The Drilled Uniliner
®
inlet liner is the
first inlet liner to allow direct injections
in EPC systems!
INNOVATION
linearity values (%RSD) obtained using a Drilled
Uniliner
®
liner and Rtx
®
-CLPesticides columns.
Equivalent results are obtainedwith
Stx
™
-CLPesticides columns.
When using a Drilled Uniliner
®
liner, the efficient
transfer of sample from the injection port to the
columnmight allowmore nonvolatilematerial to
enter the column. Formany samples this will not be
an issue, especially if solid phase cleanup is per-
formed. Using a guard columnwill helpmaintain
the analytical column. When necessary, the guard
column can be trimmed to remove the portion
where the nonvolatilematerial collects (usually the
first 6-12 inches).
Conclusion
TheDrilledUniliner
®
liner provides the advantages
of both direct and splitless injection liners. The liner
provides amore inert sample pathway to transfer
the sample from the injector to the analytical col-
umn, and it helps eliminate injection port discrimi-
nation. ADrilledUniliner
®
liner will reduce the
detection limits for injectionsmade on a splitless
injection port, without the need for an on-column
injector.
