Make the move to high performance

The compatibility of the FOSS NIRS DS2500 makes it easy to leverage data from System II and XDS units using straightforward transfer paths without any loss of performance. But why is it worth moving on from earlier technology?

Why take the next step?

NIRS DS2500 Feed Analyser

Advantages of moving to the new high performance platform include:

  • Wider choice of applications with higher performance across a broad wavelength of 400 – 2400nm
  • Calibrations can be shared across units
  • Better sample handling
  • Networking software link instruments for management by your own experts or via support from FOSS
  • Able to use ISI standardization, for example, instrument standardization to other technologies allows instruments to be used in a NIRSystem II or XDS network
  • More robust instruments that are less sensitive to humidity and dust
  • Internal standards for stability and recalibration - no more product standardization


Advanced monochromotor technology with easy calibration transfer

The innovative design of the NIRS DS 2500 avoids the problems of calibration transferability sometimes associated with NIR instruments. The spectrometer is equipped with internal standards for control of light intensity, bandwidth and wavelength position. Its stability can be validated to ensure that data transfer is continuously seamless, even over time.


Factory standardized instruments provide a stable platform over time

Instruments are factory standardized for quick implementation and the use of readymade calibrations. Instrument Standardization produces a mathematical adjustment which causes the spectra collected on a standardized instrument to match the spectra collected on the Master instrument.

Furthermore, once an instrument has been taken into use, in-built measurement standards help to control its performance to ensure that no deviations occur over time. This keeps continuous control of consistency between instruments and makes it easy to add any new instruments to your operation. Multiple instruments can easily use the same calibrations without any modifications.


Monochromator standardization options

You can recalibrate the monochromator to match other technologies, for example, to use the unit as part of an existing NIRSystem II or XDS network.

From NIRSystem II to NIRS DS 2500: examples

Alternative 1: Keep NIRSystems II as master using NIRSystems II calibration.
Requires: Single sample standardization applied to test set scans on the NIRS DS2500




Alternative 2: Change to NIRS DS2500 master
Requires: NIRSystems II calibration database standardized to NIRS DS2500 by applying single sample standardization. No standardization applied on test set scans from the NIRS DS2500



Alternative 3: Change to NIRS DS2500 master with enhancement
Requires: Enhancement of NIRSystems II calibration database with spectra from NIRS DS2500 without any standardization. No standardization applied on test set scans from NIRS DS2500
