Good afternoon.

We don't run GB all that much, and after nine years and ~5000 samples, 
the sample needle finally cracked and started leaking. I see Thermo 
provided ferrules with the spare needles that came with the instrument, 
but absent is size info.

The one for fused silica appears to be a Valco FS 1.5, and

The one for the stainless capillary appears to be an SGE GVF16-1/32 
(0.8mm), Part No: 072655. 15/85% graphite/vespel.

Please will someone confirm these parts for us, for our future reference?
