1. Optimizing PToF timing and averaging and saving

2. Requirements for Zeppelin-AMS settings
As short as possible saving intervals
V- and W-Mode MS
-> wait time for TPS required
V-Mode PToF
Good size resolution

3. Big m/z range or good size resolution?
Raising nr of samples (m/z range) increases memory requirements
Raising ToF Spectra/Chopper (size resolution) increases memory requirements
Solution: Split V-Mode into MS and PToF menus
Putting them in one calibration group transports m/z calibration settings, IE calibration results, etc. made with MS menu to PToF menu

4. V-Mode MS timing

5. V-Mode PToF timing

6. TPS wait time?
Now the switch between V-MS and V-PToF also waits for TPS
unnecessarily decreased duty cycle
Solution: turn off TPS wait time and add 4 seconds wait time at start of every run for V-MS and W-MS

7. TPS wait time?
Now the switch between V-MS and V-PToF also waits for TPS
unnecessarily decreased duty cycle

8. V-Mode
22. November 2018 8

9. W-Mode
22. November 2018 9

10. Are these acceptable times?
Full cycle of 90 seconds
about 9% TPS wait time
more time lost due to chopper movement (open <-> closed)
