The Certification of the Mass Fractions of Tristearin in Blends of Pure Tristearin and Triolein Representing the Solid Fat Content - IRMM 805 (Set of 12 Primary Standards)
This report describes the preparation and certification of IRMM 805. This reference material is comprised of a set of 12 tristearin/triolein blends (primary triglyceride samples) for the solid fat content (SFC) determination by low-resolution nuclear magnetic resonance spectrometry (LR NMR).
The preparation and processing of the materials, stability studies and a characterisation study (by interlaboratory comparison) are described hereafter and the results are discussed. Uncertainties were estimated in compliance with the Guide to the Expression of Uncertainty in Measurement (GUM) and include uncertainties due to gravimetric sample preparation, purity and possible instability.
