match the position on the carousel
where you place the pan. Click Send Experiment.
For position 1 on the carousel, the position inputted is 101, for position 2, 102,
position 10, 110, etc.
20. If more experiments need to be added to the queue, follow steps 6 & 7 (step 6 only needs
to be followed if running a different routine).
21. Open up the argon tank.
22. Click on Experiment – pending on the left tab of the window. Highlight all experiments
and right click and select Weigh In Auto…
