Categories:: Information management | Standardization. General rules | Agriculture and Food | Food technology | Food products. Test methods and analysis

Scope

This European standard covers instrumental analysis by equilibration-isotope ratio mass spectrometry (Eq-IRMS) of liquid, aqueous food matrices to determine 18O/16O isotope ratios of the water of the product. The isotope ratios obtained by following this standard are expressed as delta 18O values relative to internationally recognised reference materials.

Sample preparation is not included within this European standard. It is assumed that the food sample has been pre-treated as necessary and homogenised.

The interpretation of the obtained isotope delta values is not covered by this European standard.

Purpose

A method for the determination of 18O/16O isotope ratios in liquid aqueous food matrices by Equilibration – Isotope Ratio Mass Spectrometry (Eq-IRMS) has been validated by mean of a ring trial, thus being important to be harmonised at European level.
