• Protect your capillary<br />
column investment<br />
• Ultra-low volumes maintain<br />
capillary efficiencies<br />
• Matched media retains<br />
selectivity<br />
• Simple finger-tight<br />
connection, no holder<br />
needed<br />
Alltech’s Cap-Guard is the<br />
ideal solution to extend the life of capillary <strong>LC</strong> columns.<br />
Smaller than a fitting, patented* Cap-Guards connect<br />
directly into the inlet of your column for a zero-dead<br />
volume connection every time. The floating stainless<br />
steel stem self-adjusts to any 10-32 port. This simple,<br />
disposable design requires no holder – a great option<br />
for efficient labs that want to save money. Cap-Guards<br />
are available with all of Alltech’s capillary <strong>LC</strong> column<br />
packings.<br />

• Zero dead volume design<br />
is ideal for micro-<strong>LC</strong><br />
columns<br />

Designed in the shape<br />
5492<br />
of an HP<strong>LC</strong> compression fitting, the Alltech Micro-<br />
Guard patented* guard column is simple to use with<br />
any analytical column. It requires no holder, seals, or<br />
complicated parts to connect. The innovative 2-piece<br />
construction contains a self-adjusting stem that adjust<br />
to deliver a zero dead volume connection every time.<br />
Micro-Guards are packed with general purpose, 25-40µm<br />
packing, and therefore can be used with a variety of<br />
columns.<br />
