Petroleum products and related materials - Determination of hydrocarbon types - Fluorescent indicator adsorption method
This European Standard specifies a fluorescent indicator adsorption method for the determination of hydrocarbon types over the concentration ranges from 5 % (V/V) to 99 % (V/V) aromatic hydrocarbons, 0,3 % (V/V) to 55 % (V/V) olefins, and 1 % (V/V) to 95 % (V/V) saturated hydrocarbons in petroleum fractions that distil below 315 ºC. This method may apply to concentrations outside these ranges, but the precision has not been determined.
When samples containing oxygenated blending components are analysed, the hydrocarbon type results can be reported on an oxygenate-free basis or, when the oxygenate content is known, the results can be corrected to a total-sample basis.
This test method is for use with full boiling range products. Cooperative data have established that the precision statement does not apply to petroleum fractions with narrow boiling ranges near the 315 °C limit. Such samples are not eluted properly, and results are erratic.
Samples containing dark-coloured components that interfere with reading the chromatographic bands cannot be analysed.
NOTE 1 The oxygenated blending components methanol, ethanol, tert-butyl methyl ether (MTBE), methyl tert-pentyl ether (TAME) and tert-butyl ethyl ether (ETBE) do not interfere with the determination of hydrocarbon types at concentrations normally found in commercial petroleum blends. These oxygenated compounds are not detected since they elute with the alcohol desorbent. The effects of other oxygenated compounds should be individually verified.
NOTE 2 For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
WARNING — The use of this European Standard may involve hazardous materials, operations and equipment. This European 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 establish appropriate safety and health practices
Mineralölerzeugnisse und verwandte Produkte - Bestimmung der Kohlenwasserstofftypen - Adsorptionsverfahren mit Fluoreszenz-Indikator
Dieses Dokument legt ein Adsorptionsverfahren mit Fluoreszenz-Indikator fest für die Bestimmung der nachfolgend genannten Kohlenwasserstofftypen in Mineralölfraktionen, die unterhalb von 315 °C sieden, und zwar für aromatische Kohlenwasserstoffe im Bereich von 5 % (V/V) bis 99 % (V/V), für olefinische Kohlenwasserstoffe im Bereich von 0,3 % (V/V) bis 55 % (V/V) und für gesättigte Kohlenwasserstoffe im Bereich von 1 % (V/V) bis 95 % (V/V). Dieses Prüfverfahren kann auch auf Konzentrationen außerhalb der angegebenen Bereiche angewendet werden, jedoch ist dafür keine Präzision bestimmt worden.
Wenn Proben, die sauerstoffhaltige Blendkomponenten enthalten, analysiert werden, können die Kohlenwasserstofftypen auf „sauerstofffreier“ Basis angegeben werden, oder, wenn der Gehalt an sauerstoffhaltigen Verbindungen bekannt ist, auch nach entsprechend korrigierter Umrechnung mit Bezug auf die Gesamtprobe.
Dieses Prüfverfahren ist auf Produkte im gesamten angegebenen Siedebereich anwendbar. Untersuchungen haben gezeigt, dass die Präzisionsangaben nicht gelten für engsiedende Mineralölfraktionen nahe der angegebenen Grenze von 315 °C. Solche Proben werden nicht ordnungsgemäß eluiert und führen daher zu fehlerhaften Ergebnissen.
Es gilt nicht für Proben, die dunkel gefärbte Komponenten enthalten, welche die Auswertung der chromatographischen Zonen stören, und nicht untersucht werden können.
ANMERKUNG 1 Die sauerstoffhaltigen Blendkomponenten Methanol, Ethanol, tert-Butylmethylether (MTBE), Methyl tert pentylether (TAME, tert-Amylmethylether) und tert-Butylethylether (ETBE) stören mit für kommerzielle Mineralölmischungen üblichen Gehalten die Bestimmung nicht. Diese sauerstoffhaltigen Verbindungen werden nicht erfasst, weil sie zusammen mit dem alkoholischen Desorptionsmittel eluieren. Die Einflüsse anderer sauerstoffhaltiger Verbindungen werden im Einzelfall geprüft.
