Dear Jim,


The FS capillary is a standard deactivated 0.32mm ID/ 0.44 mm OD (=> requires a ferrule with 0.5 mm hole).
Thermo uses the Valco FS 1/16” type ferrule here to reduce the dead volume and perhaps because it uses a Valco connection at the bulkhead (in reality if works also with standard SGE GVF ferrules)

The SS capillary has 0.5mm ID / 0.75mm OD (=> requires a ferrule with 0.8mm hole).
Provided by Thermo is a standard SGE GVF 16-008 (hole with 0.8mm).

I van send you a ppt file that describes how to make your own needle (also available from the wiki). 
However, 5000 samples in 9 years…it might be easier to buy them. :-)
