Dear Friends
How many of you have measured the shim coil resistances on the
Bruker BOSS-2 shim stack and can you kindly tell me how far off these
values were from the (average) expected values ? I used the following
webpage of bruker-biospin to obtain the latter information :
http://www.bruker-biospin.com/nmr/techsupport/systems/shim_coil.html
I am having trouble with one of my Avance-AV 500 MHz spectrometer's
shim system and I am apparently hitting the maximum current allowed by
BSMS although there are other indications that make me think that this
is not the case. On this system, many of the shim coil resistances that
I measured are smaller than the above values tabulated by Bruker, by a
factor of two. On the other hand, on my older DRX 500 system, the shim
coil resistances are higher than the mean by 10%.
I will be very grateful for your input on this.
Regards
rajan
