1 About this user manual
The multi EA 5000 analyzer is intended for operation by qualified personnel with the
aid of this user manual.
The user manual contains descriptions of the design and operation of the multi EA 5000
and provides personnel experienced in analysis with the necessary information for the
safe handling of the basic module and its components. The user manual also includes
notes on the maintenance and care of the equipment and potential causes and remedies
for any faults.
Conventions Instructions for actions which occur in chronological order are numbered and combined
in action units.
Warnings are indicated by a warning triangle and a signal word. The type, source and
consequences of the hazard are stated together with notes on preventing the hazard.
¡Elements of the control and analysis program are indicated as follows:
¡Program terms are in bold (e.g., the System menu).
¡Buttons are indicated by square brackets (e.g., [OK]).
¡Menu items are separated by vertical lines (e.g., System | Device).
Symbols and signal words used The operating instructions use the following symbols and signal words to indicate haz-
ards or instructions. The warnings are always placed before an action.
WARNING
Indicates a potentially hazardous situation which can cause death or very serious (possi-
bly permanent) injury.
CAUTION
Indicates a potentially hazardous situation which can cause slight or minor injuries.
NOTICE
Provides information on potential material or environmental damage.

2 Intended use
The multi EA 5000 is a modular analyzer for determining the sulfur, nitrogen, chlorine
and carbon content in solid, liquid, paste-like, viscous and gaseous samples. Sample di-
gestion is achieved via pyrolysis and subsequent thermal oxidation of the achieved result
of the pyrolysis. The various element contents are determined in accordance with na-
tional and international standards by subsequent selective detection systems.
Depending on the functionality, the basic module includes at least one detection module
and one sampling module. The basic module and any connected modules are controlled
by the multiWin control and analysis software, and the analysis of the measurement
data is performed in this as well.
The analyzer may only be used for the analyses listed in the user manual. Only this spec-
ified use is regarded as the intended use, ensuring the safety of the user and the device.
Suitable sample types for the
multi EA 5000
The analyzer can be used for the following sample types:
¡Organic solids, e.g., wax, polymer
¡Organic liquids, e.g., fuels, solvents
¡High-viscosity organic liquids, gels and paste-like samples, e.g., crude oil, asphalt,
bitumen, tar
¡Organic gases and gas mixtures, e.g., natural gas, methane
¡Compressed liquefied gases, e.g., LPG, NPG, butane, propane, propylene
¡Carbon modifications, e.g., coal, elemental carbon, soot, coke
¡TC/TOC/TIC/NPOC in water analyses, e.g., waste water
¡EC/OC determination in particulate emissions, e.g., air quality control, three-way
catalytic converter research
¡AOX and EOX for water, sludge and soil via the column or batch method
Unsuitable samples The following sample types may not be analyzed with the multi EA 5000:
¡Highly flammable organic compounds – risk of explosion!
¡Self-reactive materials and explosives, e.g., peroxides, epoxides, azides
¡Organic and inorganic phosphorous compounds, e.g., phosphoric acid ester
¡Silico-organic and reactive or unstable inorganic silicium compounds, e.g., silane
¡Metal organic compounds, e.g., nickel carbonyl
¡Corrosive or highly-reactive substances, inorganic acids, HF, Cl2, H2SO4
¡Materials with high inorganic or organic salt content, in particular Na+ und K+ ions,
e.g., soil, fertilizers, feed, construction material
¡Inorganic compounds, e.g., minerals, inorganic halogens
¡Samples requiring more than 1100°C for complete oxidation or digestion, e.g., met-
als, alloys, N2
¡Pure elements, e.g., sulfur, nitrogen
¡Sample with element contents exceeding the permissible operating range.
¡TOC, TIC or TC analyses of solids, e.g., soil, sediment
Alkali salts and alkaline earth salts lead to crystallization of all quartz glass components
This process is accelerated by increased salt concentrations and combustion tempera-
tures, i.e. reducing the service life of the quartz glass components.
Gases used The device must only be used with argon and oxygen of the required quality as a carrier
gas.
Sum parameters Attaching the corresponding detectors and sampling modules allows the multi EA 5000
analyzer to determine the following parameters as sum parameters.

multi EA 5000 Intended use

Parameter Description
TS Total sulfur
Organically bound sulfur is detected. Inorganic sulfur compounds are
only digested partially or not at all.
TN Total nitrogen
Organically bound nitrogen is detected. Inorganic nitrogen compounds
and molecular nitrogen (N2) are only digested partially or not at all.
TC Total carbon
The total organic carbon and elementary carbon and contained CO2 is
detected. Inorganic carbon compounds are only digested partially or not
at all.
TX Total chlorine
The organically bound chlorine contained in the sample is detected.
Bromide and iodine compounds are only detected partially. Fluorine
compounds are not detected at all. The result is output as defined as to-
tal chlorine. Inorganic halogen compounds are only digested partially or
not at all.
EOX Extractable organically bound halogens
The EOX parameter is the sum of organically bound halogens (chlorine,
bromide, iodine) extracted under defined conditions from a water sam-
ple or from solids (sludge and sediment) using an organic solvent. Fluo-
rine is not detected.
AOX Adsorbable organically bound halogens
The AOX parameter is the sum of organically bound halogens (chlorine,
bromide, iodine) adsorbed under defined conditions (pH < 2 with
HNO3) from a water sample or a solid sample (sludge and sediment) in
active carbon using the vibration or column method. Fluorine is not de-
tected.
EC/OC Elementary carbon/organic carbon
The content of elementary carbon of a sample is detected directly after
the thermal desorption of the organic carbon. The amount of organic
carbon is then determined sequentially after thermal oxidation of the
remaining sample.
The following parameters can be determined from aqueous samples with the
multi EA 5000:
Parameter Explanation
TC Total carbon
TIC Total inorganic carbon
The total inorganic carbon from carbonates, hydrocarbonates and dis-
solved carbon dioxide is determined.
TOC Total organic carbon
The total organic carbon content is determined mathematically by cal-
culating the difference: TOC = TC - TIC. Determination of the TC and TIC
content of the sample is required for this.
NPOC Non purgeable organic carbon
The total non-purgeable organic carbon content of a sample is de-
tected. Highly volatile organic compounds are not or only partially de-
tected.
