￭ Guide the column inlet capillary and the column outlet capillary
through the two capillary feed-throughs at the left and right side
of the oven door.
The column holder can hold two columns with a maximum length of 150
mm. If one of the columns is an iColumn, the system ensures that the
oven is not heated up higher than the standard operating temperature of
the column. You can also use columns without chip, in this case you have
to set the maximum oven temperature manually.
The second bore hole of the column block can also hold additional col-
umns and/or guard columns with a total length of 150 mm. For applica-
tions requiring a 250 mm column, you can combine a 150 mm iColumn
with a second 100 mm column and an on column guard column. The fol-
lowing figure illustrates how the preheating capillary and the columns are
connected.
