Upon receiving the chromatograph and data system from the freight carrier, immediately
inspect the containers for visible signs of damage. Ifany external damage is observed, notify
the delivery person immediately. If no external signs of damage are present, proceed
to
inspect
the contents of the containers.
If
the materials appear
to
have been damaged
in
shipping,
immediately contact the carrier and submit a written report describing the extent of the damage.
All packing materials and containers should
be
retained
if
damage is discovered until the carrier
has been able to inspect the damaged goods,
If
no damage is discovered, packing should be
retained until proper unit operation
has
been established. The chromatograph, serial data
interface cable andmanual are shipped
in
onecontainer, along
with
theGCaccessory kit. This
container is a reusable plastic shipping container. These containers are rugged and shipped
easily
via
freight
carriers. Most
importantly,
the plastic container protects larger, more complex
and delicate instruments from costly damage to external accessories. Save the packing materials
after removing the chromatograph, for future transportation.
The contents of the containers should
be
checked against the packing slip accompanying
the shipment Verify that
all
specified accessory items ordered such as columns, syringes and
the
like
have actually been shipped.
If
any items have been omitted or are missing from the
shipment, contact SRI Instruments for location and/or replacement of the item.
The SRI model 8610C gas chromatograph requires either 110 VAC at 60 Hertz or 220
VAC at 50 Hertz, dependent on which AC power supply was specified when ordered. Both AC
power supplies support the 3-prong grounded outlet. Proper grounding is required to minimize
AC line interference and eliminate ground loops. The 220 VAC plug is keyed so that it cannot
be inserted into a 110 VAC receptacle. A generator or high-eurrent inverter may
be
used for
operation from a vehicular power source.
If
an AC power generator
is
used, as is done in the
field, line voltage and/or current may fluctuate. Appropriate steps should
be
taken to
minimize
any inconveniences caused by line noise or an irregular ACwavefonn.
A standard model 86lOC gas chromatograph measures approximately 18.5" x 14.5" x
12.5" and requires a counter surface space of about 32" x 22". Eight inches ofclearance are
needed
in
front of the left side control panel for the fan,
gas
line access and the AC power
switch. Another six inches of clearance are suggested in front of the right control panel and
to
the rear of the unit for safe operation and ease of access during routine service. The red oven
cover requires a clearance ofat least 24" (measured from the counter top) in order to provide
adequate access to the column oven for service. If the chromatograph is equipped with optional
accessories such as the 10 station purge and trap autosampler for the optional built-in EPA Style
purge and trap, the access to the left side of the chromatograph must
be
increased by a
minimum of an additional 12". The compact footprint of the system is economical on lab
counter space and is ideal for mobile environmental installations.
Prior to placing the chromatograph into service, the gas supply and related plumbing
should
be
installed and routed. The gas cylinders should
be
located outside the lab where
possible, with only the lines plumbed inside to the chromatograph, Gas cylinders should be
secured in place with chain or nylon strap to prevent a cylinder from falling and snapping off
the valve. A
gas
cylinder contains
up
10
2700psi and canbecome a deadly projectile
if
the valve
stem were
snapped
off. A regulator should be used to set the supply a gas pressure reduced to a
value appropriate for introduction into the Gc.
Gas
pressures at each cylinder pressure
regulator should be maintained reasonably above the carrier gas regulator setting
in
order to
provide a range of control (a supply pressure set to no more than 20psi greater than the EPC
setpoint is recommended). A block valve should
be
inserted on the output side of the regulator
to permit line service when needed, and to permit immediate shut-off
in
case of emergency.
