Useful Terminology
BTEX is an acronym that stands for benzene, toluene, ethylbenzene,
and xylenes.These compounds are some of the volatile organic
compounds (VOCs) found in petroleum derivatives such as petrol (gasoline).
Toluene, ethylbenzene, and xylenes have harmful effects on the central nervous
system. BTEX compounds are notorious due To the contamination of soil and
groundwater with these compounds. Contamination typically occurs near
petroleum and natural gas production sites, petrol stations, and other areas with
storage tanks containing gasoline or other petroleum-related products.
The amount of 'Total BTEX', the sum of the concentrations of each of the
constituents of BTEX, is sometimes used to aid in assessing the relative risk or
seriousness at contaminated locations and the need of remediation of such
sites. Naphthalene may also be included in Total BTEX analysis yielding results
referred to as BTEXN. In the same way, styrene is sometimes added, making it
BTEXS.

Useful Terminology
 Flame Ionization Detector FID
The operation of the FID is based on the detection of ions formed during
combustion of organic compounds in a hydrogen flame.
The generation of these ions is proportional to the concentration of
organic species in the sample gas stream. In order to detect these ions,
two electrodes are used to provide a potential difference
 Gas Chromatograph (GC)
GC is a chemical analysis instrument for separating chemicals in a
complex sample. It uses a flow-through narrow tube known as the column,
through which different chemical constituents of a sample pass in a gas
stream at different rates depending on their various chemical and physical
properties and their interaction with a specific column filling, called
the stationary phase. As the chemicals exit the end of the column, they are
detected and identified electronically. The function of the stationary phase
in the column is to separate different components, causing each one to
exit the column at a different time

VOC Analyzer – Model 4060 GC
Model 4060 is a microprocessor based instrument ideal for the specific
monitoring of trace levels of Benzene in gases such as carbon dioxide, air, and
nitrogen. Designed as an on-line analyzer the Model 4060 comes with three
standard ranges, the most sensitive at 100 ppb full-scale. This analyzer can be
configured to measure BTEX measurements + 1,3 Butadiene.
Because of its relatively high sensitivity to most organic compounds, the flame
ionization detector is a powerful tool for measuring hydrocarbon impurities in
other gases. It also provides a linear response over a wide range of analysis .
The Organic compounds from the sample stream or separation column are
injected into the detector housing where they are mixed with Hydrogen and air
before entering the detector jet where the mixture is burned. During this
process, organic compounds are broken down into carbon fragments and
acquire a positive charge (i.e., become ionized) at the surface of the anode.
Carbon fragments are detected by the collector. The signal is then amplified and
sent to the data processing system

Modes of Operation: The analyzer has 2 modes of operation depending on the position
of the GC Sampling Valve.
Sampling Mode (Valve Position A)
the analyzer configures the operational valve to back flush the column and charge
the sample loop. The Sample Mode is programmed to continue for a 7 minute
period by factory default; however, it is usually modified to match the needs of a
particular process. It is possible to set the Sample Mode duration up to 25 minutes.
Analysis Mode (Valve Position B)
In this mode the analyzer configures the sampling valve to feed the gas in the sample loop
through the column and to the detector. The eluted sample from the column is fed to the FID
for the analysis of the compound of interest in the hydrocarbon stream. If configured to do
so, the analyzer may read the detector for a programmed 5 second period at some point
within this mode cycle to obtain a baseline reading for further calculation. This mode is
usually programmed to continue until the compound of interest is fully eluted from the column. It is
possible to set it up to 25 minutes.

4060 GC - Equipment
The following supporting gases and hardware will be required to operate the
analyzer:
1. Fuel: A cylinder containing a hydrogen gas, zero gas quality composition will
be required to supply the fuel for the flame ionization burner. The cylinder is
to be equipped with an oil-free metallic diaphragm regulator (dual stage).
2. Blanket Air: A cylinder of compressed air, zero gas quality will be required to
maintain the proper atmosphere within the cell. The cylinder is to be
equipped with an oil-free, dual stage, metallic diaphragm regulator.
3. Carrier Gas: A cylinder of nitrogen gas, zero gas quality, equipped with dual
stage metallic diaphragm regulator is required.
4. Span Gas: A cylinder or a permeation device system, capable of generating
known concentration of benzene and/or other aromatic hydrocarbons of
interest, will be required to calibrate the analyzer.
5. Sample Pressure Regulation: An oil-free, metallic diaphragm regulator
must be installed at the sample point when possible.

4060 GC - Tracs Diagnostic Software
 Tracs™ software developed by TAI is a unique program to unveil
chromatogram and compound retention sequences on which concentrations of
compounds of interest are calculated. It provides valuable access for an
ordinary user to look into inside the complicated GC world with a computerized
tool. It suits the needs for high accuracy in GC technique and for ease of
communication in digital format.

ALARM RELAYS:
The nine alarm-circuit connector pins connect to the internal alarm relay contacts. Each set
of three pins provides one set of relay contacts.
Threshold Alarm 1:
 Can be configured as high (when concentration is above threshold), or low
(when concentration is below threshold).
 Can be configured as failsafe or non-failsafe
 Can be configured as non-latching
 Can be configured out (defeated).

Threshold Alarm 2:
 Can be configured as high or low

Can be configured as failsafe or non-failsafe
 Can be configured as non-latching
 Can be configured out (defeated).
System Alarm:
Actuates when DC power supplied to circuits is unacceptable in one or more
parameters. Permanently configured as failsafe and latching. Cannot be defeated
17
VOC Analyzer – Model 4060 GC
The Alarms Function:
The Model 4060 is equipped with two alarms and a system failure alarm relay
 1-DEFEATED: If an alarm is defeated, its relay is de-energized, regardless of
failsafe condition. A defeated alarm does not react to a transition over its trip
point in either direction.
 2-HIGH: If an alarm is set as HIGH, it will not create a new alarm condition if
the analysis concentration is below the trip point, if the analysis concentration
is above the trip point, then an alarm condition will be created or maintained.
 3-FAILSAFE: A non-defeated alarm that is in FAILSAFE mode energizes an
alarm relay in a non-alarm condition and de-energizes an alarm relay in an
alarm condition.
18
VOC Analyzer – Model 4060 GC
 4-LATCHING: The latching property configures the alarm such that the user
must manually relieve the alarm condition even though the concentration no
longer violates the trip point of the alarm. So, if an alarm is NON-LATCHING,
and the analysis concentration temporarily drifts above the trip point of a HIGH
alarm, the alarm condition occurs only during the time the concentration is
above the trip point. If that alarm were LATCHING, the alarm condition would
persist (even though the concentration is no longer above the trip point), until
the user released it.
 5-TRIGGER POINT: This is the threshold at which an active alarm can enter
into alarm condition. If an alarm is HIGH, ACTIVE, and set at 20.00 ppb, then
when the analysis concentration is at or above 20.00 ppb an alarm condition is
initiated or maintained.

ELECTRO-STATIC DISCHARGE
Modern electronic devices such as the types used in the various electronic
assemblies of your analyzer, are very small, require very little power and operate
very quickly. Unfortunately, the same characteristics that allow them to do these
things also make them very susceptible to damage from the discharge of static
electricity. Damage to components occurs when these static charges come into
contact with an electronic device.
Temporary anti-ESD work area

Always wear an Anti-ESD wrist strap when working on the electronic assemblies of
your analyzer.
 Simply touching a grounded piece of metal is insufficient. While this may temporarily
bleed off static
 Always store sensitive components and assemblies in anti-ESD storage bags or bins
MAINTENANCE PROCEDURES please refer to P 65 of the manual
