Unique SALTTRAP located within the combustion

and low running costs
TOC analyzers from Elementar based on
catalytic high-temperature combustion have
been providing remarkable performance in
environmental and wastewater laboratories
for decades. Now the innovative enviroTOC
combines proven functions with new
technologies: the powerful furnace, variable
mode changes, real matrix separation
with SALTTRAP and the stable, wide-range
IR are complemented by a completely
new autosampler system and a novel
chemiluminescence detection system. This
makes enviro TOC the ideal, future-oriented
instrument for exible and ecient TOC and
TN
b determination in environmental and
wastewater samples.
HIGH-TEMPERATURE COMBUSTION
In compliance with international standards, the
TOC has to be oxidized at temperatures > 680 °C.
The temperature range from 680 °C to 750 °C is
ideal for the combustion of samples with a high
salt load. In addition, temperatures up to 1200 °C
ensure optimal oxidation conditions and excellent
recovery even of highly stable compounds such
as humic or fulvic acids or samples containing
particles, respectively. The robust furnace
of the enviro TOC with its flexibly adjustable
temperatures covers all these requirements and
guarantees a complete oxidation.
However, reliable carbon analysis of waste or
carbonates often requires higher temperatures.
Consequently, in solids mode operation of the
enviro TOC, the combustion enthalpy of the tin
capsules ensures a temperature increase up to
1800 °C.
TOTAL ORGANIC CARBON (TOC)
The TOC measuring principle of the enviro TOC is
based on catalytic high-temperature combustion
of the sample in an oxygen stream > 680 °C.
Under these conditions, all bound and dissolved
carbon is oxidized to CO
2?, which is determined
quantitatively with an IR detector. Sample pre-
treatment steps, e.g. for removing the inorganic
carbon from the sample, are fully automated.
The TOC analysis provides easily evaluable results
since matrix effects are negligible and the carbon
concentration in the sample correlates linearly
with the CO
2 signal. In comparison to other
techniques for the determination of organic
contamination, the use of hazardous substances is
avoided and the analysis time is a few minutes.
Designed for environmental samples
The analysis of TOC in wastewater to assess organic contamination
or to evaluate the cleaning eflciency of sewage treatment
plants is an international standard procedure. Also, TOC and TN
b
determination are indispensable for monitoring organic pollution
and nitrogen load in surface waters.
The enviro TOC is tailored to the analysis of TOC, NPOC, TC, TIC,
DOC, POC or TN
b in these matrices. Samples are injected with a
60-position autosampler. Integrated rinsing functions minimize
carryover during the analysis of particle-containing samples.
In addition, the measurement of soil samples or waste is also
possible without time-consuming instrument modifflcations. As
one of the few analyzers on the market, enviro TOC o?ers fully
automatic TOC determination in solid and liquid samples with
one system.
During the combustion of salt-containing samples, salts crystallize
in the combustion tube. If the crystallization occurs directly on
the quartz glass or in the catalyst, their lifetime is signi-cantly
reduced. The unique SALTTRAP of the enviro TOC guarantees user-
friendly maintenance intervals of the combustion tube and the
catalyst even for concentrated salt solutions, thus saving running
costs during operation. Depending on the nature of the salt, a
slight decrease in crystallization can be achieved by reducing the
combustion temperature. However, only SALTTRAP guarantees truly
eflective glass corrosion protection, because the salts are trapped
directly at the point where they melt.
Real matrix separation with SALTTRAP
The enviro TOC enables simultaneous TN b determination either
using the proven EC cell technology or a novel, integrated
chemiluminescence detector (CLD). The innovative CLD concept
provides stable conditions for NO measurement in the carrier
gas. Consequently, the NO signal is linearly correlated with the
TN
b concentration over a large measurement range. The built-in
CLD does not require additional laboratory space and delivers
extremely stable values, which simpli-es calibration as well as
result evaluation.

combustion. Matrix-independent
results. Stable calibration.
IN ACCORDANCE WITH OFFICIAL STANDARDS
The enviro TOC works in compliance with all relevant
standards for TOC, TC, TIC and TN
b in liquid samples such as
ISO 20236, ISO 8245, EN 1484, EN 12260, SM 5310B, EPA 415.1,
and ASTM D7573. Due to the unique solids option, TOC
and TC can also be determined in solids like soil or waste
according to EN 15936 and ISO 10694.
TOC / TN b analysis has never been easier!
Simple, fast conversion from
liquid to solid operation. Optional
nitrogen determination with an
integrated CLD or ECD.
Automated sample preparation
and injection, intuitive calibra-
tion and result evaluation. Easy
maintenance. Outstanding robustness and lon-
gevity thanks to state-of-the-art
technology. 10-year warranty on
the furnace and IR detector.
EASY AND COST-EFFECTIVE MAINTENANCE
The user-friendly maintenance concept of the enviro
TOC ensures the most efficient routine analysis: Our
goal is that the maximum lifetime of the instrument
can be reached with minimum maintenance effort.
Consequently, all consumables can be easily replaced by
the user. Clearly arranged, easily accessible components
guarantee that most maintenance work can be carried
out independently within a very short time. This saves
running costs and avoids downtime of the instrument.
