9.6 Master Standardization versus Reference Standardization
Vision provides two standardization methods: Reference Standardization and Master Standardization.
Reference Standardization is described in the Diagnostics section of this manual.
To avoid confusion the following table lists major differences between Reference Standardization and
Master Standardization:
Property Reference Standardization Master
Standardization
Supported by Metrohm
NIRSystems instruments Laboratory reflectance
systems, XDS Process All systems
Standardization algorithm Photometric offset correction
using a suitable standard to
achieve "absolute
reflectance". Photometric offset correction
at any reflectance or
transmittance level with
optional scaling
Standardization correction
storage In the analyzer's PROM In the Project or Library
database
Standardization type Global, one correction for all
methods marked as reference
standardized Local, various products or
projects can have different
corrections
NIST traceable Yes No
Allows to set up your own
master instrument Not Necessary Yes
Data Collection Method DCM’S are marked as such:
standardized or not-
standardized. Not dependent on DCM
