The easiest way to install a packed column into a capillary column injection port is to use a “pigtail” set-up. All that is needed is a short piece of deactivated 0.53 mm ID MXT guard column tubing (which can be cut from cat.# 70045), appropriate compression unions (reducing or straight-through) and appropriate ferrules. For example, for 1/8″ packed columns, reducing union 23168 along with ferrules 20202 (for the 0.53 mm ID MXT column segment) is all that is needed. The same setup can usually be used for the detector side as well.
