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 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.
Kraftstoffe und Erzeugnisse aus Fetten und Ölen - Bestimmung des Gehalts an gesättigten Monoglyceriden in Fettsäure-Methylester (FAME) - Verfahren mit 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.
Carburants pour automobiles et produits dérivés des corps gras - Détermination de la teneur en monoglycérides saturés (SMG) des 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.

Overview
EN 17057:2018 (CEN) defines a validated analytical method for the determination of saturated monoglyceride (SMG) content in Fatty Acid Methyl Esters (FAME) using gas chromatography with flame ionization detection (GC‑FID). The method specifically identifies and quantifies three saturated monoglycerides: 1‑C16:0, 2‑C16:0 and 1‑C18:0. Total saturated monoglyceride content is reported as the sum of these three components. Precision has been established for FAME samples in the 200–1 500 mg/kg range. Note: the method is not suitable for FAME produced from or containing coconut and palm kernel oil derivatives due to peak overlap.
Key topics and technical requirements
- Analyte scope: 1‑C16:0, 2‑C16:0 and 1‑C18:0 (other SMGs such as 1‑C17:0 are not included).
- Sample derivatization: Silylation with N‑methyl‑N‑trimethylsilyltrifluoroacetamide (MSTFA) in pyridine to form volatile, stable derivatives prior to GC analysis.
- Internal standard: Glyceryl monononadecanoate (1‑C19:0) used at a stock concentration of 2.5 mg/ml; a relative response factor of 1.00 is applied.
- Chromatography: Capillary, high‑temperature columns (examples: DB‑5HT 30 m × 0.25 mm × 0.1 µm or CP9078 15 m × 0.32 mm × 0.1 µm), on‑column or PTV injection, and FID detection. Typical analysis time ~30–35 minutes.
- Carrier gas: Hydrogen or helium (min. 99.999 %).
- Column performance: Resolution requirements to avoid co‑elution with common interferents - n‑C26 / 1‑C16:0, squalene / 1‑C18:0, and n‑C28 / 1‑C18:0 each require R ≥ 1.0.
- Sample prep & injection: Typical protocol-heat sample (40–50 °C), weigh ~100 mg, add IS, pyridine and MSTFA, react 15 min, dilute with n‑heptane and inject 1 µl.
- Safety: The standard contains a safety warning-users must manage hazardous reagents and equipment and comply with applicable health and safety regulations.

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.

