RATES TABLE: A table of
all
of the 8610C gas chromatograph's detector and
special feature gas flow rates is provided on the right chassis panel of the GC.
This
table bears the
recommended gas flowrate settings forevery feature
that
the particular
gas
chromatograph
is
equipped with. All detectors requiring supportive gases, such as hydrogen and compressed
air
(in
addition to carrier gas) for FID, FPD, NPD, and DEleD operation
will
have their suggested
flows printed here for easy reference. Any special purpose gases requiring specific flow settings,
such as the ECD make-up gas flow,
will
be printed here also.
Apressure figure
is
givenadjacent
to
eachgas, and this value should
be
used when
initially
setting up the chromatograph for operation. These settings
will
ensure proper operation. Once the
detectors andother accessories are operating
normally,
the
gas
flowrates may
be
adjusted for
optimization. The values printed onthis table have been tested with the particular chromatograph
in
the
SRI
quality control laboratory.
Flow equivalences
for eachpressure setting are also
provided foryour convenience. The indicated pressure setting should provide youwith the flow
rate shown toits rightonthe table. Forprecise flowmeasurements, abubble or
digital
flowmeter
should
be
used.
RELAY FUNCTIONS TABLE: Adjacent to the gas flow rate table, you
will
find a relay
functions table that lists each of the eight data system-controlled relays (labeled A through
H)
available
within
the gaschromatograph. Theserelays may
be
operated bymeans of either a timed
event table
within
any of the PeakSimple software programs, ordirectly bykeyboard control.
When using event table control, each relay called inthe event table
will
activate ordeactivate at the
exact same time during each run. This makes these eventtable-eontrolled relays perfect for
operation of solenoids, autosampler injector control, and rotation ofautomated gassampling and
streamselection valves. Adescription of the function of eachrelay
is
printed onthe table. The
default setting for each relay is identified by underlining of the descriptive text. Special purpose
relays, suchas the trap temperature toggle implemented
via
relay B, permit you
to
increase your
trap temperatures from their normal desorption temperature, toabake-out temperature fifty
degrees above the desorb
serpoint,
when performing purge-and-trap analyses.
