1 Introduction
1.1
Product Description
The Archon Purge and Trap AutoSampler is designed to automate the tedious
sample handling procedures associated with purge and trap analysis for volatile
organic compounds (VOC's) under current EPA methods. The Archon can be
used for drinking water, waste water, soil analysis, and solids. The Archon is
designed as a stand-alone unit for retrofit to purge and trap instruments.
The Archon is a state-of-the art robotic, X-Y-Z axis autosampler. The
AutoSampler utilizes a 51 position sample tray that allows water or soil samples
to be run. The tray can be cooled if an optional chiller kit is installed. The Archon
has a unique "gripper" arm which moves the sample vial to different positions that
will bar code read (optional), identify the vial type, stir the sample, equilibrate to
room temperature, and transfer the sample to the water or soil probe position.
When running soil samples, the Archon automates heated purge and trap. The
soil sample may be placed in the patented SoilVial, or if the Archon is setup for
needle sparging, a standard 40 mL VOC vial. A stirring bar (optional) is added,
the cap with a low bleed septum is replaced, and the entire vial placed in the
sample tray. The robotic arm transfers the vial to the vial identification step, and
then lifts the vial into the heated chamber where water is added, with one or both
standards, the sample is then purged directly onto the trap of the concentrator.
If a water sample is to be run, the sample is placed in a 40 mL VOC vial and a stir
bar (optional) is placed in the vial and the vial is placed in the tray. The Archon
robotic arm moves the vial to the vial ID station and then to the probe location
where it is lifted onto the sample probe, and a programmed volume of water is
transferred to the purge vessel. It is during the transfer that one or both of the
standards are added to the sample. It will also drain and clean the needle, sparge
tube, and transfer lines.
The operating modes of the Archon are the Automatic, Manual, and Flush
modes. Automatic mode allows for complete unattended operation. Manual mode
operation allows for single sample operation of the unit, priority sampling, and
running blanks. The Flush mode performs the flushing with hot water and helium
for the cleanup of the system. All modes perform per their programmed method.
The Archon is easily programmed through its own color-coded keypad.
Programming is menu driven and displayed on an LCD screen. Parameters can
be read and altered and the screen displays the function in progress during the
run.
The Archon interfaces directly with the Tekmar LSC 2000, 3000, OI 4460A, 4560
and other purge and trap units.

1.4.3 Interior
Refer to Figure 1-3.
Sample Tray (not shown): A 51 position, all aluminum, sample tray is provided
to hold sample vials. The tray is removable, and when installed, rests on top of
the aluminum tray cooler for cooling the samples.
1. Robotic Arm: The robotic arm is used to move the sample vials. A vial
gripper is used to remove the vials from the tray and place them in the
appropriate sampling positions.
2. Water Probe: The water probe is a patented concentric needle to puncture
water vials, pressurize, and displace water samples to the syringe. After
sampling, the probe is rinsed in a chamber that prevents sample from
spraying onto the instrument components.
3. Soil Probe: The patented soil probe and the Needle Sparge probes
incorporate a "T" fitting design for attachment of water and heated transfer
line. The probe is installed in a heated oven and easily removable for
cleaning or replacement.
4. 26 mL Syringe: A 26 mL syringe is used to move sample, blank, flush and
waste water. The syringe is mounted upright, directly into the valve manifold.
Figure 1-3
5. Standard Valve: The standard injection station uses a 6 port valve with a 1
µL internal loop. The internal standard groove is filled by pressurizing the
standard reservoir and rotating the valve to positions 1 & 2, (Std. 1, Std.
2).Water samples or dilution water passes through the loop to deliver the

