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 (N
2
) are only digested partially or not at all.
TC
Total carbon
The total organic carbon and elementary carbon and contained CO
2
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
HNO
3
) 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 5100:
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.
