AQUATRAN Model 3/40 Operator’s Manual Introduction
MOCON, Inc. Revision D 1-3
Measuring a Water Vapor Transmission Rate
To make an accurate transmission rate measurement a known concentration Test Gas is applied to one
side of the barrier material to be tested and the other side is swept with a water vapor free Carrier Gas
(nitrogen). This process is illustrated in Figure 1-2 which depicts a package mounted in a Diffusion Cell
designed for a Cup or Tray.
As shown in the illustration the package is mounted between the parts of the Diffusion Cell. The sealing
surfaces and O-rings in the cell prevent outside moisture from affecting the measurement.
The Test Gas side of the sample is exposed to the controlled environment in the Test Chamber. The
environment in the Test Chamber is maintained at a constant relative humidity.
The Carrier Gas (Nitrogen) enters the interior of the sealed package (carrier side). As water molecule
permeates the sample barrier it mixes with the Carrier Gas. The output side (exhaust) of the diffusion cell is
routed to the water vapor sensor. The amount of water vapor in the carrier gas is measured using the
patented Modulated infrared sensor.
Seal leakage in the diffusion cell can be a significant source of error when measuring the transmission rate
of a sample. The TruSeal™ flush ring at the perimeter of the cell minimizes the effect of ambient moisture
on the measurement. During a test the TruSeal™ flush ring is purged with carrier gas minimizing the
possibility of leakage past (or permeation through) the seals.
The AQUATRAN Model 3/40 can use a generated RH for the Test Gas. The RH of the Test Gas can be
from 30% to 90% RH for a Model L. Different test cell configuration will be required for testing 100%RH
verses generated RH.

Introduction AQUATRAN Model 3/40 Operator’s Manual
1-4 Revision D MOCON, Inc.
Testing Packages and Films
To test packages (or films) the sample must be mounted in a Diffusion Cell. A Diffusion Cell exposes one
side of the sample barrier to a Test Gas and the other side to a Carrier Gas. The gases supplied to the cell
can be dry or at a specified RH.
The Diffusion Cells used in the AQUATRAN Model 3/40 expose the Test Gas side of the sample barrier to
the controlled environment in the Test Chamber. A Compressed Air supply is used to maintain the
environment in the Test Chamber at a constant water vapor concentration (20.9%) and Relative Humidity.
The design of an effective Diffusion Cell must accommodate the physical characteristics of the sample to be
tested. A Diffusion Cell design optimized for testing small cups may not be suitable for testing large trays.
The Test Chamber in the AQUATRAN Model 3/40 contains positions for four removable Diffusion Cells.
These removable Diffusion Cells are referred to as Test Cartridges. To accommodate most testing
requirements MOCON offers a selection of Test Cartridges. The designs of these Test Cartridges are
optimized for different types of samples (bottles, trays, pouches, bags, cups, and films).
To test packages the sample must be mounted in an appropriate Test Cartridge. After the sample is
mounted in a Test Cartridge, it is installed and clamped into one of the four positions in the Test Chamber.
The four positions in the Test Chamber are referred to as Test Cells. The method used to mount the sample
in the Test Cartridge is dependent on the design of the cartridge and the sample. For more information on
mounting packages see the information supplied with your Test Cartridges. See Figure 1-3, 1-4 and 1-5 for
examples of some of the Test Cartridges that are available. For more information on testing packages see
Chapter 6.
To test a film sample, it is prepared and mounted in a Film Test Cartridge. After the sample is mounted, it is
installed and clamped into one of the positions in the Test Chamber. See Figure 1-6 for an illustration of the
Film Test Cartridge. For more information on mounting and testing Film Samples see Chapter 7.

Permeation Test Overview
A “Permeation Test” consists of up to two phases that are performed using a Test Cell. The “Cell” may
contain a package cartridge or a film cartridge. The Test Phase (always present) is used to measure the
transmission rate of the test sample. The Individual Zero Phase is optional and may occur at the beginning
or end of a Permeation Test. Each phase in the test consists of a series of discrete states. A Permeation
Test may utilize all or only a subset of the possible test states. During a test the steps (or states) within each
phase are executed in a fixed order. This order is called the “Test Sequence”. A brief description of the
phases and states within a permeation test are given below:
Individual Zero Phase
An Individual Zero Phase is used to determine the amount of water vapor that is present in the carrier gas
from factors other than actual transmission through the sample. The Individual Zero value is used to correct
the transmission rate values obtained from each sample during testing. For more information on when and
how to use an Individual Zero Phase see “Individual Zero Processing” in Chapter 3.
Conditioning the Sample
Almost every material requires a period of time to acclimate to the test environment and reach equilibrium.
A conditioning state can be specified to allow the barrier to “Condition” to the test environment. When used,
the Conditioning State will occur at the beginning of each test phase. See details in Chapter 3.
ReZero State
Periodically the instrument baseline must be measured so that any changes in the baseline will not affect
the accuracy of your transmission rate data. This is done during a “ReZero State” by measuring the
apparent Water Vapor Transmission Rate of the ReZero Cell.
Cell Examination State
The Cell Examination State is used to measure the transmission rate of the barrier sample. The carrier gas
leaving the Test Cell is sent to the water vapor sensor where the amount of water vapor contained in the
gas is measured to determine a transmission rate.
Bypass State
When no gas is being routed to the water vapor sensor it is said to be in the Bypass State. The Bypass
State is used to maximize the useful life of the sensor. The water vapor sensor is automatically placed in
Bypass during conditioning, when tests are completed or when an excessively high level of water vapor is
detected.
Test Completion
At some point sufficient measurements will have been made to accurately determine the transmission rate
of the samples. A Permeation Test can be terminated manually by the user, after a fixed number of test
cycles or using an automatic convergence process. When testing is complete, the cell is removed from the
test sequence and no further transmission rate examination of that sample is performed. For more
information on stopping a transmission rate test see “Determining When to Stop a Test” in Chapter 3.
Report Generation
You can request a report for one or all cells at any time until a new permeation test is started. See the
instrument Help System for information on printing reports.

Carrier Gas (Nitrogen)
The AQUATRAN Model 3/40 requires a Carrier Gas that is 99.7% nitrogen.
Compressed Air Supply
The AQUATRAN Model 3/40 requires a supply of clean, dry compressed air for chamber RH generator that
provide moisture as test gas. The supply pressure must be between 72 and 95 psig (5 to 6.55 Bar) at a
maximum flow rate of 0.88 CFM (25 LPM). The compressed air purity must meet or exceed ISO 8753-
1:2010 [1:3:1]. Each instrument requires a local compressed air regulator. A compressed air regulator is not
supplied with the instrument.
Gas Distribution System
Each instrument ships with a local regulator/isolation device (called a Regulator Tee) that can be used to
connect the instrument to a common Carrier Gas distribution system. Figure 2-4 illustrates how a gas
distribution system for multiple instruments can be created using the provided Regulator Tee.
When using a compressed gas cylinder, consideration should be given to the impact cylinder replacement
will have on operational efficiency. Interruptions to the gas supply when a cylinder is changed (or goes
empty) will have an adverse effect on any active tests. Cylinder manifolds that provide an uninterrupted gas
supply during cylinder replacement are available from many gas suppliers.
