TOP VIEWOF 86tOCCOLUMN OVEN
(WITH
COLUMNOVEN LID
REMOVED FOR CLARITY)
The product of ten years of gas chromatograph design andmanufacturing, the 8610Ccolumn
oven is an insulated design that
permits
operation from ambient temperature to4OO·C, with rapid
ramping tomaximum temperature and rapid cooling to
initial
oven temperature when operating in
temperature-programmed mode. The high-output heating element permits heating at
up
to 4O'C per
minute, and the assistedcooling
fan
configuration permits return to50·C from 250·C
in
fiveminutes
or less. Theoven lid is equipped with an exhaust vent that speeds the evacuation of heat from the
oven during cooling. Theovenmay also
be
operated isothermally with excellent stability.
The open
air
circulation design eliminates gradients throughout the ovenwhichcould affect
performance. Prepunched openings in
both
the left
and
right oven
wa11s
permit
easy
future
implementation of accessories anddetector additions. Upto four detectors may bemounted on the
rightoven
wall
formaximum analytical versatility. The outlet from non-destruetive detectors, such
as the PID, are routedwithin the column oven for convenient series detector operation. Thecolumn
ovenmay beequipped with an
optional
second direct
on-column
injection
port
forusewith a second
analytical column, and also may
be
equippedwith a heated injection
port,
with or without
split-splitless capability.
