Agilent 7980A PTV injection

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