Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of phosphorus content by inductively coupled plasma (ICP) emission spectrometry

This European Standard specifies an inductively coupled plasma (ICP) emission spectrometry method for the determination of phosphorus content between 4 mg/kg and 20 mg/kg in Fatty Acid Methyl Esters, hereinafter referred as FAME.
This method aims to evaluate the FAME quality, in terms of transesterification by-products content such as phosphorus, whose concentration may affect the fuel behaviour.
WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Erzeugnisse aus pflanzlichen und tierischen Fetten und Ölen - Fettsäure-Methylester (FAME) - Bestimmung des Phosphorgehaltes durch Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP)

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Gehaltes von Phosphor mit Hilfe der Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP) im Bereich von 4 mg/kg bis 20 mg/kg in Fettsäure-Methylestern, nachfolgend als FAME bezeichnet, fest.
Die Anwendung dieses Verfahrens dient dazu, die Qualität des FAME zu beurteilen, bezüglich der aus dem Veresterungsprozess entstehenden Nebenprodukte wie Phosphor, dessen Konzentration die Kraftstoffqualität beeinflussen kann.
WARNUNG - Die Anwendung dieses Verfahrens kann den Einsatz gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm gibt nicht vor, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Der Anwender dieser Norm ist dafür verantwortlich, vorher angemessene Maßnahmen zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu ermitteln.

Produits dérivés des corps gras - Esters méthyliques d'acides gras (EMAG) - Détermination de la teneur en phosphore par spectrométrie d'émission de plasma induit par haute fréquence (méthode ICP)

La présente Norme européenne spécifie une méthode de dosage du phosphore dans les esters méthyliques d'acides gras, ci-apres appelés EMAG, par spectrométrie d'émission de plasma induit par haute fréquence a des teneurs comprises entre 4 mg/kg et 20 mg/kg.
L'objet de cette méthode est d'évaluer la qualité des EMAG en termes de teneur en sous-produits de transestérification tels que le phosphore dont la concentration peut affecter le comportement du carburant.
AVERTISSEMENT   La présente méthode peut mettre en jeu des substances, des opérations et des équipements dangereux. Elle ne prétend pas prendre en compte tous les problemes de sécurité associés a son utilisation. Il est de la responsabilité de l'utilisateur de la présente méthode de rechercher et de mettre en place les mesures appropriées de sécurité et de protection de la santé, et de déterminer l'applicabilité des dispositions faisant l'objet de la méthode avant utilisation.

Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN ISO 661, Animal and vegetable fats and oils - Preparation of test portion (ISO 661:1989).3 Terms and definitionsFor the purposes of this European Standard, the following term and definition applies.3.1phosphorus contentresidual phosphorus remaining in FAME from phospholipids after the vegetable oil transesterification reaction4 PrincipleA weighed test portion of sample is diluted in xylene. The standards are prepared from a phosphorus organiccompound dissolved in a mineral oil and diluted in a mixture of xylene and stock oil. The addition of stock oil makesit possible to reduce the differences in viscosity between samples and standards and improves their storage.The solutions are introduced in aerosol form into an inductively coupled argon plasma. The phosphorus content isdetermined by comparing the emission of the element in the solution of the test portion of the sample with theemission of the standards at the same wavelength.NOTE 1The wavelengths commonly used are 213,6 nm and 178,3 nm.The sample shall be diluted at least ten times with xylene in order to allow a proper introduction of the aerosol intothe plasma.NOTE 2Xylene may be replaced by other suitable solvents in case of instable plasma or specific laboratory safety use.SIST EN 14107:2003

Add approximately 0,3 g of stabilizer (5.4), dilute to the markwith xylene and homogenise the solution. The exact titre of this solution will be calculated and subsequently usedfor the standards. This solution may be kept during one month, if the stabilizer (5.4) is used.In case stabilizer is not used, the intermediate dilution solution of phosphorus cannot be kept.NOTEThe volumetric flasks can be replaced by disposable non calibrated flasks; in this case, the dilutions of the samplesare prepared and expressed in mass/mass instead of mass/volume.6 Apparatus6.1An inductively coupled plasma emission spectrometer equipped with the following elements :6.1.1A quartz torch.6.1.2A nebulizer (device which transforms the solution i
