UNICUBE combines the low costs and the
sensitivity of a micro elemental analyzer
with the Nexibility and outstanding
robustness of a macro analyzer. UNICUBE
utilizes Elementar's proprietary and improved
direct Temperature Programmed Desorption
(direct TPD) technology for highest reliability
and performance in gas separation. In
combination with the most powerful detector
in the market, the instrument is capable
of determining samples with C:N and C:S
elemental ratios of up to 12,000:1.
HIGH-TEMPERATURE COMBUSTION
All elemental analyzers from Elementar are
designed for minimal sample preparation and
secure, unattended 24?/?7 operation. They use
the safe, simple and environmental friendly
high-temperature combustion principle.
The proven Elementar double furnace
technology with separated combustion and
reduction zone ensures longest maintenance
intervals. In combination with an efficient,
active oxygen dosing, it guarantees
quantitative conversion of the sample to
measuring gas — a prerequisite for highly
precise and matrix-independent elemental
analysis.
DIRECT TEMPERATURE PROGRAMMED
DESORPTION (DIRECT TPD)
UNICUBE uses the proprietary direct TPD
technology to chromatographically separate
the combustion gases prior to detection in a
highly sensitive thermoconductivity detector.
The temperature program for the gas separation
is controlled by a sensor positioned on the
inside of the direct TPD column - directly in the
gas stream. This setup has unique benefits such
as very sharp peaks through direct control of
the gas desorption temperature and guaranteed
baseline separation of all gases - even for
extreme elemental ratios. This makes the direct
TPD technology capable of resolving C:N and
C:S ratios of up to 12,000:1. The distinct peak
separation assures absolutely reliable and
trouble-free data acquisition. Elementar’s
unique direct TPD columns are optimized to
provide unmatched robustness and longevity
compared to classic GC columns.

Reliable results
UNICUBE guarantees outstanding precision and accuracy
through quantitative combustion via oxygen jet-injection
directly into the combustion zone. This leads to matrix-
independent results even for samples which are di?cult
to combust. In combination with the state-of-the-art
thermoconductivity detector, the instrument can provide
an elemental detection limit down to < 50 ppm.
Ease of use
UNICUBE is optimized to simplify daily routine operation. Clearly
arranged, easily accessible system components as well as a
furnace that slides out minimize maintenance and maximize
uptime. The tool-free clamp connection system ensures a reliably
leak-tight instrument at any time. Thus, users can enjoy smooth
analyses and confidence in their results.
Thanks to a novel self-regulating cooling air circulation,
UNICUBE becomes the quietest elemental analyzer in its
class. A low noise level - not louder than falling rain -
makes working with UNICUBE pleasant to your ear.

UNICUBE - high perfomance becomes easy-going
ONE INSTRUMENT FOR MULTIPLE TASKS
For the determination of very low S concentrations
down to 2?ppm, UNICUBE can be equipped with
an optional IR detector even in CHNS mode. Even
oxygen and chlorine can be detected. All optionally
available conversion kits allow upgrading UNICUBE
at any time for special applications.
The UNICUBE
® trace version obtains detection limits
down to 10 ppm N.
QUALITY YOU CAN TRUST
Thanks to the outstanding robustness and
longevity, all analyzers include a 10 year warranty
on high temperature combustion furnace and
thermoconductivity detector (TCD) cell. With the
confidence that you will receive the highest level
of technical support from our experienced team,
Elementar provides spare parts for a minimum of
10 years after the end of production. This results in
outstandingly low total cost of ownership.
