TOC, ROC AND TIC IN SOLIDS
With the optional solid sample combustion
unit it is possible to determine different
carbon species in solids using the so-called
temperature ramp method - fast and safe
without acidification. With this it is possible
to distinguish between Total Organic Carbon
(TOC) at 400 °C, Residual Organic Carbon
(ROC) at 600 °C and Total Inorganic Carbon
(TIC) at 900 °C. This gives useful information
for the validation of soil, construction waste
or solid waste. For example, the amount
of elemental carbon is an important
parameter, since this form of carbon is not
bioavailable. With its fast heating rate and
precise temperature setting the acquray
series is fully compliant to the German
DIN 19536 standard.
TOC BY WET CHEMICAL OXIDATION
A strong oxidation agent, such as sodium
peroxydisulfate, is added to the sample and
heated up to 100 °C. The oxidizing process
can be further supported by irradiation with
UV light at a wavelength of 180 nm and
254 nm. The peroxydisulfate forms hydroxyl
radicals that oxidize all carbon in dissolved
organic matter to carbon dioxide. Carrier
gas then transports the generated CO
2
through an infrared detector. The peak area
is converted into a TOC concentration using
a simple predetermined calibration curve.
series
With the new acquray series Elementar
opens an entirely new way for easy Total
Organic Carbon (TOC) analysis and more. The
technology is based on a chemical oxidation
process supported by highly energetic UV
radiation. This combination ensures complete
digestion of all organic compounds. The
modular concept allows the attachment of
optional extra modules for the determination
of TOC in solids, Total Nitrogen (TN) in water
and Total Phosphorus (TP) in water. The
instrument comes with predened methods,
completely calibrates itself automatically and
auto-alerts the user any time maintenance
is needed. This makes the acquray series the
ideal solution for routine labs that require
instruments with high laboratory eciency
and minimal down-time.
Ease of use
The acquray series is optimized to signiflcantly simplify the
daily routine operation. Clearly arranged, easily accessible
system components minimize maintenance eorts. Thus,
customers can enjoy smooth analyses and confldence in
their results.
A workhorse for any laboratory
The acquray series is designed for maximum robustness and
minimal maintenance eort, thus providing industry-leading
system uptime. For unattended overnight operation, optional
autosampler conflgurations with up to 109positions are
available.
The acquray series, with its modular concept, oers an in-
dustry-leading versatility. Starting from the TOC analyzer base
module, additional extra modules can be attached at any -
time. For increased sample throughput, an autosampler unit
is available, oering several carousels for dierent sample vial
sizes. An optional combustion furnace for solid samples can be
used either for the classical TOC analysis of solids via acidi-
cation prior to combustion, or for the more advanced method
via temperature ramping without acidication. Completing
the package, another two unique modules are available that
enable the determination of Total Nitrogen in water and
Total Phosphorus in water. Thus, acquray is the world’s rst
UV-digestion TOC analyzer with a Total Nitrogen and/or a Total
Phosphorus option (patent pending).
All Elementar elemental analyzers are developed and man-
ufactured in-house at the Elementar headquarters near
Frankfurt ensuring high quality German engineering. High
performance components and strict quality control yield
industry-leading quality and reliability. Designed for easy lab-
oratory integration, features such as automatic weight transfer
from balance or LIMS integration are readily available. Our
team’s singular devotion and investment to elemental analysis
guarantees a superior experience that any user will appreciate.

THE ALTERNATIVE FOR COD
The analysis of the chemical oxygen demand (COD) is a
commonly used method for the indirect measurement
of organic compounds in water. Hazardous chemicals,
long analysis time and the lack of automation explain
the trend towards the TOC method in recent years.
Moreover, production and sales of potassium dichromate,
a prerequisite for the COD method, will be banned within
the European Union by 2017 making it likely that a total
displacement of COD will proceed in the upcoming years.
With this in mind, the acquray series was developed
to provide an attractive alternative to COD with its
outstanding ease of use and fully automated, fast analysis.
Furthermore, the acquray series software is capable of
COD/TOC correlation factors for flexible reporting.
IN ACCORDANCE WITH STANDARDS
The acquray series operates in full compliance with all
relevant national and international norms or standards
such as DIN 19539, DIN 15936 and DIN 13137.
