Dear List Members,

  My liquid nitrogen refill device sensor on the Kiel was acting up for a
while and now a connection has come loose and the sensor is totally non-
fuctional.  This has happened 2 times in 3 months.

  I've contacted Finnigan to order the part and I am also looking for a
local source as well as any info others might have about this problem (to
repair it or other solutions).

Thanks for any info you provide, Olivia Gibb.
