I'm running O2 with our Gasbench coupled with a Delta XL Plus Mass
Spectrometer. Lately I've seen an offset in the 33 peak from the 32 &
34 peaks in the traces, with the 33 value being measured on the front
edge of the peak and not on the 'flat' top. The 33 voltages are not
stable and delta 17 O measurements are erratic because of this.
I'm wondering if this is a problem with the magnet setting, a dirty
source or just a tuning issue.
Any ides would be appreciated.
