For matching between NIRS DS3 / DS3 F and an existing Network Master
instrument from FOSS, the instrument can be set up to use either the XDS (default)
or the NIRS 5000/6500 compatibility mode.
Which mode to use is defined in FossManager software and is linked to the
Operation Profile. 5000/6500 compatibility mode should only be used if the
Network Master you are standardising towards is a NIRS 5000 or NIRS 6500.
Every time an Instrument Calibration (internal or external) is carried out in ISIscan
Nova both wavelength scales are automatically recalibrated, meaning that you do
not need to choose the wavelength scale at the time of instrument calibration.
Intensity Correction is part of the Instrument calibration and cannot be done as a
separate function.
Intensity Correction (with the ERC standard) is a method to provide a virtual 100%
reflectance reference at true sample interface, making measurements independent
of the physical design. This is important in order to achieve a high-quality
spectrum on each instrument and to secure transferability between instruments.
The Intensity Correction procedure corrects for possible differences in the
instrument's optical path, such as influences from glass impurities etc. The
determined correction is applied to every spectrum taken on the instrument to make
each spectrum appears as if taken with a reference of 100% reflectance. This
assures that spectra obtained on different instruments are perfectly aligned with
each other.
The ERC cup is included with all deliveries of NIRS DS3 / DS3 F.
