2 Description of the ISA Spectral Analyser
The ISA Spectral Analyser with its in situ submersible sensor head is available in three versions:
•ISA TS BlueBox TS with integrated spectrometer sensor unit1
•ISA T4 BlueBox T4 with one or more external spectrometer sensor modules
•ISA mobile ISA TS with two accumulator batteries and a power up control module
(Power Management Module PMM) integrated in a suitcase
The ISA measures the absorbance2in the wavelength range from 200 to 708 nm (UV/VIS). The result of a single
measurement is each a raw spectrum and an absorbance spectrum calculated there from over the entire
wavelength range.
A spectrometer is a very multi-purpose measuring instrument because it can be implemented in very diverse
applications through a relevant calibration. In contrast to electrochemical sensors, multi-parameter meas-
urements are also possible. Moreover, the ISA offers an adjustable measuring path length whereby the num-
ber of potential applications is increased even more.
A great advantage of the ISA is the special coating of the glass plates in the measuring path. Combined with
the possibility to automatically clean the measuring section with compressed air, the ISA achieves very long in
service times and maintenance intervals.
Only the optics and the compressed air cleaning are integrated into the high grade steel (material number
1.4404) or titanium sensor head. The entire control- and analysis-electronics are mounted in a BlueBox TS
with integrated spectrometer sensor unit or in an external spectrometer sensor module. The ISA is thereby
usable in a high temperature range (up to 110 °C). ISA is thus suitable for use in medicine or in the food indus-
try, since the measuring head can be sterilized at high temperatures.
All necessary settings are stored in the spectrometer unit, so the external spectrometer sensor modules can
be connected to another BlueBox without changing the BlueBox settings.3
The ISA can be used in potentially explosive areas, for details see 5.2 ATEX Notes.
The properties of the ISA in summary:
•Connection of the only optical sensor head with the analysis unit via the sensor head cable
(integrates two fibre optic cables and a compressed air line).
•Measuring path length freely adjustable from 0.5 – 20 mm
•Cleaning of the measuring section with compressed air
•Suitable for a wide temperature range (0 °C to +110 °C)
•Recording of absorbance spectra and raw spectra in the range 200 – 708 nm
•Saving of raw data and calibrated data
•Calibration and service software
•Remotely transferable calibration algorithms for parameter calculation
•Adjustment of calibration by remote maintenance
•Multi-parameter calculation
•Simple installation
•High cost-efficiency
1Further sensor units can be connected with external sensor modules via the CAN-bus interface.
2In absorption, radiation is absorbed by a substance. Further attenuating effects due to scattering or reflection are summarized
in the optics together with the absorption under the term absorbance, also called extinction.
3Applies only to current spectrometers, see 2.2 Notes on the Compatibility of Current and Older Spectrometers

Applications:
•Sewage treatment plants (inflow, outflow, process control)
•Industrial waste water (process water, waste water treatment)
•Waste water collection systems (load monitoring, corrosion protection)
•Water treatment, reuse and irrigation
•Environmental monitoring (monitoring of surface water)
•Aquacultures and fish farms
•Monitoring of landfill leachate
•Drinking water (source monitoring, process control, early warning of contamination)
•Groundwater management
•and other
Parameter examples:
•Nitrate: for NO3/NO3-N measurements
Measurement range 0.1 - 100 mg/l NOx_eq in water bodies (other measurement ranges are possible)
•Carbon compounds TOC/COD: Calibration by comparison analysis. Resolution and accuracy depend
on the stability of the water-matrix and its ability to be analysed.
2.1 Notes on Compressed Air Cleaning
In most applications, it is useful to use the compressed air cleaning of the spectrometer. The compressed air
line must be connected to the provided plug-in connection of the BlueBox TS or the external spectrometer
sensor module.
The air consumption of the compressed air cleaning depends on the connection pressure (4 - 6 bar) and the
back pressure in the medium and is at 6 bar at a maximum of 1 litre per second.
Example: At an interval of 60 seconds and a cleaning time of 5 seconds, the maximum consumption is 300
litres per hour.
2.2 Notes on the Compatibility of Current and Older Spectrometers
The CAN-ID∗of a current spectrometer (external spectrometer module and BlueBox TS) begins with ISA in
capital letters, e.g. ISA00001. The CAN-ID∗of an older spectrometer begins with isa in small letters.
The current spectrometers require a current BlueBox firmware version from 3.00.18 and a current BlueBox
PC Software version as from 4.2.0.0.
Older spectrometers are compatible with the current firmware and software.
2.3 Notes on the SQI (Spectral Quality Index)
The SQI is a degree of the statistical reliability of measurement values of an application-specific parameter
(see 9.3 The Sensor Setup Window of an Application-Specific Parameter). Precondition is the creation of a corre-
sponding calibration file in the xml format.
see Manual ISA and Process Spectrometer Commissioning - Maintenance - Service
see Appendix D – SQI (Spectral Quality Index)
∗In other contexts also called DAM-ID.

