TheFluoSens
Breakthrough in modern water analysis
FluoSens
is
an
advanced
fluorometer for the immediate
measurement of water ingredients
such as tryptophan or proteins
and organic pollutants, humic
acids and optional chlorophyll-a
from different kinds of microalgae.
The versatile FluoSens delivers
SAK values and transmission data
in a semi continuous flow through
mode. Different channels enable
prompt analysis from different
sources and allow estimation of
contents with the bbe++ software.
The applications:
Waterway analysis and assessment
Waterworks process monitoring
Pollution detection
Effluent/sewage water monitoring
Intake monitoring
Dam and river monitoring
Pig farm slurry survey

Operation of a three channel analytical device
Proposed set up of the instrument with a three channel multiplexing unit:
Overflow vessel
Sample 1
Sample 2
Sensor
Sample 3
Multi-channel unit
Outflow
The samples sources are connected to the multi-channel unit. The unit is equipped with valves
to select the appropriate channel.
High turbidity or larger particles may disturb the fluorescence measurement or clog the tubing.
Here it is recommended to connect the sample with an overflow vessel like Sample 1 in the
diagram.
If low turbidity is predominant the sample may be directly equipped with a T-fitting element
allowing the water to flow out in case the valve of multi-channel is closed.
Example measurement procedure for 3 channels and 30 minutes interval is shown on diagram
below:
valve 1 opened (8min)
measurement channel 1 (40s)
valve 2 opened (8min)
measurement channel 2 (40s)
valve 3 opened (8min)
measurement channel 3 (40s)
waiting time (~2min)
