Teknokroma also offers the option to build your column with both guard and after column. to order a column with an integrated guard column use the below formula:
TR-G[ P/N Column ]-[ meters precolumn ]-[ meters post column ]

with pre and poscolumn:
Meta XLB 30 m x 0.25 mm x 0.25 µm + 5 meters pre column + 1 meter post column P/N TR-G330232-5-1
