Hello,

I need to remove the back split/splitless injector from a 6890 Agilent GC and reinstall it on an other 6890 GC.
But yet, in my first GC, i have a hole without insulation inside. I don't want to reinstall an other injector, i just want to fill up the hole.

Anyone know a reference of agilent insulation? or wich material use agilent for insulation and i will try to fill up the hole myself.

I don't find the reference in my Agilent catalogue...

Thanks for your help

In 2004 I "inherited" from Manufacturing a 5890 GC which had its FID and top insulation contaminated by oil in the air line that had been plumbed to the FID (that's another story).

Anyway, I cut out the oil-soaked insulation (which smelled real bad as the oven got over 190C) and filled the gaps with insulated fiberglass cloth tape, like 1 inch wide. I used Fisher #01-472A, but I didn't check if that part number is still "live", but that product should be available.

I usually use glass wool when I need instrument insulation - it is usually around the lab somewhere - prep labs often use it for filtering, etc.

You can get ceramic wool from RS components online, either sheets or loose fluffy bits.

Amazing what this genetic engineering can do to sheep....

Ha, ha, ha ... excellent.

It stops them shrinking in rainy weather

Glass wool sounds like a great idea. However a lot of "scientific " glass wool suppliers have now uprated the associated hazards statement concerning inhalation risk. The split insulation set is not overly expensive so I would imagine that the non-hole version will be cheap.