standard. Approximately 15 µL of standard solution is flushed during each
cycle.
6. Equilibrium Zone: The Archon utilizes a 5 position temperature Equilibrium
station. If a sample has been cooled or heated, it can be cycled for an
equilibrium time in minutes, prior to analysis.
7. Vial Identification: The equilibrium station also contains the positive vial
identification sensor located in the first position from the left. This sensor
distinguishes between a SoilVial and a standard 40 mL water vial. The
second position contains the optional bar code reader used for sample
tracking.
8. Sample Stir Motor: The Archon allows the sample (both water and solid) to
be stirred. The motor is located below the vial sample stations. The motor
rotates a magnet which will spin a magnetic spin bar placed in the vial. See
Section 7.11 for motor speed adjustment instructions.
9. Overflow Drip Pan: The Archon has a drip pan to collect water in the event
of spillage. The pan has a fitting on the bottom to attach a 1/4" ID hose. Lift
the edge of the Archon and slide the 1/4" ID hose over the fitting. Route the
other end to a drain.
1.5
Vial Types
The Archon may use two different types of sample vials, depending on the
sampling type option installed. The two types of vials are shown below.
Patented SoilVial®
This vial is used if the Archon is purchased with the
SoilVial Option installed. This double-ended vial
contains a frit at the bottom end and vial complies
with USEPA Method 5035.
This vial requires the
use of the low bleed septum (P/N DY-504104-00)
on both ends.
StanStandard 40 mL VOC vial
This is the standard USEPA approved glass vial. It
is used for water samples and for purging soil or
solid samples if the Archon is purchased with the
Needle Sparge option. When this vial is used for
purging a soil or solid sample, you
must
use a
low
bleed septum (P/N DY-504104-00). Figure 1-4
CAUTION
Vial types are NOT interchangeable. NEVER place a SoilVial in a
water vial location and NEVER use a SoilVial if the Archon is
configured with the Needle Sparge Option! Additionally,
permanent markers are recommended for labeling vials. If paper
labels are used, no more than two labels should be applied to
vials for reliable operation.

the cover to be opened.
From the rear of the Archon extend flexible tubing (approximately 60”/1.5M) to be
connected to a blank water reservoir (80 oz./2L bottle) and to a user-supplied
waste receptacle(s). The waste receptacles must be located at or below the
height of the Archon base for proper drainage. Typically, both the blank water
reservoir and waste receptacle are placed on the floor behind the laboratory
bench.

Site Preparation / Installation
03-914642-00:6 2-3
The Archon dimensions are: 21.5W x 17H x 21D inches; 54.6W x 43.2H x 53.3D
centimeters (see Figure 2-1), and weighs approximately 80 lbs./36.5 kilograms.
Figure 2-1
2.5 Gas Connections
Ultra high purity helium (99.999% GC/MS grade) is required for purging soil
samples and operation of the vial gripper arm. The input supply pressure must be
60-90 PSI.
The helium gas line must be connected to the bulkhead fitting labeled “Helium
Input.” Gas line must be 1/8” diameter copper tubing and fittings must be 1/8"
Swagelok®. Use a single, two-stage, high quality pressure regulator with a
stainless steel diaphragm. Consult your supplier for the proper type and size of
cylinder valves. An on-off, shut off valve, should be installed in the line to facilitate
installation. Gas line tubing should be generous. Allow enough length, in a coil, to
be able to move the Archon around to access the rear panel. Tighten and leak
test all connections using propanol and water.
Avoid any pipe thread connections in the supply line. If any fitting requires a
sealant, use an instrument-grade Teflon tape.

2.6 Electrical Connections
The Archon uses a grounded, three-pronged receptacle. Make certain the
electrical voltage is a constant source with no severe drops or spikes in the
voltage. If the power source is not certain, install a power conditioner on the
electrical line. Verify the correct fuse value and voltage selection for the line
voltage to be used.
Attach the power cord to the power receptacle on the rear panel. Check the
power switch located next to the receptacle to be certain it is OFF, plug the power
cord into a three-prong grounded outlet.
2.7 Electronic I/O Signal Connections
2.7.1 Purge and Trap Sync Cable Connector
The Archon communicates with the purge and trap concentrator and GC via a
cable specific to each make and model purge and trap and GC. Section 8 details
the Archon to purge and trap connections. The cable plugs into the 25-pin D
connector located on the rear of the Archon, labeled Remote IO. The other ends
of the cable attach to the purge and trap and the GC. See Section 8 for
installation instructions.
I/O signals vary; some GCs and purge and traps use normally-close contact
closures of active-high TTL logic; others use normally-open contact closures or
active-low TTL logic. Refer to the operator's manual for each system for signal
information.
The Archon signal input configuration must be established to properly receive the
purge and trap's output signals for Standby, Desorb and Stop. “System Settings”
details the parameter configurations for each of the signals. The factory default
setting for each signal is CLOSED.
2.7.2 Personal Computer Connection
The Remote RS-232 port on the Archon rear panel allows connection to external
computing devices. Specific software and cables are required for these
connections. Contact your sales representative for these products.
2.8 Water and Waste Lines Setup
2.8.1 Blank / Wash Bottle Setup
The Archon is supplied with an 80 oz. bottle and lines for the blank, wash, and
dilution water. Remove the bottle from the accessory kit box. The clear line will
attach to the barbed fitting labeled “Helium” and the PEEK line will attach to the
fitting labeled “Water.” See Figure 2-2, The Archon should be supplied with the
same high purity water (free of volatile organic compounds) that is used with the
purge and trap system. Rinse the bottle with purge and trap quality water then fill
it about 2/3 full with DI water. The bottle can be placed either on the bench top or
on the floor behind the Archon.

