TheDrilledUniliner
®
is themost inert linerbecause themetal injectionport outside theglass
liner does not contact the sample path– the sample is virtually “funneled” into the column.
Also, when using the Drilled Uniliner
®
inlet seals do not need to be replaced – a savings in
maintenance cost and time. The cyclo double gooseneck liner is recommended with pres-
sure pulse conditions. Its corkscrew type sample path enhances sample vaporization and
helps prevent sample contactwithmetal surfaces below the liner. When using a gooseneck
type liner, however, routinely replacing the inlet seal below the liner is critical. Gold plated

treated linersandsealsbothensurean inert samplepath, however, Siltek

treat-
ed surfaces aremore resistant to abrasion during cleaning.
Injection port liners are designed inmany configurations, four of which are commonly used
for semivolatilesanalysis: thesinglegooseneck, doublegooseneck, cyclodoublegooseneck,
and the Drilled Uniliner
®
.While all four liner types are used for 8270 analysis, we recom-
mend the Drilled Uniliner
®
when using constant flow, and the cyclo double gooseneck with
pressure pulse conditions.

TheDrilledUniliner
®
TheDrilledUniliner
®
provides themost inert sample pathway of all inlet liners for splitless
injection techniques.This liner connects directly to the column, eliminating contact between
the active compounds and activemetal surfaces in the injector, and ensuring an inert
sample pathway for analyte transfer from the injection port to the column.
