It appears that the collision cell epc has shut down for some reason. Check to make sure that you have pressure and sufficient N2 suppply.The GC is in shutdown. Close the software and power cycle the GC. Check to make sure that the Cell gas controls after the power cycle.

Thank you for your answer, I have check that i have run out of nitrogen,
so the collision cell epc has shut down as there isn´t enough nitrogen,
but is strange because i just change the bottle one week ago. I have
order a new bottle so i can check the reason why i spend so many
nitrogen in only one week.
