General Safety Considerations
The following safety items must be observed to avoid personal injury and to prevent
damage to the ta7000F Monitor. All personnel involved in installation, operation or
service of the ta7000F should be thoroughly familiar with these items. These consider-
ations are in addition to all site specic safety procedures.
Hydrogen (H2) Gas Flow
Since Hydrogen is ammable and can be explosive if conned, do not operate
Flame Ionization Detection (FID) equipped instruments without an external
shut-o valve on the hydrogen line. Periodically check that the shut-o valve
operates correctly when the FID ame goes out.
Also, in FID-equipped instruments do not provide hydrogen ow unless carrier
gas is also owing. In any application using hydrogen, be sure to turn O the
supply at its source when removing any portion of the H2ow path or per-
forming service procedures, etc. Should gas ow measurements through an
FID be required, do not measure air and H2together. They should be measured
separately to minimize explosion hazard.
Electrical Hazard
Be sure that the top cover is securely in place before operating the ta7000F.
Since some service procedures require the cover to be removed while the
power is On, be aware that electric shock can occur. Therefore, only trained
or otherwise qualied personnel should service the ta7000F. The ta7000F is
supplied with a 3-conductor power cord providing a protective earth ground
connection when plugged into a properly wired receptacle. Proper receptacle
grounding must be veried.

PN T900-014, Rev B
Electromagnetic Compatibility (EMC)
Read and follow the recommendations in this section to avoid performance
variations or damage to the internal circuits of this equipment when installed
in harsh electrical environments.
The various congurations of the ta7000F should not produce, or fall victim to, electromagnetic
disturbances as specied in the European Union’s EMC Directive. Strict compliance to the EMC Direc-
tive requires that certain installation techniques and wiring practices are used to prevent or minimize
erratic behavior of the ta7000F or its electronic neighbors. Below are examples of the techniques and
wiring practices to be followed.
In meeting the EMC requirements, the various ta7000F congurations described in this manual rely
heavily on the use of metallic shielded cables used to connect to the customer’s equipment and pow-
er. Foil and braid shielded I/O and DC power cables are recommended for use in otherwise unprotect-
ed situations. In addition, hard conduit, exible conduit, and armor around non-shielded wiring also
provides excellent control of radio frequency disturbances. However, use of these shielding techniques
is eective only when the shielding element is connected to the equipment chassis/earth ground
at both ends of the cable run. This may cause ground loop problems in some cases. These should be
treated on a case-by-case basis. Disconnecting one shield ground may not provide sucient protec-
tion depending on the electronic environment. Connecting one shield ground via a 0.1 microfarad ce-
ramic capacitor is a technique allowing high frequency shield bonding while avoiding the AC-ground
metal connection. In the case of shielded cables the drain wire or braid connection must be kept short.
A two-inch connection distance between the shield’s end and the nearest grounded chassis point,
ground bar or terminal is highly recommended. An even greater degree of shield performance can
be achieved by using metallic glands for shielded cable entry into metal enclosures. Expose enough
of the braid/foil/drain where it passes through the gland so that the shield materials can be wrapped
backwards onto the cable jacket and captured inside the gland, and tightened up against the metal
interior.
Inductive loads connected to the low voltage “Alarm Contacts”are not recommended. However, if
this becomes a necessity, adhere to proper techniques and wiring practices. Install an appropriate
transient voltage suppression device (low voltage MOV, “Transzorb,”or R/C) as close as possible to the
inductive device to reduce the generation of transients. Do not run this type of signal wiring along
with other I/O or DC in the same shielded cable. Inductive load wiring must be separated from other
circuits in conduit by using an additional cable shield on the oending cable.
In general, for optimum protection against high frequency transients and other disturbances, do not
allow installation of the ta7000F where its unshielded I/O and DC circuits are physically mixed with AC
mains or any other circuit that could induce transients into the ta7000F or the overall system. Exam-
ples of electrical events and devices known for the generation of harmful electromagnetic disturbanc-
es include motors, capacitor bank switching, storm related transients, RF welding equipment, static,
and walkie talkies.

Overview
This manual is intended as a guide for operation of the AMETEK ta7000F Gas
Purity Monitor. This manual is not intended as a service guide and does not
contain service information. The ta7000F should only be operated by person-
nel who have been properly trained in the procedures required for safe opera-
tion of the ta7000F.
All photographs included in this manual are for example only, and
may not reect the actual as-purchased conguration of the ta7000F.
Introduction to the ta7000F Gas Purity Monitor
The ta7000F Gas Purity Monitor is a trace level gas chromatograph capable of
detecting sub-PPB concentrations of contaminants in sample gas matrices. The
system consists of a microprocessor controlled gas chromatograph using the
AMETEK Flame Ionization Detector (FID).
Because of the specic nature of the detection method, analysis times are
rapid and chromatographic complexity is minimized. The result is a simple reli-
able system capable of following rapid trends in component concentration in
process gas applications.
Overview |1-1

