3 Product description - technical specifications
The GC 5000 series has been developed for continuous monitoring of
organic compounds in air and gas streams. Depending on the application
requirements following models are available:
GC 5000 PROCESS
This instrument allows for monitoring of organic compounds in process and
industrial installations at ppm levels. The sample gas will be introduced
using a sample loop with well defined sampling volume.
The GC 5000 BTX
This instrument has especially been designed for ambient air monitoring
applications. The GC 5000 BTX features single-tube sample enrichment
technology and allows for monitoring of organic compounds at trace levels.
The GC 5000 VOC
This instrument has especially been designed for ambient air monitoring
applications. The GC 5000 VOC features dual-tube sample enrichment
technology and allows for monitoring of organic compounds from C
2
to C
6
at trace levels.
The following chapter describes the normal use of these three models.
3.1 Normal use of GC 5000 BTX
The AMA GC 5000 BTX suitable for the continuous monitoring of emission
and immission levels of organic compounds in ambient air and gas streams
in the range of C 4 – C 12 . The instrument is characterized by its detection
sensitivity in the low ppb to ppt range.
The analyzer is type approved according to EN 14662-3:2005 and suitable
for the legally obliged monitoring of benzene in ambient air according to the
guideline 2000/69/EC of the European parliament and the council from
November 16th 2000.
According to the EU guideline 2008/50/EC, the VDI guideline 2100 and the
guidelines of the Technical Assistance Document EPA/600-R-98/161 of the
American environmental protection agency EPA
of September 30th 1998 the analysis system is also suitable for the
continuous monitoring of ozone precursors in the range of C 4 -C 12 .
The AMA GC 5000 BTX has been developed for the continuous monitoring
General range of applications:
•Ambient air monitoring, immissions and emissions control
•Aromatic hydrocarbons (BTEX, styrene, trimethylbenzene, ethyltoluene)
•Aliphatic hydrocarbons (1,3-butadiene, methylcyclopentane,
methylhexane)
•Chlorinated hydrocarbons (vinyl chloride, trichloroethene, tetra-
chloroethene)

Operating Manual GC 5000; Version 6 English – Date 05/2014 11
The GC 5000 BTX analyzer is configured and calibrated ex factory with
your required standard application. This means that the equipment of the
system is adapted specifically to the required measuring task.
3.2 Normal use of GC 5000 VOC
The AMA GC 5000 VOC has been developed for the continuous monitoring
of emission and immission levels of organic pollutants in ambient air in the
range of C
1
– C
7
. The instrument is characterized by its compact design
and its outstanding detection sensitivity in the ppt-range.
According to the EU guideline 2002/3/EC from February 12th 2002, the VDI
guideline 2100 and the guidelines of the Technical Assistance Document
EPA/600-R-98/161 of the American environmental protection agency EPA
from September 30th 1998 the analysis system is also suitable for the
continuous monitoring of ozone precursors in the range of C
2
-C
7
(non-
aromatic).
A system for continuous monitoring of the complete range of ozone
precursor from C
2
-C
12
can be configured by combining the GC 5000 VOC
and GC 5000 BTX.
Range of applications:
•Ambient air monitoring, immissions and emissions control
•Aliphatic hydrocarbons (ethane, ethene, acetylene, propane, 1,3-
butadiene, pentane, 2-methyl-1,3-butadiene (isoprene), hexane)
•Chlorinated hydrocarbons (chloromethane, dichloromethane, vinyl
chloride, chloroethane)
The GC 5000 VOC analyzer is configured and calibrated ex factory with
your required standard application. This means the system is equipped
specifically for the required method. All necessary parameters have been
adjusted to the method.
3.3 Normal use of GC 5000 Process
The GC 5000 PROCESS has been developed for demanding applications
and operation under harsh condition in process and industrial installations.
The instrument allows for monitoring of organic compounds in air and gas
streams at ppm levels. Due to its modular design the GC 5000 Process can
be configured individually according to any specific requirement.
The temperature programmable air-bath oven is suitable for installation of
either packed or capillary columns. The temperature program with up to
three linear heating ramps allows optimization of the chromatographic
conditions in order to provide good peak separation.
Additional system modules complement the GC 5000 PROCESS providing
complete monitoring solutions. Any module features its own intelligent
Application
ex factory:
Application
ex factory:

electronics and can be controlled by the analyzer via internal bus
communications.
For these reasons the GC 5000 PROCESS covers a wide range of
industrial and process monitoring applications.
General range of applications:
•Emissions monitoring
•Continuous monitoring of waste air in drying and distillation plants

3.5 Description of GC components
3.5.1 System control and watchdog
System control is realized via a built-in PC board with Windows 7 and the
AMA control software.
Note
The GC 5000 features a hardware watchdog. In case of a software crash
or an operating system crash, the watchdog resets the internal PC. Then
the operating system and the AMA control software are started again
automatically and the GC 5000 is operating properly again. The
automated restart of the analyzer helps your service personnel: No extra
visits to the monitoring station are necessary.
3.5.2 GC oven
The GC module features a three step temperature program. It enables to
work with high end temperatures without having long cooling down-times as
construction and used materials of the GC components are characterized
by preventing from thermal inertia.
The dimensions of the oven are 21cm * 21cm * 8cm which makes app.
3500 cm
3
. The geometry of the oven allows the use of columns with their
own cages.
The maximum linear heating rate for the range between 40 -200°C is
25°C/min, adjustable in steps of 1°C/min.
3.5.3 Columns
The dimensions of the oven allow the use of commercial capillary columns.
This helps to exchange a column in a few minutes.
The GC can be equipped with capillary columns with an internal diameter of
0.32mm, 0.45mm or 0.53 mm and up to 60m length. For standard
applications use a 0.32mm column.
3.5.4 Detector
The standard detector is a FID (Flame Ionization Detector) or a PID (Photo
Ionization Detector). The output of the detector is an analog signal of 0-5 V.
The signal is digitized and analyzed by chromatography software.
3.5.5 Setup of parameters
The control software allows to enter and to modify all analysis parameters.
Unauthorized access is avoided due to password protection.

of different sources of sampling. The array consists of 3 valves and can be
used for one ambient source and two calibration sources. The needle
valves of the calibration gas cylinders have to be adjusted to 70ml/min or
more.
3.7.2 Ozone precursor monitoring system (optional)
For the on-line monitoring of hydrocarbons C2-C11 (ozone precursor) in
one system, the AMA BTX analyzer can be synchronized with an AMA VOC
analyzer via Ethernet.
The software will be already configured in the factory. Then the software of
the BTX analyzer will also control the VOC analyzer. On the monitor of the
VOC analyzer you will only see a display client. The parameter setup has to
be done on the BTX analyzer.

3.7.3 Optional Modules (Accessoiries for GC 5000)
3.7.3.1 Dilution Calibrator – DIM 200
The DIM 200 provides calibration gas at specified concentration levels for
precise calibration of monitoring devices. The calibration gas is generated
by diluting a source calibration gas with zero gas (e.g. nitrogen or purified
air).
The DIM 200 can be controlled manually or remotely via bus
communication by any AMA monitoring device or via digital I/O’s. This
allows for periodic validation and/or calibration of monitoring devices even
while running in unattended operation mode.
If the DIM 200 is controlled remotely by any AMA GC system, also setup of
the module is fully integrated into the analyzer software.
