restrictor capillary tubing for GC/MS
Posted: Tue Oct 23, 2012 1:11 pm
Hi all I have a quick question.
As I mentioned in previous posts I have the Agilent Quickswap system and am planning on converting to hydrogen. The smallest diameter restriction capillary they sell is 92 um. That is still a bit wide for me and I'd have a 1.89 ml/min flow into the MS at 4 PSI and 280 deg transferline temp. I was wondering if someone sold smaller diameter tubing and all I would have to do is install a siltite ferrule on one end and cut to length (score and break) on the MS source end.
