ENHANCED FEATURES
Advanced communications for remote access, 32 alarms, 32 relays, and intelligent functionality, including independent auto-
calibration to help minimize operational and maintenance costs.
It is backwards compatible with existing 4100 installations, complying with the same standards and agreements, making it easy to upgrade.
SERVOPRO MultiExact 4100 FOR
MEDICAL GAS MEASUREMENTS
An intuitive, icon-driven touchscreen interface allows easy interaction, while a USB serial port enables data logging, software
upgrades and duplication of analyzer configurations using a thumb drive.
RELIABLE MULTI-GAS ANALYSIS FOR MEDICAL GAS PURITY.
For many years, the SERVOPRO 4100
multi-gas analyzer has been a dependable
solution for monitoring medical gas purity.
This reliability continues in the SERVOPRO
MultiExact 4100, which combines
Servomex’s trusted gas sensing technologies
with digital stability and advanced features.
Configurable with up to four world-
leading gas analysis sensors in a single
platform, the MultiExact 4100 is designed
to measure simultaneous gas streams
including oxygen, nitrogen, methane,
nitrous oxide, carbon monoxide, argon,
helium and carbon dioxide.
For medical gas measurements, it is
typically fitted with a Paramagnetic
OXYGEN ASSAY ANALYSIS
For this application the MultiExact 4100
uses the inherently linear Paramagnetic
oxygen sensor with temperature control
and pressure compensation, giving a highly
stable reading for oxygen purity. It can also
offer an uncompensated Paramagnetic
oxygen sensor for medical air and a “not
oxygen“ measurement for EP argon where
temperature and pressure is not as critical.

Customized Infrared Gas Filter Correlation
(Gfx) and Thermal Conductivity Detector
(TCD) technologies provide the other
measurements. These ultra-stable, non-
depleting digital sensing technologies
deliver a low cost of ownership and
extended maintenance intervals. They
also provide accuracy at levels which
meet or exceed the requirements of the
European Pharmacopeia (EP) and US
Pharmacopeia (USP).

moisture measurement alongside
three other gas readings.

ANALYSIS
Using Infrared Gfx technology, the
MultiExact 4100 ensures a specific,
sensitive and stable measurement for this
application. The minimum range available
is 0-10ppm – however, the analyzer can
be calibrated over a 0-5ppm range to
satisfy EP requirements. Infrared Gfx technology is also used for
this application, providing a precise and
specific measurement with high stability.
The standard range is 0-500ppm, and this
can also be calibrated over a 0-300ppm
range to satisfy both the EP and USP
requirements for 300 and 500ppm CO 2 . The Infrared Gfx technology can also be
optimized for this application, delivering
an accurate, stable measurement of
methane in the 0-50ppm range, thus
satisfying EP requirements. Utilizing Servomex’s TCD technology, the
MultiExact 4100 is able to meet EP and
USP requirements for N 2 assay of 99.5%
and 99% purity respectively. The MultiExact 4100 can use each of
the separate technologies to meet the
purity requirement of >98% for N 2 O.
TCD is needed to fulfill USP regulations,
while the EP requires an Infrared Gfx
measurement.
