NIRS™ DS3 / DS3 F is the fifth generation in a series of instruments designed for
high precision NIR measurement, characterisation of organic materials, and
qualification of known materials to allowable quality parameters. The instrument is
designed for stable operation in harsh environments, while providing the precision
and accuracy that users have come to expect of FOSS near-infrared (NIR)
instruments.
Fig. 1
NIRS DS3 / DS3 F uses a proven monochromator design, employing a digitally
controlled dispersive grating, sensitive detection devices, and state-of-the-art
circuitry to enhance signal/noise ratio and minimise any extraneous noise that
might influence performance. The instrument may be protected by one or more
patents listed at https://www.fossanalytics.com/en/news-articles/policies/patents.
This instrument uses near-infrared spectral energy in the range 400-2500 nm
(NIRS DS3) / 850-2500 nm (NIRS DS3 F) to illuminate the sample. By measuring
the energy reflected off the sample, chemical information and composition may be
determined. This information may be used for quantification of constituents.
ISIscan Nova offers an easy user interface, using the familiar interface structure
provided with previous generations of NIR instrumentation. All functions required
to perform quantitation are provided, with easy tools for interpretation of results.
ISIscan Nova offers full instrument diagnostics. ISIscan Nova stores all results in
an SQL database for later lookup, with control chart views of results tracked over
time.
Instrument communication is done through Ethernet connections. An Internet
Protocol (IP) address is dynamically requested upon connection. This address may
be permanently installed, if required for network purposes.
Connection through FossManager networking system allows for remote
surveillance and diagnostics checks of the instrument, if necessary and authorised.
The instrument enclosure is completely sealed to prevent contamination by dust or
other substances. The cooling fans operate outside the main enclosure and are
thermally linked to an internal cooling system that maintains a constant
temperature inside the instrument enclosure. There is no airflow drawn into the
optics chamber instrument.
Lamp changes are performed through a single panel on the instrument.
The lamp is easy to remove/replace and requires no special tools or expertise.
A sample, ground or unground, is placed in a sample cup which is placed in the
instrument. By means of a motor the cup is turned so that multiple parts of the
sample are scanned. This multipoint reflectance measurement allows for an
accurate analysis of the sample. Especially for inhomogeneous samples like pellets
it is crucial to have a multipoint measurement.
Fig. 4 Sample cup in instrument
All sample cups used with NIRS DS3 / DS3 F fulfil the ISO 12099 requirement of
a quartz window to eliminate drying effects of the interacting sample surface layer.
Analysis can be done with a range of different sample cups. The most commonly
used are the small cup and the large cup. Other cup types are shown in section
2.3.3 Other Cups and Accessories.
The small cup is intended for fine samples in granular or powder form and products
that are easy to compress. When placing the small cup in the sample presentation
unit the holder must be used. (The holder is shown between the sample cups in the
illustration below.)
The large sample cup is intended for unground or coarse samples like whole grains,
pellets or cut silage. The bottom and upper part of the large sample cup are screwed
together and can be taken apart, e.g., for cleaning or replacing the glass if needed.
The bottom part also fit with the Large Cup Extension.
If you are not sure of which cup to use for your application, please contact FOSS.
Fig. 5 Sample cups
There is a radio-frequency identification (RFID) tag on all cups. The RFID tag
contains information about cup type and a unique cup ID for each cup.
•The unique cup ID is stored together with each analysis providing traceability.
•The cup type can be connected to the specific application. A warning will be
generated if the wrong cup type is used with that application.
The use of RFID for cup type or cup ID control can be edited or disabled via the
software.

The best choice for samples that tends to stick to the cup. Also the preferred choice
for samples warmer than 50 °C. It should only be used for homogeneous samples.
For wet, sticky or otherwise unpleasant samples. Can be used with plastic or glass
petri dishes. The absorbance spectrum of the petri dish has to be taken into account
while developing calibrations.
The gold reflector is suitable for homogeneous, fairly transparent, liquid samples.
Liquid samples should preferably be analysed at a well-defined temperature since
temperature has a large influence on the shape of the moisture spectrum. When the
sample is placed in the cup, the gold reflector is placed over the sample. The
sample will quickly heat up or cool down to the temperature of the cup and gold
reflector. Keeping the cup and reflector at the same temperature thus ensures
consistent results. Depending on the product analysed, the required path length
may vary. Available path lengths for NIRS DS3 / DS3 F are 0.1 mm, 0.2 mm and
0.5 mm.

A holder that allows for use of the NIRS ring cup is available. This permits
scanning of an ISI ring cup on the NIRS DS3 / DS3 F. Its primary use is for cross-
standardisation between NIR platforms.

This chapter gives an overview of the two software programs used for operation
and network management of NIRS DS3 / DS3 F.
•ISIscan Nova
•FossManager
This user manual describes the main features and workflow for routine operations
in the ISIscan Nova software and some in the FossManager software, which is used
for configurations and setup. In both software systems you can find built-in Help
files which give further information on specific details.
The Help file in ISIscan Nova can be accessed either via by pressing the F1 key or
by clicking the question mark in the upper right corner in any view.
Fig. 9 ISIscan Nova help file
ISIscan Nova is the operating software for the NIRS DS3 / DS3 F. It contains all
necessary functionalities for the normal analysis routines:
•Select product and start analysis
•Enter Sample ID and other sample-related information fields
•Present results on screen, printer and/or transfer results to predefined network
location
•Detailed views for current or historic samples including audit trails for each
sample
•Generate result and diagnostic reports
•Perform diagnostics and instrument calibration
•Create backup of database
•Configuration for reporting, data transfer and backup paths
•Configuration and commands for communication with FossConnect server
•Initiate remote support session via Internet
FossManager is used for configuration of the ISIscan Nova user interface
determining what is available for the routine analysis operations:
•Active Products / Calibrations
•Operation profiles (e.g., which cup type to use for different products and
calibrations)
•Calculated parameters
•Icons, parameter names and units
•Mandatory and/or optional sample information fields
•Report templates
•Slope/Intercept and Moisture Compensation settings
FossManager can also be used for networking one or several instruments with
communication to/from a FossConnect server. The FossConnect server then also
has the function as a backup of all data, results and configurations.
Connecting instruments to one or multiple FossConnect servers enables remote
management of all configurations above as well as remote surveillance and
troubleshooting.
An instrument can be connected to a FossConnect server and at the same time run
local calibration models which are then administrated locally.
The two scenarios are elaborated below.
•The Routine Operator operates NIRS DS3 / DS3 F via ISIscan Nova software.
•One PC is used for both ISIscan Nova and Local configurator software. This
PC also contains the backup of data and configuration settings.
•Local Configurator connects to one single instrument.