PN T900-014, Rev B
Functional Overview of the ta7000F Gas Purity Monitor
To achieve the specied performance, the ta7000F Monitor performs the pri-
mary functions described below.
Component Function
Carrier Gas Purication A Getter Purier is included as integral component of the car-
rier gas ow path. Impurities are reduced to a level of less than
100PPT.
Sample Introduction and
Component Separation
Samples are introduced into the instrument via air actuated
gas sampling valves. Components of interest are separated in a
1/8-inch Column(s) inside a heated column oven.
Flame Ionization
Detection (FID)
Species eluting from the FID column set pass immediately into
the heated bed of ruthenium oxide (Ru3O4) and the ame detec-
tor. Within the ruthenium oxide bed, the general reaction occurs:
COx+ (2+X)H2=> CH4+XH2O (vapor)
Where COx is an appropriate carbon-oxygen compound gas. For
carbon dioxide the equilibrium reaction is:
COx+ 4H2=> CH4+2H2O (vapor)
The resulting methane is quantitatively determined by means of
ame ionization immediately downstream of the ruthenium ox-
ide bed. Methane and other simple hydrocarbons pass through
the methanizer unaected. Within the ame ionization region
hydrocarbons are reduced via a series of reaction steps to CH+
ions and electrons prior to complete combustion into H2O and
CO2. The resultant electrons are collected to generate a current
signal. Higher hydrocarbons, those containing more than a
single carbon group, generate additional CH+ Ions in proportion
to the carbon number. As a result the theoretical sensitivity of
the ame ionization detector to non-methane hydrocarbons is
at least two times higher than methane.
Contamination of carrier gases with reactive compounds such as
suldes, chlorides, and aromatics will irreversibly impair reactiv-
ity and will necessitate methanizer replacement. Care should be
taken to bypass the instrument if these compounds are present
in the sample gas stream.

Component Function
Operating System The six (6) button keypad allows you to enter commands to the
microprocessor, which monitors detector operation, controls
heated zones, and operates all internal valve functions. External
signal outputs for a data collection system or host computer are
located at the ta7000F Rear Panel.
The microprocessor control system allows complete unattended
operation of the ta7000F. This onboard system performs neces-
sary operational and analytical functions such as:
• Analyzer Status Control
• Contaminant identication
• Concentration Calculations
• Calibration
• Sampling Frequency
• Data Output
• Alarm Output
Data is presented via the front display panel. Alternatively data
may be obtained through an RS-232 serial computer interface
and HP/GL parallel printer interface located on the Rear Panel.
With optional interface kits, two components may be assigned
to separate trend channels to provide a continuous signal
proportional to the concentration of the assigned component.
These trend signals are updated following each run and can be
tracked by a data logger or host computer.

Installation and Start-up
Safety Considerations
To ensure a smooth installation of the AMETEK ta7000F Gas Purity Monitor and
to get the maximum performance, several aspects should be considered. This
guide discusses the important points for a successful installation.
Before beginning the installation of the ta7000F and before powering
it up, review and follow all safety information following the Table of
Contents near the beginning of this manual. This information de-
scribes procedures to follow to avoid personal injury and/or damage
to the equipment. All regulatory agency and personnel safety proce-
dures for your jurisdiction must be followed.
The installation of the ta7000F must be in accordance with all of the
customer and local regulatory standards and procedures. There are no
operator-serviceable components inside the ta7000F. Refer all servic-
ing to qualied personnel.
Carrier Gas
The Flame Ionization Detector (FID) can be destroyed if operated at
temperature without ow. The carrier gas should remain owing until
all heated zones are below 50 °C (2–3 hours).
Line Voltage
Do not connect the power cord to line voltage without checking
the correct operating voltage on the label located on the ta7000F Rear
Panel.
Actuator Gas Pressure
Always maintain correct actuator gas pressure. Low pressure (below
70 PSIG) can result in failure of the internal valves and/or stoppage
of the gas ow to sensitive instrument components. High pressure
(above 150 PSIG) will damage the valve actuators.
Installation and Start-Up |2-1

PN T900-014, Rev B
Carrier Gas Puriers
External gas puriers must be completely conditioned with gas ow-
ing through them before connection to the ta7000F. Failure to prop-
erly condition puriers can result in serious contamination.
Flame Ionization Detector (FID) Flame Ignition
Do not ignite the FID ame unless the FID is at operation temperature.
Doing so will cause moisture to condense in the unheated FID and will
short out the electrometer input leads.
Electrical Signal Cables
Turn power O before connecting or disconnecting electrical signal
cables. Damage to circuit boards could result.
Shut Down/Cool Down
Be sure to turn O all heated zones and shut O the hydrogen supply
to the instrument prior to disconnecting gas supply lines. The carrier
gas should remain owing until all heated zones are below 50 °C (2–3
hours). After shutting O carrier gas, immediately cap all open gas
ports on the Rear Panel.
