Varian Analytical Instrument Warranty
HARDWARE PRODUCTS
All analytical instruments sold by Varian are warranted to be free from defects in material and workmanship for the
periods specified and in accordance with the terms on the face of Varian's quotation or as otherwise agreed upon in
writing between Varian and the Customer. The warranty period begins on the date of shipment from Varian to the
original Customer. However, where installation is paid for by the Customer or included in the purchase price, the
warranty period begins upon completion of installation. If the Customer schedules installation to start later than 30 days
after delivery or if such delay is caused through the Customer's inability to provide adequate facilities or utilities or
through failure to comply with Varian's reasonable pre-installation instructions or through other omissions by Customer,
then the warranty period starts on the 31st day from date of shipment. Moreover Varian will charge the Customer for
labor and other expenses involved in making multiple or follow-up installation service calls.
SOFTWARE PRODUCTS Where software is provided within the frame of a license agreement concluded between the Customer and Varian, any
warranty shall be strictly in accordance with the terms of such agreement.
In the absence of a license agreement and unless an alternate warranty period is agreed upon in writing between Varian
and the Customer, the warranty period is as specified on the face of Varian's quotation. Varian warrants such software
products, if used with and properly installed on Varian hardware or other hardware as specified by Varian to perform as
described in the accompanying Operator's Manual and to be substantially free of those defects which cause failure to
execute respective programming instructions; however, Varian does not warrant uninterrupted or error-free operation.
REMEDIES
The sole and exclusive remedy under hardware warranty shall be repair of instrument malfunctions which in Varian's
opinion are due or traceable to defects in original materials or workmanship or, at Varian's option, replacement of the
respective defective parts, provided that Varian may as an alternative elect to refund an equitable portion of the
purchase price of the instrument or accessory.
Repair or replacement under warranty does not extend the original warranty period.
Repair or replacement under warranty claims shall be made in Varian's sole discretion either by sending a Customer
Support Representative to the site or by authorizing the Customer to return the defective accessory or instrument to
Varian or to send it to a designated service facility. The Customer shall be responsible for loss or damage in transit and
shall prepay shipping cost. Varian will return the accessory or instrument to the Customer prepaid and insured. Claims
for loss or damage in transit shall be filed by the Customer. To correct software operation anomalies, Varian will issue
software revisions where such revisions exist and where, in Varian's opinion, this is the most efficient remedy.

Introduction and Initial Operation
Introduction
Congratulations and thank you for purchasing the Varian, Inc. CP-4900 Micro-G C.
The CP-4900 Micro-GC is a powerful single or dual or quad channel high speed Micro GC
suited for analyses of gaseous samples. This instrument is tailored to meet your needs. The
columns are installed and the instrument as a whole has been thoroughly tested at our factory.
The CP-4900 Micro-GC incorporate technical advancements in Micro electronic gas control
(EGC). The unique advantages of the CP-4900 allow column head pressure settings to become
part of the GC method and can be programmed electronically.
The Varian, Inc. CP-4900 Micro-GC with Micro EGC allows you to optimize your analysis. Apart
from the constant pressure mode, the Micro EGC in the CP-4900 allows you also to program
the pressure over your column. Pressure programming improves not only the speed of the
analysis, but it will give you the opportunity to run new and more extended applications.

Turn power ON
Turn on the CP-4900 Micro-GC using the power switch on the lower front of the
instrument. The “READY” LED should light (after two minutes) when ready. (see
Front_view on page 14).
Factory default states and settings
Your CP-4900 Micro-GC is shipped from the factory with default settings. The following
is relevant information on the factory default states and settings:
• When the CP-4900 Micro-GC is turned on, the power LED will light up and the
system will begin the Flush cycle procedure. The Flush cycle is a 2-minute cycle in
which the various valves are activated and deactivated in order to flush the
entrapped air from the manifold, valves, and tubing.
• After the flush cycle is finished, the method (the default method in this case), which
was last active before the instrument was shutdown, is activated:
• All heated zones will be set at 30°C.
• The Detector filaments will be set to OFF.
If your system is supplied with a DMD (Differential Mobility Detector) detector all
settings are factory installed. The complete DMD method for the instrument (customer)
specific application is tested en installed inside the DMD.

Introduction and Initial Operation
CARRIER GAS CONNECTION
The carrier gas line is connected from a carrier gas connection to the CP-4900 MicroGC at the rear panel CARRIER GAS 1 or 2 port.
Do not use any kind of plastic tubing since air will diffuse through the tubing,
which may cause noisy baselines and decreased sensitivity. The metal
tubing should be clean for GC use. Buy either flamed or chromatographically
clean tubing.
Specifications for the carrier gas used on CP-4900 Micro-GC:
Pressure: 550 ± 10 % (80 ± 10 %)
Purity: 99.995% minimum
Dry and free of particles: CP-Gas Clean filters are recommended
CP-Gas Clean filters are recommended to remove any traces of moisture and oxygen.
For low-level analysis a better grade of carrier gas should be considered. The type of
analysis you want to perform determines the type of carrier gas used. The difference
between the relative thermal conductivity of the carrier gas and the sample components
should be as high as possible. Refer to the table for several relative thermal
conductivities.
Hydrogen 47.1 Ethane 5.8
Helium 37.6 Propane 4.8
Methane 8.9 Argon 4.6
Oxygen 6.8 Carbondioxide 4.4
Nitrogen 6.6 Butane 4.3
Carbon monoxide 6.4
Your CP-4900 Micro-GC is configured either for carrier gas He (or H
is configured for N
(or Ar). Make certain that the carrier gas selection in
2
the controlling Workstation corresponds to the carrier gas connected to
your CP-4900. Use carrier gas corresponding this configuration.
Changing type of carrier gas must only be carried out using the
mandatory procedure in the
Workstation software on page 74
If you are using hydrogen as carrier gas, pay particular attention to
possible leaks at connections inside and outside the CP-4900 Micro-GC
(use an electronic Leak Tester).
CP-Gas Clean filters are filled with nitrogen. If you are not using nitrogen
as the carrier gas, flush filters and gas lines after installation of a new
filter.

SAMPLE GAS
The CP-4900 Micro-GC is an analyzer built for the analysis of gases and vapors only.
You are advised to prepare a non-condensing gaseous samples standard sample for
routine check up of the instrument. Sample pressure should be between 0-100 kPa (015 psi), the temperature between 0 and 40°C ± 5°C of the analyzer ambient
temperature and it must be filtered, preferably through a 5 μm filter. Varian, Inc.
ALWAYS recommends the use of the external filter kit part number CP736729.

Liquids will seriously damage the instrument and should be avoided!
Handling a sample
If possible, filter and dry the sample before introducing it to the Micro-GC. It is advised
to use an External Sample Filter Unit between the injector and the sampling device.
The Filter, male must be hand tightened into the Filter Female, followed by a 1/8th turn
with a 7/16" wrench. The arrow on the Filter Female should be directed towards the
Fingertight Fitting.
Whenever possible remove moisture from samples introduced to the
CP-4900 Micro-GC.
