This Upchurch Scientifc

ultralow volume guard column (1.0 mm ID x
2 cm length) is ideal for narrow-bore chromatography. The unpacked
guard column allows you to exactlymatch the chemistry of your column,
resulting in optimum column protection. The total packing volume of
16.2 µL ensures maximum column effciency and analytical column
protection. The column can be easily dry packed using the specially
designed funnel (C-128-20). A 3 g bottle of our C18 packing material
will pack this column more than 120 times.
Frits often become plugged before a guard column is contaminated.
The two 0.5 µm frits included with this guard column can be changed
in minutes. Optional 2 µm frits may be purchased separately (C-408).

Easy to pack

The C-130B is our most popular guard column. HPLC users fnd this
column easy to pack and extremely economical. This narrow-bore short
column (2.0mm ID x 2 cm length) creates only a slight pressure increase
with virtually no detectable theoretical plate loss when used with a
3mm IDor larger column. The 2 µm frits are easy to change, prolonging
the life of the guard column. With only 62 µL packing volume per
guard column, a 3 g bottle of packing material will pack about 30
guard columns.
For convenience, we offer the C-135B kit with two unpacked guard
columns and a ten pack of frits. With two guard columns, there is always
a back-up available to help eliminate downtime.
