Transitioning from Packed to Capillary Column (GC 7890B)

Does anyone have experience transitioning column types from packed to capillary on the GC? Our current inlet is purged packed and solvents are polar, so inlet volume is a concern. Any tips or recommendations on how best to handle this type of transition would be very appreciated. Thanks!

  • Hi

    If you want to configured capillary inlet by removing purge packed inlet then you have to buy complete capillay inlet assy with EPC..

    And for this job, need specialty to install and configure it so need local agilent support..

  • We won't know if a new inlet is needed until trying (with our solvents we are borderline for volume). From what we've been told we may not need a new inlet. Do you have any experience in how the operational procedure changes between a packed and capillary column? 

  • There are big difference..

    Major is packed column use high flow like 10/15/30ml while capillary column used to maximum 5ml of flow generally.

    Configuration is totally different..

    By the way, why u want to change it...Any specific application requirement?

  • Find above detail of all type agilent inlets and there use and differences...
