Hi all,

On our Thermo GC-III interface, the capillary that goes to the IRMS
inlet recently broke just below the actuator arm at the movable open
split.

It appears that it broke because it could not line up properly to the
lower glass tube in the split.  This glass tube I am talking of has
larger diameter fused silica glued in it, coming from the nafion trap
and N2 trap if installed.

I'm wondering if my open split itself dropped and what else may be out
of sorts.

1) Does the IRMS capillary actually go into the lower tube of the open
split when actuated?  If so how far?

2) How far is the top alignment tube (where IRMS sniffer and He
capillary enter) from the lower, main open split?  Mine was almost level
with the aluminum block with a set screw loosely holding it. 

Thanks,

Ben
