Installation Checklist
The 7683 Automatic Liquid Sampler consists of the G2612A ALS Interface Board,
the G2613A Injector Module, the optional G2614A Tray, and an optional G1926A
Bar Code Reader for the tray. The tray and ALS interface board are installed only
on the 6890 Plus Gas Chromatograph (GC).
Use this checklist when installing your 7683 Automatic Liquid Sampler and
accessories.
❐Unpack the sampler components.
❒Install the ALS Interface Board, if purchased.
❒Install the tray, if purchased. See page 2.
❒Install the injector mounting post. See page 4.
❒Install the injector. See page 4.
❒Install the (8 sample position) turret, if desired. See page 17.
❒Install the bar code reader, if purchased. See page 6.
❒Connect the cables. See page 8.
❒When using the injector for cool on-column injection:
a. Check that the correct needle support assembly is installed. See
page 11.
b. Install the proper syringe for your column. See your Operation Guide.
❒Configure your GC. See page 12.
❒Test the installation by performing a trial run. See page 13.

Installing the G2614A Tray
If you purchased Agilent accessory G2612A separately from your 6890 Plus GC,
install it now. Refer to the documentation provided with the accessory for
instructions. After it is installed, continue with the steps below to install the
optional G2614A Tray.
1. Unpack the injector module, tray, and bar code reader and place them on
the bench top.
2. Remove the 3 injection port cover Torx screws shown.

Caution Do not move or manipulate the robotic arm or gripper. Moving the arm or gripper
back and forth can cause damage. If necessary, rotate the arm assembly a few
degrees until there is enough clearance.
3. Align the tray over the 3 holes in the injection port cover and locate in place.
Tighten the captive screw in the center of the tray mounting arm to hold the
tray in place. Install the 2 mounting screws into the tray and tighten until
the tray is secure.
4. Install the tray quadrants. Slide the leading edge of each quadrant under the
guides on the tray, then snap the front tab into the slot on the tray. See
Figure 2.

Installing the G2613A Injector
Note Do not mount the G2613A Injector on a mounting post for a 7673 Injector.
Remove the old post and replace it with the new one.
1. Install the mounting post on the injection port cover in the front or rear
location, as desired.
2. Open the injector door. Slide the packing material and syringe carriage
down, then remove the packing.
3. Mount the injector. Line up the hole in the base of the injector that is nearest
the cable with the mounting post. Lower the injector about an inch (2. cm)
onto the post.

4. Front location:
Turn the injector so that the turret is facing the front of the GC. Lower the
injector until the alignment pin in the base enters the alignment hole in the
injection port cover.
Back location:
Turn the injector so the turret faces the left side of the GC. Lower the injector
until the alignment pin in the base enters the alignment hole in the injection
port cover.
. Check your work:
• The injector must be vertical.
• The alignment pin must be properly seated in the alignment hole.
• The injector feet should touch the injection port cover.
If the injector will not sit upright on the GC, check that the plumbing and
cabling under the injection port cover are properly routed in their channels.
Choosing the turret type to use
Your G2613A Injector comes with 2 types of turrets, a standard turret for use
with or without a tray, and an alternate 8 sample position turret which is used
without a tray. If you are using the optional G2614A Tray, the injector comes pre-
configured with the proper turret type.
If you are not using a tray, you may use 1 to 3 sample vials in the standard turret.
If you wish to use up to 8 sample vials, you may remove the standard turret and
install the alternate 8 sample position turret. See Removing The Turret for
details.
Note After changing turrets, it is recommended that you perform the turret alignment
procedure described on page 17.

4. Slide the support bracket towards or away from the tray until the top of the
bar code reader is parallel with the tray surface. Tighten the mounting
screws.
. Adjust the Bar Code Reader’s height. Slightly loosen the height adjustment
screw on the side of the support bracket and raise or lower the bracket until
there is a very small gap—about the thickness of a piece of paper—between
the mounting clips on the bar code reader and the tray. See Figure 4. Tighten
the height adjustment screw.

