The Narrow Bore Capillary FID GC System includes everything you need for ultra high
performance narrow bore capillary chromatography. In addition to a wide range of
general gas chromatography applications, the Narrow Bore Capillary FID GC System is
excellent for environmental testing and quality control applications.
The On-Column Programmable Temperature Vaporization (OCPTV) injector allows larger and simpler liquid injections
than are otherwise possible with narrow bore columns. Like a traditional heated Split/Splitless injector, the OCPTV has a
spilt vent and needle valve for venting solvent while concentrating sample. Unlike a heated Split/Splitless injector, the
OCPTV vents the solvent without without rapid vaporization. Carrier gas flow is programmable from the PeakSimple
data system.
The OCPTV discriminates in favor of
semi-volatile analytes with boiling points
higher than C
8
. The chromatogram at

organics (C

-C-

). The OCPTV
causes the analytes to focus on the
analytical column, resulting in sharp,
well-defined peaks.
Traditional heated split injectors can
usually only handle 1-2µL injections.
The OCPTV's ability to accommodate
larger (1-20µL) injections allows for
detection limits an order of magnitude
lower. For more information on the
OCPTV, see
