Running ECD at higher temp?

Discussions about GC and other "gas phase" separation techniques.

Are there known negative consequences of constantly running an ECD at a higher temp? 330 degree C vs. 300 degree C for instance? This is not for the occassional bake-out but for use as a default setting.

We're kicking around the idea of running at a higher temp for PCB analysis because we've noticed a loss of sensitivity/recovery when running samples extracted from oil matrices vs. soils and waters.
I never liked to exceed the column temperature max.

I know that after oil analysis I ALWAYS had to run a bake followed by a solvent injection at regular temperature before the closing standard otherwise I would get low recovery.
queenann,

Perhaps something to consider; rather than raising the temperature, you could insulate the upper body of the detector (depending on the brand.)

Best regards,
