G ENERAL 2
VERTEX 70v is an evacuable, fully digital FT-IR spectrometer for demanding R&D
applications. The spectrometer is equipped with a number of features such as AAR
(Automatic Accessory Recognition) ACR (Automatic Component Recognition) and Per-
formanceGuard that facilitate performing spectroscopic measurements and ensure reli-
able measurement results. The function AAR identifies automatically the accessory
installed in the sample compartment, performs several tests and loads automatically the
corresponding experiment file including the pre-defined measurement parameters. The
feature ACR recognizes automatically the currently installed optical components like
source, detector and beamsplitter. These components are electronically coded so that
the spectrometer firmware can recognize them. This information is passed on to the
application software OPUS. The purpose of ACR is to enable the user to select the right
optics parameters in OPUS. In addition, the spectrometer components are monitored
permanently to ensure that they operate within the specification range. This feature is
called Performance Guard. Its purpose is to facilitate fault diagnostics and maintenance.
The data acquisition is based on a free running delta-sigma, dual-channel A/D converter
with 24-bit dynamic range. The A/D converter is integrated into the detector preamplifier
electronics. The DigiTect technology ensures a signal transmission free from interfer-
ences and guarantees the highest signal-to-noise ratio.
VERTEX 70v can be controlled by any data system (PC workstation, notebook etc.) on
which the operating system Microsoft Windows and the spectroscopic software OPUS is
installed. The Ethernet connection provides the possibility to control the spectrometer
also via your intranet or the internet.
The standard spectrometer configuration is designed for data acquisition in the mid IR
region. Optionally, VERTEX 70v can be equipped with additional optical components to
cover the whole spectral range - starting in the far infrared or THz region at 10cm-1 up to
the ultraviolet region at 28,000cm-1. Due to the pre-aligned optical components and the
permanently aligned RockSolid interferometer, the spectral range can be changed eas-
ily. If you work with the advanced spectrometer configuration (i.e. two detector positions
and two source positions are available inside the spectrometer) you can select them
using the software. Removable vacuum-tight covers provide access to the detector and
beamsplitter if you want to exchange these components.
VERTEX 70v has five IR-beam outlet ports (on the right, front and left side) and two IR-
beam inlet ports (on the right and rear side) allowing the connection of a multitude of
optional accessories and/or components like:
• TGA-coupling
• PMA 50 (Polarization Modulation Accessory for VCD and PM-IRRAS)
• HYPERION 1000/2000 IR microscope and HYPERION 3000 imaging
microscope with FPA detector (Focal Plane Array detector system)
• IMAC module (Imaging Accessory with FPA detector)

6 VERTEX 70v User Manual
2GENERAL
• External sample compartment (XSA)
• HTS-XT module (High Throughput Screening Extension)
• Fiber optic coupling module with MIR or NIR fiber probes for solid and
liquid samples
• FT Raman module (e.g. RAM II)
• FIR bolometer
• External, water-cooled sources
There is also the possibility to connect several accessories simultaneously (e.g. a
water-cooled Hg-arc source at the rear side, the RAM II FT-Raman module at the right
side, a fibre optics coupling at the right front side, the HYPERION IR microscope at the
left side and a bolometer detector at the front side).
Diagnostic routines help to maintain optimum instrument status and performance. The
internal validation unit (IUV) is located inside the spectrometer. It contains standards
(test samples) used for the validation and testing of the instrument.
Note: Depending on the spectrometer configuration you have ordered,
your spectrometer may not include all options that are described in
this manual.
The evacuable VERTEX 70v spectrometer allows measurements under vacuum condi-
tions, i.e. unwanted atmospheric interferents (e.g. water vapor or carbon dioxide) are
eliminated nearly completely from the spectrometer interior. Evacuating the spectrome-
ter is more efficient than purging it or using desiccant cartridges. The result of an opti-
mal measurement under vacuum conditions is an IR spectrum in which no H2O or CO2
absorptions mask weak spectral features of the sample.
The spectrometer design enables a separate evacuation of the spectrometer compart-
ments, i.e. either the complete spectrometer interior (sample compartment plus the opti-
cal bench) or only the optical bench can be evacuated. Vacuum shutters (so called
flaps), which can be equipped with optical or IR windows, allow a ventilation of only the
sample compartment in order to preserve the vacuum in the rest of the optics compart-
ment during a sample exchange or an accessory installation. Evacuating and venting
the sample compartment and/or optics are computer-controlled. Moreover, the spec-
trometer is equipped with two pressure sensors providing for the display of the current
pressure inside the spectrometer optics and/or sample compartment.
VERTEX 70v is supplied with an efficient vacuum pump that can evacuate the spec-
trometer optics within a few minutes. The oil-free vacuum pump prevents the spectrom-
eter optics from being contaminated by hydrocarbons.

devices are not connected to the same electrical circuit as the spectrometer.
•If a reliable mains power supply is a problem at your site (caused by brownouts,
power surges, frequent thunderstorms, for example), take precautions to ensure
an uninterruptible power supply.

