Hello, I hope someone can help me!

I have a PAL COMI-xt system attached to Clarus680GC(PerkinElmer). There are "agitator on time" and "agitator off time" in SPME cycle. They work at pre-incubation time only and do not work at extraction time. The agitator rotate only one derection at extraction time. Because of that, SPME needle is bent slightly. So, SPME needle is completely bent when it is injected to GC.

I would like to know the way of working "agitator on time" and "agitator off time" work at extraction time.

Any help would be very appreciated!
