10. The data analysis list for the sample is performed.
11. If there is another sample in the list, the work cycle, starting with step 1, begins again.
Reduced Time Cycle
A reduced time cycle is available for the STA 6000, TGA 4000, DSC 4000 and DSC 6000.
This feature is accomplished by using either a Sample Group or by doing successive Load
Sample commands without an explicit Return Sample.
If you do this, the steps where the furnace lids are replaced are eliminated and the next
sample is immediately loaded.
The procedure below is for the work cycle for DSC 4000/DSC 6000 for multiple samples using
the reduced cycle time.
1. Start the play list. Your play list may have an explicit Load Sample command, or, if
using a Sample Group, the entry Sample List implies Load Sample. Upon reaching this
line in the list, the gripper swings around to remove the upper lid and place it on the
ring.
2. The gripper then removes the lower lid and places it on the ring.
3. The gripper retrieves the sample pan and places it in the furnace.
4. The lower lid is placed within the furnace.
5. The upper lid is placed on the furnace.
6. The gripper returns to the home position.
7. The method runs.
8. The data analysis list for the sample is performed.
9. The system removes the upper lid and places it on the ring.
10. The system removes the lower lid and places it on the ring.
11. The sample pan is removed from the furnace and returned to its place in the tray.
12. The gripper retrieves the next sample pan and places it in the furnace.
13. The system places the lower lid back into the furnace.
14. The upper lid is placed back on the lid holder.
15. The gripper goes to the home position.
The procedure for the STA 6000/TGA 4000 is similar to the procedure above.