SUPPLY
Power Cord
Before connecting the power cord, make sure that the spectrometer is switched off, i.e.
the mains switch (B in figure 2) is in the “O” position. Connect the supplied power cord
to the primary power receptacle (C in figure 2) as well as to the mains socket outlet.
The power cord length should not exceed 3m. Depending on the local conditions, the
original power cord may need to be exchanged for a power cord that complies with the
standards of the country in question. The power cord must have approbation of at least
your local authority, UL for US, CSA for Canada or VDE for Europe. The spectrometer
power supply unit automatically adapts to the local voltage and frequency range. (See
section Site Requirements.)

Data Cable
The data cable included in the spectrometer delivery scope is a CAT5 crossover cable
(labelled “Cross-over”) with two RJ-45 plugs. This cable is only used for the direct con-
nection of VERTEX 70v to a computer. If you intend to connect the spectrometer to a
network, a different type of cable (i.e. non-crossover, CAT 5 cable for the 10Base-T Eth-
ernet standard) is required. (See appendix E.) The data cable length should not exceed
100m (without repeater).
Connect one end of the data cable to the Ethernet port (ETH) (A figure 2) and the other
end of the data cable to the RJ-45 socket of the computer network interface card. (For
detailed information refer to the computer manual.)
After having set up the data cable connection, turn on the spectrometer using the mains
switch. After a few seconds, the spectrometer beeps once and starts a self test. After
the initialization has been completed successfully, the “STATUS” LED (figure 10) turns
from red to green. Now switch on the computer and the monitor. (For information on
how to install the computer and how to set up signal and power cable connections for
the computer, monitor etc. refer to the computer manual.)
Computer Setup
VERTEX 70v and the delivered PC are already configured for the stand-alone opera-
tion. The spectrometer IP address is factory-set to 10.10.0.1. In case you have not pur-
chased the computer together with the VERTEX 70v spectrometer, you have to assign
an appropriate IP address to the computer to which you want to connect the spectrome-
ter. For detailed information about how to assign an IP-address to the computer refer to
appendix E.

PUMP
The attachment flange (NW25 flange) for connecting the vacuum pump is at the spec-
trometer rear side. Figure 3 shows the valve block with removed cover.
The vent openings are covered by a plug made from sintered-powder metal which is air-
permeable (i.e. the spectrometer can be vented with the plugs installed on the vent
opening). (See figure 8.) The plug functions like a filter preventing particles from enter-
ing the spectrometer together with the influent air.
Note: For detailed information about the vacuum pump refer to the user
manual provided by the vacuum pump manufacturer.

INSTALLATION
Connecting VERTEX 70v to the Purge Gas Line
During operation, the vacuum pump generates vibrations. In order to prevent these
vibrations from being transferred to the spectrometer via the flexible metal hose, the
supplied vibration absorber has to be installed between the vacuum pump and the
spectrometer. The procedure for connecting the flexible metal hose to the vacuum
pump and to the vibration absorber is identical to the procedure described above.
Note: Make sure that the vibrating metal hoses do not come into contact
with the table on which the spectrometer is placed.
During the operation, the vacuum pump produces an increased noise level. In order to
reduce the noise level install the supplied noise reduction hood over the vacuum pump.
For information about the noise reduction hood installation refer to instructions provided
by the pump manufacturer.

GAS LINE
As an alternative to the vacuum operation, VERTEX 70v can be purged with either dry
air or dry nitrogen gas. The spectrometer has two purge gas inlets; one for purging the
sample compartment and the other for purging the optical bench. The purge gas inlets
are at the spectrometer rear side. See figure 7.

For detailed information about the required purge gas supply conditions refer to chapter
Operation, section Purging the Spectrometer.
Installation Procedure
Note: In case the spectrometer is evacuated, first vent it before starting
the installation procedure. Otherwise, a warning message regarding
unstable pressure conditions inside the spectrometer will appear.
•To connect the spectrometer to the purge gas supply you need a stiff hose with an
outer diameter of 6mm. Remove the plug (made from sintered-powder metal) from
the purge gas inlet by pressing the lock ring inwards (figure 8) and pulling out the
plug. Connect one end of the hose to your supply line for dry air or dry nitrogen
gas and insert the other end of the hose into the purge gas inlet for either the
sample compartment or optical bench.
•If you want to purge both the sample compartment and the optical bench, you
need a T-shape connecting hose with two hose ends leading to the spectrometer.
After having connected the main end of the hose to the supply line, insert one of
the other two hose ends into the purge gas inlet for the sample compartment and
the other hose end into the purge gas inlet for the optical bench.