Adapting For Cool On-column Injection
10
A apting For Cool On-column Injection
The 7683 Automatic Liquid Sampler can be adapted to inject samples directly
onto 2 0-µm, 320-µm, and 30-µm columns in the 6890 with cool-on-column inlet.
If you wish to adapt the injector and GC for cool on-column use, follow these
steps:
1. Select the on-column syringe needed for the column size. See your Agilent
catalog for consumables and supplies, and Volume 2 of your GC Operating
Manual for a list of parts.
2. Prepare the GC inlet. (See Volume 2 of your GC Operating Manual for
instructions).
• Check your needle to column size.
• Verify that the insert matches the needle size.
• If necessary, replace the septum.
3. Verify that the correct needle support assembly is installed in the injector.
Replace if necessary. See Replacing The Needle Support Assembly on
page 19.
For a list of consumables needed to perform these injections, see Volume 2 of
your GC Operating Manual.

Configuring Your GC (6890)
When installation is complete, configure your 6890 GC for use with the 7683
Automatic Liquid Sampler.
Refer to the section on injector configuration in your GC Operating Manual for
instructions to set the following:
• Front and/or back injector location
• Nanoliter enable
• Tray enable
• Bar code reader position (position 3, enable, and type)
• Solvent B bottle usage (vial B only, or alternate between vials B and B2)

Making A Trial Run
Once installation and configuration are complete, make a quick injection using
the sampler to verify that it works properly.
1. Install an empty syringe in the injector.
2. Place empty bottles in the Solvent A and Waste A turret positions. Place an
empty capped sample vial in the tray 1 position (or the turret sample 1
position, if not using the tray).
3. Set the following parameters on the GC:
4. Set the GC oven program to 2 °C with a 0°C/min ramp, a hold time of
0.1 minutes, an equilibrium time of 0.3 minutes, and an initial time of
0.3 minutes.

Maintenance
15
Maintenance
This section contains some suggestions for ensuring good performance of your
7683. The maintenance interval varies with the use of the instrument.
Caution Do not use any lubricants on the 7683 Automatic Liquid Sampler. They may effect
the chemical performance of the GC and damage the instrument.
On an occasional basis:
❒Clean the surface of the tray arm, gripper, gripper jaws, and tray quadrants.
❒Clean the needle guide and nearby surfaces of the injector. Dust and dirt
accumulate in these areas and can be picked up by the syringe needle and
carried into the inlet.
❒Clean the surface of the injector. Vacuum off any dust that builds up around
the vents.
❒Make sure the injector mounting post is tight.
❒Make sure the tray mounting screws are tight.
❒Make sure the knurled nut on the top of the turret is tight.
❒Be sure all the cables are securely attached.

Installation Guide
Removing The Turret
16
Removing The Turret
If you need to remove or replace your turret, use the following instructions for
proper replacement.
1. For a 6890 GC with a tray only:
• Disable the tray if you are changing from the three sample position
turret to an eight sample position turret.
• Enable the tray if you are changing from an eight position turret to a
three sample position turret.
2. Disconnect the injector cable from the GC.
3. Open the injector door. Unscrew and remove the knurled nut from the top
of the turret. See Figure 10.
4. Rotate the turret so that the open section faces the back of the tower and
the arrow on top of the turret points directly back (see Figure 10). Push the
stripper arm toward the back, then lift the turret up so that it clears the
center shaft.
. To install the replacement turret, align the tab on the motor hub with the
slot in the underside of the turret.
6. Push the stripper arm to the back of the tower, insert the turret with the
open section facing the back of the tower and the arrow pointing back, and
install the turret with the tab seated in the slot. Seat the turret on the hub,
rotating it gently if necessary until it drops completely into position. The top
of the threaded shaft should be almost level with the top of the turret.
7. Replace the knurled nut and tighten it firmly (finger-tight).
8. Close the injector door.
9. Plug the injector cable into the GC.
10. Turn the GC off, then on, and check for the Ready light on the injector.