Remove the rear panel of the Archon and route the bundle of four plastic lines
through the slot in the chassis labeled “Waste Lines.” These waste lines should
empty into the user-supplied receptacles that are placed at a height equal to or
lower than the base of the Archon to provide proper drainage. Note that the
colored waste lines expel excess standard solutions while the clear lines empty
waste water. The user may want to use separate waste containers for the colored
versus clear lines to allow different disposals.
Note: Instructions for two PEEK lines are found on page 2-12.

Sample Tray Setup
Remove the tray from its shipping carton. The tray is installed in the Archon
behind the lower door. Notice the tray has 51 positions and each location is
numbered. Raise the large tray cover and secure the arm lock by gently pushing
it in the center and then lowering the cover. Press the latch button on the top
edge of the lower door and pull the door down.
Grasp the handles on the tray and insert the tray into the Archon with the number
1 position to the front left. The tray will rest on rollers as it is being inserted. Once
the tray is all the way in, it will “lock down” onto four posts. This will align the tray.
Note: The tray must be pushed all the way to the rear most position in the
cabinet.
To remove the tray, lift the front of the tray, then slide the tray out the front on the
rollers.
The tray should be loaded by grouping the vials per the sample method chosen in
Section 5, e.g., water sample vials grouped together and soil sample vials

grouped together. The method parameters, “First Vial - Last Vial”, will determine
what vial numbers are run together.
The Archon vial gripper calibration coordinate settings must now be checked as
factory settings may have changed during shipping, therefore run the
“Calibration Test” procedure as described in Section 6.4.
Note: If any error messages appear while runing the Calibration Test, refer to
Section 9-1. Refer to Section 6.4 for detailed calibration instructions.

Sample Tray Coolant Setup (Optional)
The Archon sample tray can be cooled by an optional, refrigerated chiller bath
(P/N DY-505627-00), and plumbing kit (DY-700085-90) that can be attached to
the coolant coil. It is located inside the cabinet under the tray. The tray rests on
top of the coil allowing conductive transfer of temperatures. See Figure 2-4. The
coolant connections are located on the rear panel at the lower right corner and
are labeled “Tray Coolant, IN - OUT.” The tubing is 3/8" Duro. Refer to the
instructions included with the coolant and plumbing installation kit.
When the sample tray cooler is used, the drip pan drain MUST have a 1/4" ID
hose attached and be routed to a suitable drain. See Section 7.12 for cleaning the
drip pan.

Tools required are: 1/4", 2 ea. 5/16" open end wrenches, small flat blade
screwdriver, 9/64" and 3/32" Allen wrenches, and small needle nose pliers.
The installation of the Archon involves four primary steps. Note: All steps do not
apply to every purge and trap. Installation to each instrument is explained in detail
in later sections.
1. Installation of the four way “cross” fitting in the 2000 and 3000 valve oven.
2. Installation of the Archon heated soil transfer line.
3. Installation of the PEEK tubing for purge gas cut off.
4. Installation of the water transfer line.
The Archon installation kit contains various nuts, ferrules, and fittings shipped in
the smaller carton with the Archon. Examine the contents of the carton to confirm
that all items are correct. Refer to Sections 2.1 through 2.3 for unpacking and
component details.
The installation of the Archon will require the use of two different types of nuts
and ferrules. See Figure 2-5.

this does not allow the Archon to be installed. Therefore, the 3-port fitting must be
replaced with a 4-port cross fitting.
1. Remove the top, left side and valve oven covers from the Tekmar 3000.
2. Using a screwdriver, loosen the screw which secures the thermocouple and
the clamp on the three-port fitting to the cabinet.
3. Using a 1/4" open end wrench, loosen the nuts in all three ports.
4. Loosen the two screws, which secure the sparge tube mount to the cabinet.
5. Pull the sparge tube mount and tubing, out of the 3- port fitting and off the
instrument.
6. Pull each of the other two lines out.
7. Replace the original fitting with the new 4-port cross fitting.
8. Attach all of the lines into the new fitting. Replace the sparge tube, with
mount, back on the cabinet.
Refer to Figure 2-6 for correct line placement in the new fitting.