3.1 Scope of Delivery ISA TS, ISA T4
1. BlueBox
If the spectrometer will not be integrated into an existing BlueBox system, the BlueBox is part of the deliv-
ery. The BlueBox is the central control unit of the ISA. In the BlueBox measured data are saved and for-
warded, the values for the desired parameters are calculated and calibration parameters are stored. Via
the PC interface all ISA data and settings can be remotely controlled and read out for further processing.
The BlueBox is delivered with all the required accessories. Information about the properties, installation
and use of the BlueBox can be found in its attached manual.
2. Sensor-head
The ISA sensor head is manufactured from high grade steel (optional titanium). Only the optics and the
compressed air cleaning are integrated in the measuring head. The sensor head can thereby be deployed
in high temperature ranges (up to +110 °C).
3. Sensor-head-cable
The sensor head is connected with the spectrometer sensor module via the special covered sensor head
cable. The spectrometer sensor module contains all the electronics. In the measuring head cable there are
two fibre optic cables and a compressed air line. The probe cable must not be bent or kinked in a tighter
radius than 40 mm. At installation the sensor head shall not be hung up at the measuring head cable;
therefore use the appropriate lugs.

5.3 Schematic Structure
In the diagram below is a schematic representation of module interconnections in an example with ISA T4.
The Sensor module should be mounted close to the place of measurement. The maximum distance between
Sensor module and Sensor head is determined by the length of fibre optic cable (depending on version up to
10 m). The Sensor module and the BlueBox are in version ISA T4 connected by CAN-bus cable (type of cable:
LiYCY 2x2x0.5 mm² with an impedance of approx. 100Ω). Cable lengths up to 200 m are possible ∗, so that the
BlueBox as central control unit of the measuring system can be mounted in a control station.
A PC (or Notebook) with BlueBox system-software installed is necessary for the configuration of the system.
For direct connection with a PC/Notebook use a standard or crosslink network-cable.
6 Commissioning
The commissioning of the ISA spectrometer is described in detail in the attached
Manual ISA and Process Spectrometer Commissioning - Maintenance - Service .

7 Measurement Cycle
1. Cleaning (only when compressed air cleaning is active)
Compressed air cleaning of the sensor head optics (Duration: configuration parameter Cleaning time)
The frequency of the cleaning is determined by the configuration parameter cleaning interval.
1 cleaning before each measurement, 2 cleaning before each second measurement etc.
2. Wait (only when compressed air cleaning is active)
The wait time after flushing serves to ensure that air bubbles can dissipate.
(Duration: configuration parameter Waiting time)
3. Heating
The Xenon lamp is heated up through a few light flashes.
(Number of flashes: configuration parameter Heating)
4. Measuring
The period in which an actual measurement occurs. It consists of an individual measurement (Number of
light flashes per single measurement: configuration parameter Intensity) repeated a number of times
(Number of repetitions: configuration parameter Average). The final measurement result is the arithmetic
mean of the individual measurements.
5. Dark measuring
The dark measuring is a measurement without light flash and is used to compensate individual system
properties.
6. Interval
Interval is the period between the end of a measurement and the end of the next measurement.1
Measurement cycle without and with compressed air cleaning:
It is not possible to change configuration parameters during the measuring process time.2
1The measurement interval is calculated in advance from the set interval time and the configuration parameters. This results in
a low time drift of the recording times of the measured values.
2Except in extreme cases there is enough time for the input of settings after the end of the measuring process time to the begin-
ing of the next measurement cycle. The measurement process period is calculated from the Heating period, Dark measuring
period and Measuring period. The Heating period is generally negligible. The dark measurement is negligible too, because it
takes place only once.
Heating + Dark measuring + (Intensity x Average) 100 light flashes have a duration of approx. 1.6 s.

Switches to the input of the measurement interval = time period between the end of a meas-
urement and the end of the next measurement, lowest value is 3.∗
GO Systemelektronik recommends a minimum interval of 60, otherwise the lifetime of the
xenon flash lamp will be shortened.
see 8.1.1 Interval and Average
Switches to the input of the average: The number of single measurements from which the
arithmetic mean is derived. see 8.1.1 Interval and Average
Switches to the input of the measurement resolution.
Input 1 corresponds to decimal places = 0 in the sensor setup window,
Input 0.1 corresponds to decimal places = 1 in the sensor setup window, etc.
Switches to the Main menu.

Switches to the Main menu.
Wait until the end of a measurement before making an input.
∗The measurement interval is calculated in advance from the set interval time and the configuration parameters. This results in
a low time drift of the recording times of the measured values.

8.1.1 Interval and Average
Spektrometermenü 8.1
Interval: Measurement interval = time period between the end of a measurement and the end of the next
measurement, lowest value is 3.∗The larger the interval, the fewer spectra are stored, which shortens
download times and saves storage space. One absorbance spectrum needs 1540 Byte (1548 with GPS data).
GO Systemelektronik recommends a minimum interval of 60, otherwise the lifetime of the xenon flash lamp
will be shortened.
Average: The number of single measurements from which the arithmetic mean is derived. The arithmetic
mean values of the respective spectral values of the single measurements result the measured spectrum.
Current settings are displayed as "Actual value".
Deletes the last entered digit.

Wait until the end of a measurement before making an input.
8.1.2 Table and Diagram
The spectrometer measurement value displayed in the parameter display is the MVR (= Maximum digital Value
of a Raw spectrum).
These values are displayed as a table and diagram.
