Packed Column Inlet Conversion
*DI = direct injection, OC = on-column injection
Note: a Uniliner liner must be used with a Uniliner liner adaptor (cat.# 20310 or 20311) for
1
/
4
-inch injection ports.
Remember to include a liner adaptor when ordering a Uniliner liner, unless you are purchasing replacement Uniliner liners.
Uniliner® Liner for
1
/
4
-Inch Packed Injection Port Conversion
• Reduces solvent tailing.
• Versatile—0.53 mm ID version can be used in the direct (DI) or on-column (OC)
injection mode.
• Incorporates a gentle taper that seals the column and reduces dead volume in direct
injection mode.
• Available in various designs.
On-column injections can be performed only with 0.53 mm ID columns because
26-gauge needles do not fit into the bore of 0.32 mm ID columns, or into the Unliner®
liner taper.
5 mm Uniliner® liners fit into the
1
/
4
-inch
Uniliner® liner adaptor, which fits into a
1
/
4
-inch injection port. The Uniliner® liner can
be inserted in one direction for direct injec-
tions or inverted for on-column injections.
Because the
1
/
4
-inch injection port ferrule
seals against the metal liner adaptor surface,
it is virtually impossible to crack the glass
Uniliner® liner during installation.
