Vu-Tight Inlet Liners

-Inch Packed Injection Port Conversion
• Visually observe the Press-Tight® connection between the
column end and liner.
• Fit 0.32 and 0.53 mm ID capillary columns
(column ODs from 0.5 mm to 0.8 mm).
• Slotted top prevents obstruction of carrier gas flow.
• Two designs available.
• Operate in the direct injection mode.
Two types of inlet conversion kits are available for a
1
/
4
-inch packed column injection
port to fit either 0.32 or 0.53 mm ID capillary columns: the Vu-Tight liner and the
Uniliner® liner with adaptor (next page). The Vu-Tight liner fits directly into the
1
/
4
-inch injection port and allows visual confirmation of the connection between the
column and the liner. The Uniliner® liner and adaptor work together to allow either
direct or on-column injection when using 0.53 mm ID columns. Both systems incor-
porate a Press-Tight® connection between the liner and column inlet, minimize dead
volume, and reduce solvent peak tailing.
Features of Both Conversion Kits:
• Fit Agilent, Varian, and other common GCs with
1
/
4
-inch packed column injection
ports (with maximum insertion depth of 4 inches).
• Install easily within fifteen minutes.
• Accommodate either 0.32 or 0.53 mm ID fused silica columns
(tubing OD
≥
0.5 mm).
• Liners are deactivated and extremely inert.
• Liners designed to accept dirty samples are available for either system.
• Press-Tight® connections between the liner and column inlet minimize dead
volume, reduce solvent peak tailing, and sharpen early-eluting components.

The

-inch Vu-Tight liner fits directly into a

-inch injection port. The connection between
the liner and the column is in the GC oven,
allowing visual confirmation of the seal.
Problems, such as a crushed column end in
the Press-Tight® taper, can be detected easily,
making proper installation worry-free. The
Cyclo Vu-Tight liner prevents nonvolatile
residue from contaminating the column.
