1.2. General Safety Regulations
Spare parts
and
disposables
Use only official Seres OL spare parts and consumables. If other
parts are used during the normal warranty period, the manufacturer’s
warranty is voided.
Modifications Modifications and instrument upgrades shall only be carried out by
an authorized service technician. Seres OL will not accept responsi-
bility for any claim resulting from unauthorized modification or alter-
ation.
Local
regulations
All wiring and connections (electrical, hydraulic) may only be carried
out by qualified personnel and in accordance with the local regula-
tions of the respective country.
WARNING
Electrical shock hazard
If proper operation is no longer possible, the instrument must
be disconnected from all power lines, and measures must be
taken to prevent inadvertent operation.
To prevent from electrical shock, always make sure that the
protective earth wire is connected.
Service shall be performed by authorized personnel only.
Whenever electronic service is required, disconnect the
instrument from power.
WARNING
Chemical exposure hazard
When handling chemicals or performing maintenance work
on hydraulic parts of the analyzer, wear suitable protective
equipment.
Read the Material Safety Datasheets (MSDS) of the chemicals
carefully.

WARNING
Do not use this instrument in presence of flammable liquids or
vapors as this may pose a safety hazard.
WARNING
If it is necessary to carry out maintenance work with the UV lamp
switched on, wear UV protective goggles.
1.3. Handling Precautions
Position the box correctly (up/down). Carefully unpack the analyzer
and check it for visible damage. If the analyzer shows any visible
damage, do not connect it to power and contact customer service
immediately.

2. Product Description
Application
range
The TOC Evolution VUV is a complete monitoring system for the
automatic, continuous measurement of total organic carbon (TOC) in
potable water and return condensate.
Measuring
principle
Advanced oxidation process with UV/VUV light and persulfate: By
purging the sample after adding acid, the inorganic carbon is con-
verted to CO2 and completely extracted from the sample. The sam-
ple is injected into the oxidation reactor. UV directly oxidizes the
organic matter which turns into CO2. The CO2 produced is then de-
tected by an NDIR (non-dispersive infrared) detector.
COD
correlation
Optionally, the measured TOC value can be correlated with the
chemical oxygen demand (COD). The COD is calculated using the
following equation:
COD = A * TOC + B
with A = COD correlation coefficient, B = COD offset.
The correlation has to be configured at the factory. Fill the equation
with the appropriate values for your sample and include them when
ordering the analyzer.
Note: The correlation is only valid if the customer's process
is stable and the customer is able to determine the correlation
equation.
Configurations The instrument is available in the following configurations:
Three measuring ranges:
– 0 to 2 ppm
– 0 to 10 ppm
– 0 to 100 ppm
available with one or two measuring channels (common
measuring range)
tangential filtration as an option (available with one measuring
channel only)
automatic calibration as an option

SOL-96.120.031 / 060223
TOC Evolution VUV

Tangential
filtration
(option)
The sample is pumped through a tangentially positioned membrane
filter with a mesh size of 100 μm. Only a small amount, approximately
1%, is drawn through the membrane filter and used by the analyzer.
A sample flow of 500 l/h results in a velocity of 1.75 m/s. At the point
where the membrane filter is located, the cross-sectional area of the
sample line is reduced to double the sample velocity. The higher ve-
locity helps to keep the membrane filter clean.
In addition, the membrane filter is cleaned by compressed air back-
flushing at 2.5 bar (air supply with 7 bar provided by customer). The
frequency and duration are automatically controlled by the analyzer.
Input On request:
One input for dry (potential-free) contact to stop measurement at the
end of the measurement cycle.
Signal
