Automotive fuels and fat and oil derivates - Determination of saturated monoglycerides content in Fatty Acid methyl Esters (FAME) - Method by GC-FID

This document specifies a method to determine the saturated monoglyceride content in fatty acid methyl esters (FAME). This method only identifies and quantifies the following saturated monoglycerides: 1-C16:0, 2-C16:0 and C18:0. The total saturated monoglyceride content is calculated by the summation of the contents of these three saturated monoglycerides.
This method is suitable for FAME prepared from rapeseed, sunflower, soybean, palm, animal oils and fats and mixtures of them. It is not suitable for FAME produced from or containing coconut and palm kernel oils derivatives because of overlapping of different peaks. The method does not quantify the C17:0 saturated monoglyceride, and is therefore not suitable for FAME’s containing significant levels of C17:0.

Autoraftstoffe und erzeugnisse aus pflanzlichen und tierischen Fetten und Ölen - Bestimmung des Gehalts von gesättigter Monoglyceride in Fettsäure-Methylester (FAME) - Methode mittels GC-FID

Dieses Dokument legt ein Verfahren zur Bestimmung des Gehaltes an gesättigten Monoglyceriden in Fettsäure-Methylestern (FAME) fest. Mit diesem Verfahren werden ausschließlich die folgenden gesättigten Monoglyceride bestimmt und quantifiziert: 1-C16:0, 2-C16:0 und 1-C18:0. Der Gesamtgehalt an gesättigten Monoglyceriden wird durch Aufsummieren der Einzelgehalte dieser drei gesättigten Monoglyceride berechnet. Die Präzision wurde für Fettsäure-Methylester mit einem Gehalt an gesättigten Monoglyceriden im Bereich von 200 mg/kg bis 1 500 mg/kg nachgewiesen.
Das Verfahren ist nicht geeignet für Fettsäure-Methylester, die auf der Basis von Kokosnuss- und Palmkernölderivaten gewonnen wurden, da sich verschiedene Peaks überschneiden.
ANMERKUNG   Mit diesem Verfahren werden ausschließlich drei gesättigte Monoglyceride bestimmt, d. h. 1-C16:0, 2-C16:0 und 1-C18:0. Fettsäure-Methylester können auch andere gesättigte Monoglyceride wie 1-C17:0 enthalten; allerdings sind diese in der Regel in wesentlich geringerer Konzentration vorhanden als die drei vorgenannten gesättigten Monoglyceride und wurden somit nicht in den Anwendungsbereich dieser Norm aufgenommen.
WARNUNG - Die Anwendung dieser Norm kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieser Norm, vor ihrer Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und dafür Sorge zu tragen, dass behördliche und gesetzliche Maßnahmen eingehalten werden.

Combustibles et produits dérivés des corps gras - Détermination de la teneur des monoglycerides saturés en esters méthyliques d'acides gras (EMAG) - Méthode par GC-FID

Le présent document spécifie une méthode permettant de déterminer la teneur en monoglycérides saturés (SMG) dans les esters méthyliques d'acides gras (EMAG). Cette méthode identifie et quantifie uniquement les SMG suivants : 1-C16:0, 2-C16:0 et 1-C18:0. La teneur totale en monoglycérides saturés est calculée en additionnant les teneurs de ces trois SMG. La fidélité a été établie pour des EMAG contenant des monoglycérides saturés dans une proportion de (200 à 1 500) mg/kg.
Cette méthode ne convient pas aux EMAG produits à partir de dérivés d'huile de noix de coco et de palmiste, ou en contenant, en raison du chevauchement de différents pics.
NOTE    La présente norme détermine uniquement trois monoglycérides saturés, à savoir les 1-C16:0, 2-C16:0 et 1-C18:0. Les EMAG peuvent également contenir d'autres SMG, tels que le 1-C17:0, mais ceux-ci ont généralement une teneur bien inférieure à celle des trois monoglycérides saturés ciblés, et ne sont donc pas inclus dans le domaine d’application de la présente norme.
AVERTISSEMENT — L'utilisation de la présente norme peut impliquer l'intervention de produits, d'opérations et d'équipements à caractère dangereux. La présente norme ne prétend pas aborder tous les problèmes de sécurité associés à son utilisation. Il incombe à l'utilisateur de la présente norme de prendre les mesures appropriées pour assurer la sécurité et préserver la santé du personnel avant l’application de la norme, et satisfaire aux exigences légales et réglementaires applicables à cet effet.

1 Scope
This document specifies a method to determine the saturated monoglyceride content in Fatty Acid
Methyl Esters (FAME). This method only identifies and quantifies the following saturated
monoglycerides: 1-C16:0, 2-C16:0 and 1-C18:0. The total saturated monoglyceride content is calculated
by the summation of the contents of these three saturated monoglycerides. The precision has been
established for FAMEs having saturated monoglycerides in the (200 to 1 500) mg/kg range.
This method is not suitable for FAME produced from or containing coconut and palm kernel oil
derivatives because of overlapping of various peaks.
NOTE This Standard determines only three saturated monoglycerides, i.e. 1-C16:0, 2-C16:0 and 1-C18:0.
FAMEs can contain also other saturated monoglycerides such as 1-C17:0, but these are generally much lower than
the three targeted saturated monoglycerides and are therefore not included in the Standard's scope.
WARNING — The use of this standard can involve hazardous materials, operations and
equipment. This standard does not purport to address all of the safety problems associated with
its use. It is the responsibility of the user of this standard to take appropriate measures to
ensure the safety and health of personnel prior to application of the standard, and fulfil
statutory and regulatory requirements for this purpose.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN ISO 3170, Petroleum liquids - Manual sampling (ISO 3170)
EN ISO 3171, Petroleum liquids - Automatic pipeline sampling (ISO 3171)
3 Principle
The saturated monoglycerides are converted into more stable and volatile silyl derivatives in the
presence of pyridine and N-methyl-N-trimethylsilyltrifluoroacetamide (MSTFA).
After silylation, the sample is analysed by gas chromatography on a capillary column with thin film
thickness, an on-column injector or equivalent device (e.g. programmed-temperature vaporizing
injector), and a flame ionization detector.
The quantification of the saturated monoglycerides is performed against the internal standard (IS)
Glyceryl monononadecanoate (mono C19), using a relative response factor of 1,00.
4 Reagents and materials
Use only reagents of recognized analytical grade. The reagents should not contain components that
chromatographically co-elute with the target components, i.e. 1-C16:0, 2-C16:0 and 1-C18:0.
NOTE Annex A shows a list of suppliers for saturated monoglyceride standards.