La norme EN 17057:2018 est un document clé qui spécifie une méthode pour déterminer la teneur en monoglycérides saturés dans les esters méthyliques d'acides gras (FAME). Elle se concentre spécifiquement sur l'identification et la quantification des monoglycérides saturés 1-C16:0, 2-C16:0 et 1-C18:0, permettant ainsi un calcul précis de la teneur totale en monoglycérides saturés à partir de la somme de ces trois composés. Un aspect fort de cette norme réside dans sa précision, qui a été établie pour les FAME contenant des monoglycérides saturés dans une fourchette de [(200 à 1 500) mg/kg]. Cela témoigne de la fiabilité du procédé, facilitant une analyse cohérente et reproductible dans des contextes industriels. De plus, la norme exclut explicitement l'utilisation de méthodes pour les FAME dérivés de l'huile de coco et de l'huile de palmiste, en raison de la superposition des pics analytiques, ce qui ajoute une couche de clarté sur les applications appropriées de cette méthode. La norme EN 17057:2018 est particulièrement pertinente dans le cadre de l'industrie des carburants automobiles et des dérivés de graisses et huiles, où la précision dans la détermination de la composition peut avoir un impact significatif sur la qualité du produit final. En fournissant des lignes directrices claires pour l'analyse des monoglycérides saturés, cette norme contribue à un meilleur contrôle de qualité et à une conformité réglementaire, tout en assurant la sécurité des opérations grâce à un avertissement sur l'utilisation de matériaux et d'équipements pouvant être dangereux. En somme, la norme EN 17057:2018 s'affirme comme un instrument essentiel pour les professionnels du secteur cherchant à maîtriser et à garantir la qualité des carburants en relation avec les esters méthyliques d'acides gras.
SIST EN 17057:2018 표준은 자동차 연료와 지방 및 오일 유도체에서 지방산 메틸 에스터(FAME)에서 포화 단일글리세리드의 함량을 정확하게 측정하기 위한 방법을 제시합니다. 이 표준은 1-C16:0, 2-C16:0 및 1-C18:0의 세 가지 포화 단일글리세리드를 식별하고 정량하는 데 중점을 두고 있으며, 이로써 FAME 내 포화 단일글리세리드의 총 함량은 불포화 상태가 전혀 고려되지 않고 명확히 계산됩니다. 표준의 강점 중 하나는 FAME에 포함된 포화 단일글리세리드의 함량을 (200에서 1,500) mg/kg 범위에서 정밀하게 측정할 수 있다는 점입니다. 이는 포화 단일글리세리드가 FAME의 품질 및 특성을 평가하는 데 중요한 요소임을 시사하며, 따라서 이 표준은 자동차 연료의 품질 관리 및 연구에 실질적 기여를 할 수 있습니다. 그러나 이 표준은 코코넛 및 팜 커널 오일 유도체에서 생산된 FAME에 대해 적합하지 않다는 점도 명확히 명시하고 있습니다. 이는 복잡한 피크의 중첩으로 인해 정확한 측정이 어렵기 때문이며, 사용자에게 이러한 한계를 인지시키는 것이 중요합니다. 또한, 이 표준은 위험한 물질 및 장비를 사용할 수 있으므로 사용자에게 안전성을 보장하기 위한 책임을 부여합니다. 이는 표준의 적용 시 필요한 법적 및 규제 요구 사항을 충족해야 한다는 점을 상기시켜 줍니다. 결론적으로, SIST EN 17057:2018 표준은 FAME의 포화 단일글리세리드 측정에 있어 중요한 방법론을 제공하며, 자동차 연료 산업에서의 활용성이 높은 만큼 안전성을 위한 경각심도 필요합니다.
The EN 17057:2018 standard offers a well-defined methodology for determining the saturated monoglyceride content in Fatty Acid Methyl Esters (FAME), focusing specifically on 1-C16:0, 2-C16:0, and 1-C18:0 monoglycerides. The standard's precise scope highlights its reliability for products within the saturated monoglycerides concentration range of 200 to 1,500 mg/kg, which is particularly relevant for laboratories and manufacturers working with FAME. One of the significant strengths of this standard lies in its specificity, as it clearly outlines which saturated monoglycerides can be quantified, thereby providing a targeted approach to analysis. This is essential for ensuring the quality and compliance of automotive fuels derived from fats and oils, as the presence of specific monoglycerides can influence fuel performance and compatibility with various engine technologies. Furthermore, the standard delineates its limitations, specifically excluding FAME produced from or containing coconut and palm kernel oil derivatives due to potential overlapping peaks that could confound results. This clarity helps users to avoid misapplication of the standard and promotes a streamlined testing process by preventing ambiguous interpretations. The EN 17057:2018 standard also aids in fulfilling regulatory and quality assurance requirements in the automotive fuel industry, making it highly relevant for stakeholders aiming for adherence to industry standards and safety protocols. However, it is crucial to note that the standard emphasizes the need for user responsibility regarding the handling of hazardous materials involved in the testing process, underlining the importance of safety measures in laboratory practices. Overall, the EN 17057:2018 standard is a vital resource for ensuring accurate measurements of saturated monoglycerides in FAME, contributing to enhanced fuel quality assessment and compliance in the automotive sector. Its detailed methodological framework and focus on specific monoglycerides reinforce its significance in the industry.
Die Norm EN 17057:2018 bietet eine präzise Methode zur Bestimmung des Gehalts an gesättigten Monoglyceriden in Fettsäuremethylestern (FAME), insbesondere der gesättigten Monoglyceride 1-C16:0, 2-C16:0 und 1-C18:0. Die Norm legt klar fest, dass der gesamte Gehalt an gesättigten Monoglyceriden durch die Summierung dieser drei spezifischen Monoglyceride berechnet wird, was eine konsistente und zielgerichtete Analyse gewährleistet. Ein hervorzuhebendes Merkmal dieser Norm ist die definierte Genauigkeit für FAME, deren gesättigte Monoglyceride sich im Bereich von 200 bis 1.500 mg/kg befinden. Diese präzise Bestimmung ist entscheidend für die Qualitätskontrolle und -sicherung in der Branche der Automobilkraftstoffe und der Derivate von Fetten und Ölen. Die Relevanz der Norm ist besonders ausgeprägt, da sie Exaktheit und Standardisierung in einem Bereich fördert, der zunehmend durch technische Anforderungen und regulatorische Vorgaben geprägt ist. Es ist wichtig zu betonen, dass die Norm nicht für FAME geeignet ist, die aus Kokosnuss- und Palmkernölen gewonnen werden, aufgrund von Überlagerungen in den Spektraldaten. Dies zeigt die sorgfältige Abgrenzung des Anwendungsbereichs und vermindert potenzielle Verwirrung bei der Anwendung der Methode. Zusätzlich wird in der Norm ein klarer Hinweis auf die Sicherheitsbedenken gegeben, die mit der Handhabung von gefährlichen Materialien und Geräten verbunden sind. Dies unterstreicht die Verantwortung des Benutzers, geeignete Sicherheitsmaßnahmen zu ergreifen, um die Gesundheit des Personals zu gewährleisten und die gesetzlichen Anforderungen zu erfüllen. Insgesamt ist die EN 17057:2018 eine bedeutende Norm, die nicht nur technologische Präzision in der Analyse von FAME fördert, sondern auch auf die praktischen Anforderungen an Sicherheit und Verantwortlichkeit für alle Benutzer hinweist.
SIST EN 17057:2018は、自動車燃料および脂肪・油の誘導体に関する標準的な文書であり、脂肪酸メチルエステル（FAME）中の飽和モノグリセリドの含有量を測定する方法を規定しています。この標準は、特に1-C16:0、2-C16:0、および1-C18:0の飽和モノグリセリドを特定し、定量化することを目的としています。そのため、ユーザーは標準の範囲内であるこれら三つの飽和モノグリセリドの合計含有量を計算することができます。 この標準の強みは、その高い精度にあります。特に、飽和モノグリセリドの含有量が200～1,500 mg/kgの範囲内で精密な測定が可能です。また、FAMEの分析において、特定の飽和モノグリセリドのみを対象とすることで、測定作業の効率化と正確性を向上させています。 ただし、この方法は、ココナッツ油およびパームカーネルオイルから生成されたFAMEには適用できない点が注意点です。これは、異なるピークの重複により、正確な測定が難しくなるためです。この制限を理解し、他の飽和モノグリセリド（例えば1-C17:0など）が含まれる可能性があることは、試験を正確に行う上での重要な要素です。 全体として、SIST EN 17057:2018は、FAMEの検査における重要な基準であり、その適用範囲や測定の精度は、自動車燃料関連の分野における品質管理や安全性の向上に貢献します。そのため、業界内での関連性は非常に高く、研究や実務における重要な指針となることでしょう。また、標準を利用する際には、関連する安全対策を講じる必要があることを忘れてはなりません。
