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, Cl

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, N

¡
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.
