1.0 INTRODUCTION
The Model M8700 Package Oxygen Permeation Analyser has been designed to provide accurate
and uncomplicated measurements of oxygen transmission rates (OTR) through bottles and
packages. The instrument displays the test OTR result in cc/package/day. The Model 8701
instrument is available to measure bottles, various types of packages and uses various adapters
which may be fitted to the instrument to carry out these tests.
The M8700 is unique in its ability to test up to 11 samples simultaneously; with individual testing
regimes controlled by the Systech M8700 software.
The M8700 can be calibrated to certified gas or package.
This manual is arranged in a manner we feel will provide the greatest ease of reference and use.
We are proud of our active program of research and development. If you encounter any
difficulties, we would like to hear about them.
1.1 BRAND

2.0 PRINCIPLE OF OPERATION
The 8700 incorporates our proprietary, coulometric, oxygen sensor to detect oxygen transmission
rates through all types of bottles or packages. Bottles / packages are fitted onto their respective
adaptor using a fast-setting epoxy adhesive (3-5 minutes setting time).
An oxygen-free (99.999% zero grade N2) carrier gas flows through the bottle.
Molecules of oxygen diffusing through the walls of the bottle are conveyed to the sensor by the
carrier gas.
This allows a direct measurement of the oxygen without using complex extrapolations. The
oxygen transmission rate of the bottle is displayed as cc/package/day.

3.0 INSTALLATION
3.1 VOLTAGE INPUT/FUSE CARTRIDGE
The power entry module is on the back of the instrument it not only allows attachment of the
power cord, but also contains the fuses. Supply voltage is 90-260 VAC, 50-60Hz.
Note that the cartridge contains two fuses. Both fuses must be installed to ensure proper
operation of the instrument. The fuses are rated 5A @ 250V and are a slow-blow type. Replace
only with fuses of equivalent ratings.
3.2 CONNECTING GAS LINES
The user must supply oxygen-free (99.999% zero grade) nitrogen to the instrument. Systech
Instruments provides an oxygen trap with the analyser to remove traces of oxygen from the
nitrogen.
NOTE: The inlet pressure must be set between 4.0 and 6.0 bar gauge. If the supply
pressure is not within this range, then flow through the instrument will be at the
wrong level, resulting in erroneous measurements.
On the back panel are the gas, power and communications connections. The 9-pin D-type
connector is for the communications and the power is via a standard IEC socket.
There is an inlet fitting for N2(nitrogen) labelled N2In 5 Barg, an inlet fitting for CAL (calibration)
labelled Cal Gas In. There are also two outlet fittings marked as N2VENT1 and N2VENT2 (8mm
OD tube connection). The inlet and outlet fittings are 1/8" Swagelok® type, except for the N2
VENT2.
The oxygen-free nitrogen is connected to the N2IN fitting. Do not over tighten the nuts when
connecting the gas lines. It is recommended that the input gas lines are purged prior to being
tightened up at the instrument connections. This will reduce the amount of air that is present in
the pipes.
There is no need to connect tubing to the vent lines. It is vital for the correct running of the
instrument that these vents are not compromised in any way.
When instrument is not connected to a nitrogen source, the N2IN fitting should be sealed with the
provided blanking cap to prevent saturation of the oxygen trap (the cylindrical object in the photo
below).

3.3 INSTALLATION OF COMM PORTS CONTROLLER
Note: This is required for some computer systems which either do not have an RS232 comms
port fitted or where the existing comms port is already in use.
Install the COM port controller board (or USB –RS232 adaptor) according to the manual shipped
with the controller / adaptor.
Make sure that COM ports have assigned numbers from COM 2 (if there is one RS232 port in
your PC) or from COM 3 (if there are two RS232 ports in your PC).
If they are not assigned to these figures, reassign the COM ports through the computers “Control
Panel –System - Hardware - Device Manager –COM ports”. If in any doubt, contact your IT
department or Systech Customer Service Department.
The Model 8700 Analyser software will look for installed units on COM ports 1 to 6.
It should be noted that some USB to Serial RS232 adaptors will not work, and others give
intermittent results. Therefore, we recommend using only USB to Serial adaptors obtained from
Systech Illinois.

5.0 BASE LINE AND SYSTEM CALIBRATION
5.1 BASE LINE
Connect power and nitrogen to the instrument complying with the earlier instructions and turn on
the power switch.
Note: A base line check should be carried out when first commissioning the instrument, or after a
period without use. The baseline should be re-established every 2 - 3 months or before testing a
very high barrier package.
With the Model 8700 switched on, double click the 8700 program icon if you have installed a
shortcut, otherwise select it from the program menu. The main menu screen will appear as shown
or like that shown below:
Note that the product images show both 8700 and 8701 variants. This is because both instrument
constructions share the same PC software.

