NIRS™ DS2500 Feed Analyzer

Why take the next step?

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 standardisation

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 standardised 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

Performance across the full wavelength range of 400 to 2500 nm

The innovative use of technology according to the demands of particular routine analysis applications is a principle behind all FOSS dedicated analytical solutions.

Predispersive monochromator A holographic grating separates white light into individual wavelengths. An encoder correlates the position according to the wavelength and filters ensure that only first order radiation (most intense) is made available from 400 nm to 2500 nm in a single scan.

Advantages of monochromator technology

When designing the next step in NIR, our talented engineers chose to make use of the latest in predispersive monochromotor technology as the most stable and versatile option for routine feed analysis.

It was chosen for its high signal to noise (S/N) ratio across the whole range. This gives accurate analysis of parameters commonly measured with NIR as well as demanding parameters such as amino acids and other low level parameters in need of high accuracy.

In comparison, Fourier Transform near infrared (FT-NIR) is a powerful technology, but this strength lies mainly at wavelengths over 1800 nm. Diode array is another excellent technology but, the S/N ratio falls above 1650 nm.

Calibration transfer

The innovative design of the NIRS DS 2500 also avoids the problems of calibration transferability sometimes associated with monochromator-based 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.

Overall, the monochromator technology offers:

• Unsurpassed S/N ratio from 400 – 2500 nm and thereby high resolution spectra over whole wavelength range
• Versatility in choice of applications for example, amino acids, astaxanthin and chlorophyll alongside the more commonly measured parameters
• Excellent calibration transferability with internal standards to control the stability of the spectrometer
