Midway through the analysis, the argon ran out, and error code 11011: Vacuum (IF/BK) time out, vacuum too high to start turbo pump, appeared. I've attempted a full system restart, but the same error persists

  • Hello,

    Have you been able to resolve this? 

    The cones do not affect the pressure required to get the instrument turbo pump to come on and get to standby mode.  They only become an issue when lighting plasma and when the interface valve opens.  

    Most important thing is to make sure you have Argon pressure as this closes/opens the gate valve.  

    Have the meter for the IF/BK pressure visible when you turn on the vacuum.  It needs to get below 2E1 for it to start the turbo.  If not there could be a leak somewhere.  Check the lid to the mass analyzer is positioned and push down to see if the pressure drops.  Check the vacuum hose for leaks, run your hand along it and see if you can feel air pulling into the hose.  Issue could be related to a faulty backing pump, or a fault in the Pirani gauge or it's circuitry.  If you can hear the pump turn on, and the IF/BK pressure never moves it is the gauge or the IF/BK valve not opening.  These will require a service engineer to replace.
