Foss NIRS DS3, User Manual

Page: 13 / 86

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.

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.
