Applications de mesure de la stabilité
La stabilité à l'oxydation est un indicateur important de la stabilité du produit et de sa durée de conservation. Nos experts en applications ont compilé de nombreux documents sur la détermination de la stabilité à l'oxydation dans divers échantillons, tels que les huiles et les graisses, le biodiesel ou les matières premières pharmaceutiques.

- AB-204Oxidation stability of oils and fats – Rancimat method
This document outlines Rancimat testing for both liquid and solid food samples, including direct and PEG methods, for oxidation stability QC in the food industry.
- AN-R-035Oxidation stability of spices and seasonings with the PEG method
Processing degrades antioxidant levels in spices. The 892 Professional Rancimat determines oxidation stability with the PEG method as per AOCS Cd 12b-92 and ISO 6886.
- AN-R-030Oxidation stability comparison of AOCS Cd 12b-92 and EN ISO 6886
The oxidative stability of sunflower oil using AOCS Cd 12b-92, EN ISO 6886, and a method based on EN ISO 6886 from Metrohm are compared. No significant differences are found.
- AN-R-009Oxidation stability of fatty acid methyl esters (FAME, biodiesel)
In this Application Note, the 893 Professional Biodiesel Rancimat measures the oxidation stability of biodiesel (or fatty acid methyl esters, FAME), an eco-friendly fuel.
- AN-R-034Oxidation stability of diesel, biodiesel, and blends
Sustainable biodiesel can be blended with petroleum diesel. The 893 Professional Biodiesel Rancimat measures the oxidation stability of biodiesel and its blends.
- AN-R-033Détermination de la teneur en antioxydants avec le PEG comme matériau de support
Une teneur plus élevée en antioxydants signifie une plus grande viabilité du produit. Le 892 Professional Rancimat détermine la teneur en antioxydants de nombreux produits à l'aide d'une méthode de régression linéaire.
