Commercially available trap columns < 10 mm length?

Hi,

This is related to my separation using C18 trap column in combination with a HILIC column.

For some separations, the 20 µl of RP-solvent in the C18 trap column (2.1x10 mm, XTerra C18) is too much for the HILIC separation.

Do you know if there are shorter C18 precolumns on the market? I have not been able to find it on Waters or Thermo's homepages.

SecurityGuard Standard from Phenomenex could be helpful with 4mm lenght.
