Kendra-

I was wondering on how you source problem was sorted out. I seem to be
having difficulty with getting a good filament from Finnigan. The first one
I put in worked great for 10 days and then lost linearity and sensitivity
so I have been attempting to replace it by so far I have recieved 3 add'l
bad filaments from Finnigan (2nd one was broken, third was not centered in
the openning and was tilted 20 deg, forth not much better than the 3rd, but
I tried it with no luck. I was wondering if your problem was linked to a
bad filament?

Cheers,

Dave
