Agilent 7980A PTV injection

[Xarix]

Can we use a peltier cooler on Agilent 7980A instead liquid CO2/N2 for the injector cooling?

Thank you

No. CO2 and N2 cooling use the depresurisation of the gases to cool the injector. A peltier cooler either directly cools a metal block or a liquid that is pumped round. Do you actually need additional cooling ? Most PTVs can be air cooled provided you don't need a sub ambient start temperature

I have available for sale 2 Gerstel CIS 4 injection ports with the coolers, we just removed them from a 7890 last week. I could give you a really good deal, if you are interested please let me know.