Click the “BASE LINE”button.
The following “‘BASE LINE’ STARTER” screen will appear.
Click on a ‘COM’ port button with a green square next to it, where an installed unit is found that is
not in use. The ‘baseline screen’ will appear as shown below:
For the commissioning of a new instrument it will take a considerable length of time to establish a
true low value of the base line. A base line should be run for at least three days. The base line
value will fall from a relatively high ppm value to fractions of a ppm. The best way to judge
whether the value is coming to an equilibrium is to repeat base line tests. Enter a value of say 30
minutes into the PURGE TIME box, complete the base line test as shown below and repeat the
test with longer durations, enabling a graph that can show a true equilibrium.

11
Click the “START” button to begin a baseline.
Click the ‘YES’ button to confirm.
When the BASE LINE routine is started, nitrogen flows through the instrument to evacuate any
residual oxygen. The flow is automatically set to high. The gas will bypass the sensor for a time
equal to the PURGE TIME parameter set by the user, the bar located beneath PURGE MFC
indicates the percentage of purging completed (see diagram below).

Model 8700 Operator’s Manual v2.9
www.systechillinois.com
Page
12
When the PURGE TIME is within the last minute of purging the progress bar will turn yellow and
the flow rate is adjusted automatically and controlled to 10 cc/min.
After the PURGE TIME expires, then the BASE LINE process begins. The O2ppm will now be
plotted in 1-minute intervals on the graph. The O2value will change on the graph as the value
approaches equilibrium and becomes stabilised.
When the base line has reached equilibrium, click the “BASE LINE NOW”button to set the BASE
LINE for the instrument.
Note: in the above example the base line has not run for long enough to be fully stabilised.
Analysis of the graph above shows that it has taken approximately 100 minutes for the ppm value
to fall from 1ppm to zero. However if the base line is run again the graph will start at a level of
say 0.2ppm and it will be easy to judge over a larger scale that it is at equilibrium.

13
A window will appear asking the user to confirm the BASE LINE.
Click “YES” and the instrument now has a re-established BASE LINE.
At this point, the user may either click the STOP button or allow the BASE LINE to continue in
order to verify the result has stabilised.
Clicking the BASE LINE AGAIN button will do a second BASE LINE. Clicking the STOP button
ends the BASE LINE routine.
To exit the BASE LINE window, close the window by clicking on the “X” in the upper right corner.

5.2 HISTORY OF BASELINE
The history of baseline data (and calibration data) is saved under a directory called “8700
maintenance files”. This directory is created when the software is first installed and is saved on
the ‘C’ drive. It is important to review this information from time to time as it can indicate the
variation of the base line over time.
Open the file “base.txt” and a list of baseline history will be shown.

5.3 SYSTEM CALIBRATION
The Model 8700 is calibrated at the factory prior to delivery. It is not necessary to perform a
calibration during commissioning of the instrument but a calibration check is recommended every
9 –12 months. When it becomes necessary to calibrate the instrument a package or a calibration
gas can be used.
View of the 8700 Platen
5.4 PREPARATION FOR CALIBRATION
5.4.1 Package Calibration
Calibration of the instrument to a package would not normally be practical because packages of
known OTR are unusual.
For a package calibration a package of known OTR must be glued on to Station 0, (older
instruments MASTER)
Attach the package following the instructions in section 6.2.
5.4.2 Gas calibration
For gas calibration the calibration gases may be obtained from a reputable special gases
supplier. It is recommended that a certified cylinder of approximately 20ppm O2 in Nitrogen be
obtained. It will come with a certificate showing the actual measured value. Connect this cylinder
with a good quality regulator to the instrument at a pressure of 5 Bar, taking care to purge the
regulator and the connecting pipes first.

5.5 STARTING THE CALIBRATION
NOTE: For gas calibration only, make sure you position the valve (CALIBRATE/NORMAL)
at the rear of the instrument to the CALIBRATE position.
Double click the 8700 program icon to start the software. At the main menu, click on the
CALIBRATE button. “’CAL’STARTER” screen will appear as shown below.
Click on the COM port button corresponding to the unit to be calibrated (ensure there is a green
square next to it) and the Calibration screen will appear as shown below.
The top half of the ‘Calibration’ window consists of setup parameters and status indicators. The
bottom half displays a real time graph during the calibration process.
First click the GAS or PACKAGE button in the CALIBRATION TARGET area.

For GAS calibration enter the ppm value of the calibration gas in the O2 (ppm) box; for
PACKAGE calibration enter the OTR value of the package in the OTR box.
Enter the purge time in the box in the PURGE MONITOR area; a suggested time would be 30
minutes.
Clicking the “START” button will begin a calibration cycle.
Confirm the start by clicking “YES”.
When the Calibration routine is started, nitrogen flows through the instrument to purge any
residual oxygen. The flow is set automatically. The gas will bypass the sensor for a time equal to
the PURGE TIME parameter set by the user. The Purge Progress Bar located next to the Purge
Time indicates the percentage of purging completed.
When the PURGE TIME is within the last minute of purging the progress bar will turn yellow and
the flow rate is adjusted automatically and controlled to 10 cc/min.
