The IV determination uses a global calibration in accordance with the AOCS-approved standard procedure Cd 1e_01. This global IV calibration is based on a wide selection of oils and fats obtained from multiple production facilities worldwide. 

The %Trans determination uses a global calibration based on a similarly wide range of oils. ABB’s world-renowned range of on-line and laboratory FT-NIR analyzers provide guaranteed transferability of calibration models between laboratory and process applications.

The accuracy and reliability of the FT-NIR based method has been evaluated via an official AOCS-supervised round robin test. Because of the inherent high reproducibility and stability of ABB’s FT-NIR analyzer technology, the analysis procedure is universally applicable to a wide variety of oils and fats without any calibration adjustments.
