Subject: [ISOGEOCHEM] replacement of resistors and capacitors on single amplifier board for Delta V Advantage
Dear Isogeochem members,
Unfotunately I have to deal with a lot of 13C and 15N highly enriched
samples. I want to change the resistors and capicitors on the single
amplifier board of our Delta V Advantage. Does anyone have experience in
doing so and do you know a good and relyable source for high-impendance
resistors for a reasonable price (Thermo Sweden wants around 2000 €). I
need the combination 1 GOhm/150 pF and 10 GOhm/15 pF.
