Hello

As far as I know needle for transfer lines can be from 7694 HS:

-Needle, headspace transfer line, deactivated 0.5 mm OD 2322590004

-Needle for transfer line, 0.25 mm ID, 0.5 mm OD, nickel 301-016-HSP

-Needle, headspace transfer line, deactivated 0.7 mm OD 2322590005

-Needle for transfer line, 0.4 mm ID, 0.8 mm OD, nickel 301-015-HSP

You can attach transfer line from HS to GC inlet lines and you don't have to use this needles anymore.

Hi ,

Thanks for the info , though arnt these needles for the 7694 transfer line setup ?

the 7697 is slightly different and has a supporting bracket and fitting round the needle and I cant see how the broken needle can be replaced with a new one
The needle then goes into the inlet
