CP-8400 AutoSampler & CP-8410 AutoInjector 1
Introduction
We strongly recommend that you read the entire manual before you start
using your CP-8400 AutoSampler or CP-8410 AutoInjector. The
CP-3800 will sense whether you have a CP-8400 or CP-8410 installed
automatically and will sense if the Auto Sampler is set to perform liquid
sampling with a syringe or SPME sampling. You will be presented with
the appropriate screens and limits for the specific Auto Sampler and
sampling mode configured on powering up the GC and Auto Sampler.
The CP-8400 is a 100 vial capacity AutoSampler designed to be used
with the CP-3800 GC. The CP-8410 is an AutoInjector based on the
CP-8400; it has a manually positioned tray and can accommodate up to
10, 6, and 5 each of 2 mL, 5 mL and 10 mL vials, respectively. Both the
AutoSampler and AutoInjector can inject into up to two injectors; the
injection may be made into either one or the other of the injectors or into
both (either from the same vial or from adjacent vials) during the same
run. You may select to sample just before injecting or you may choose to
have the Auto Sampler prepare the next injection before the current run
ends (Prep Ahead). Both the CP-8400 and CP-8410 are
preprogrammed with several injection modes (Standard On-Column,
Standard Split/Splitless, Viscous, Volatile, and Neat) that are optimized
for most common types of samples. The User Defined mode allows
access to all parameters and should be used with discretion since
injection accuracy and precision may be adversely affected by incorrect
choice of certain parameters. The SPME mode requires different
hardware (optional) and is selected through a switch on the Auto
Sampler’s syringe carriage. If the SPME mode is selected the other
injection modes will not be presented to you.
Once your CP-8400 or CP-8410 is installed and calibrated, you may
begin running immediately. To perform a single injection, complete the
following steps:
1. Press the green Start button located at the upper left corner of the
CP-3800 keypad.
2. Enter the vial number, number of replicate injections, the injection
volume, and which injector you wish to use.
3. Press the AutoInject softkey.

2 03-914852-00:4
Your AutoSampler or AutoInjector will execute the desired injection.
To set up an automated series of injections, simply complete the
following steps:
1. Press the Automation Select/Edit button on the CP-3800, choose
either Single Method automation to run all of your samples with a
single method, or choose Method Sequence Automation to run
specific methods with specific vials.
2. Press the Automation Select/Edit button again and press 2to
select Single Method, or 3to select Method Sequence and enter
the methods you wish to use, the vial range, the amount you
want to inject and the injector you wish to use (if you have more
than one injector installed).
3. Place your samples into the AutoSampler carrousel.
4. Press the Start button.
This manual will cover AutoSampler installation, software setup and
calibration to the correct sampling and injection positions, a description
of the operating parameters, and some examples of how you may wish
to use the CP-8400/8410 to accomplish your analyses. If, after reading
this manual you still have questions or encounter a problem that is not
covered, please contact Technical Support for further assistance.

Installing the CP-8400/8410
To use the CP-8400 with the CP-3800 Gas Chromatograph, your
CP-3800 must have Version 3.2 or later software installed. The CP-8410
requires version 3.3 or later. To use SPME mode sample introduction
with either the CP-8400 or CP-8410 you must have Version 3.3.5 or later
software installed. To check the software version installed in your GC,
press the Status key on the GC keyboard, press the Enter key to show
instrument status, and then press the Software Version softkey. The
software version will be shown on the CP-3800 display. If your GC was
manufactured before October 1999 and you have two or more injectors
installed, you will need to schedule a service call with your Varian
Technical Support Representative to have the injector positions
relocated so that the CP-8400 can effectively use them.

Input current max. 1A
Environmental Conditions

Relative humidity 0 to 95%
Before installing the CP-8400 or CP-8410, make certain your CP-3800 is
equipped with the appropriate top cover. This cover will have a long
rectangular opening for the installation of the injector locator plate,
markings indicating the front and rear installation positions for the
AutoSampler, and a small rectangular opening to route the
CP-8400/8410 power/communication cable through.
There are two positions on the CP-3800 in which the CP-8400/8410 may
be installed: front and rear. The front position allows the CP-8400/8410
to use the front and middle injectors. The rear position allows the
CP-8400/8410 to use the middle and rear injectors. The CP-8400/8410 is
aligned to the top cover of the CP-3800 by a pair of pins protruding from
the bottom of the AutoSampler/AutoInjector base. These pins will fit into
holes on the top cover. The base is secured to the top cover via two
screws at the rear and three screws underneath the AutoSampler
carrousel/AutoInjector sample tray. The figures that accompany this
description depict a CP-8400 AutoSampler. They apply equally to both
the CP-8400 and CP-8410.

CP-8400/8410 CP-3800 Top Cover
To install the CP-8400/8410, follow the steps below:
WARNING:
SHOCK HAZARD
Dangerous voltage exposed. Turn the CP-3800 GC power off. Failure to do
so may result in accidental contact with dangerous voltage.
1. Power down the GC and any other attached devices. Remove
any old equipment or old autosamplers from the top of the GC.
Place the CP-8400/8410 near the GC, manually rotate the
Injector tower so that it does not obstruct the carrousel.
2. Remove the old CP-3800 top cover by lifting up and removing
the Detector cover; set it aside in a location that is out of the
way. Remove the left side top cover by lifting the rear of the
cover and sliding it towards the rear of the GC and up. Remove
the 4 screws holding the injector cover down on the top of the
GC. Retain the screws and set the old top cover aside.
3. Locate the CP-8400/8410 power/communication cable and the
CP-8400/ CP-3800 top cover. Route the single D-shell connector
through the hole from the bottom of the cover to the top so that
the single D-shell is available from the top of the cover. Route
the power cable and CP-3800 25 pin D-shell connector across
the top of the GC to the left side of the GC. Plug the power cable
into Aux 1 (J46) and the 25-pin D-shell into the S.I.D. 1 (J4)
connector.

4. If the Injector locator plate is installed in the top cover, remove it
by removing the two screws located on either end of the locator
plate. Install the top cover so that the pins on the top cover fit
into the corresponding slots on the CP-3800 chassis. Screw the
top cover in place.
5. Install the Injector locator plate by fitting the circular holes over
the injectors. You may need to push the locator plate just a little
bit in order to get the injectors to fit. Do not use excessive force.
If the injectors do not fit conveniently, loosen the screws holding
the injector(s) to the CP-3800 chassis and adjust the injector(s)
positions so that they conveniently fit into the locator plate. The
top cover has small access holes to allow you to loosen the
retaining screws on the injectors. You may need to unscrew the
injector nut and remove the inject switch to have unimpeded
access to the injector retaining screws; replace the injector nut (if
removed) so that you have proper alignment when the locator
plate is installed. Once the injector(s) are properly aligned, screw
down the alignment plate and then screw down the injector
retaining screws. Remove the locator plate, replace the inject
switch on each of the injector(s) and reinstall the locator plate.
6. Place the CP-8400/8410 onto the top cover, aligning it with either
the front or rear mounting position as appropriate. Locate and
install the two small screws provided with your CP-8400/8410
and screw down the rear tab.
7. Locate the three long screws and install in appropriate screw
location under the carrousel (note that the CP-8410 does not
have the rollers or central hub but will have the same screw
locations).

8. Plug the D-shell connector of the power/communications cable
into the CP-8400/8410.
9. Remove protective shipping materials from the injector carriage
and install the syringe into the AutoSampler injector tower by
opening the clear plastic door, carefully inserting the syringe into
its holder and the needle through its guide, then fasten the
plunger screw on the top and snap the retaining clip over the
syringe.