ANMERKUNG 2 Für die Zwecke dieses Dokuments wird zur Angabe des Massenanteils einer Substanz der Ausdruck „% (m/m)“ und für den Volumenanteil einer Substanz der Ausdruck „% (V/V)“ verwendet.
WARNUNG — Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Es liegt in der Verantwortung des Anwenders dieses Dokuments geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz zu ergreifen, und die Geltung weiterer diesbezüglicher Auflagen zu prüfen.
Produits pétroliers et produits connexes - Détermination des groupes d'hydrocarbures - Méthode par adsorption en présence d'indicateur fluorescent
Le présent document spécifie une méthode d’adsorption en présence d’indicateur fluorescent visant à déterminer les groupes d’hydrocarbures sur des plages de concentration comprises entre 5 % (V/V) et 99 % (V/V) pour les hydrocarbures aromatiques, entre 0,3 % (V/V) et 55 % (V/V) pour les oléfines, et entre 1 % (V/V) et 95 % (V/V) pour les hydrocarbures saturés dans des fractions pétrolières distillant en dessous de 315 ºC. La présente méthode peut être applicable à des concentrations en dehors de ces plages, mais la fidélité n’a pas été déterminée.
Lorsque des échantillons contenant des composés oxygénés sont analysés, les résultats de groupes d’hydrocarbures peuvent être notés sans tenir compte des composés oxygénés ou, lorsque la teneur en oxygénés est connue, les résultats peuvent être corrigés sur la base de l’échantillon total.
La présente méthode d’essai est destinée à être utilisée avec des produits à plage d’ébullition large. Des données communes ont établi que la déclaration de fidélité ne s’applique pas aux fractions de pétrole à plage d’ébullition étroite avoisinant le seuil de 315 °C. Ces échantillons ne sont pas correctement élués, ce qui conduit à des résultats erronés.
Les échantillons qui contiennent des composants de couleur foncée pouvant affecter la lecture des bandes chromatographiques ne peuvent pas être analysés.
NOTE 1 Les composés oxygénés comme le méthanol, l’éthanol, le méthyl tertio-butyl éther (MTBE), le méthyl tertio-pentyl éther (TAME) et l’éthyl-tertio-butyl éther (ETBE) n’affectent pas la détermination des groupes d’hydrocarbures aux concentrations habituellement trouvées dans les mélanges commerciaux de produits pétroliers disponibles. Ces composés oxygénés ne sont pas détectés puisqu’ils éluent avec l’alcool de désorption. Les effets des autres composés oxygénés sont vérifiés individuellement.
NOTE 2 Pour les besoins du présent document, les termes “% (m/m)” et “% (V/V)” sont utilisés pour représenter respectivement la fraction massique et la fraction volumique.
AVERTISSEMENT — L’utilisation du présent document peut impliquer des produits, opérations et équipements à caractère dangereux. Le présent document n’a pas la prétention d’aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de l’utilisateur de ce document d’établir des règles de sécurité et d’hygiène appropriées et de déterminer l’applicabilité des restrictions réglementaires avant son utilisation.
Naftni proizvodi in sorodni materiali - Določevanje vrste ogljikovodikov - Adsorpcijska metoda s fluorescenčnim indikatorjem
Ta evropski standard določa adsorpcijsko metodo s fluorescenčnim indikatorjem za določevanje vrst ogljikovodikov v razponu koncentracij od 5 % (V/V) do 99 % (V/V) aromatskih ogljikovodikov, od 0,3 % (V/V) do 55 % (V/V) olefinov in od 1 % (V/V) do 95 % (V/V) nasičenih ogljikovodikov v frakcijah nafte, ki se destilirajo pod 315 °C. Ta metoda se lahko uporablja za koncentracije zunaj teh razponov, vendar natančnost za njih ni bila določena.
Pri analizi vzorcev, ki vsebujejo oksigenirane mešalne komponente, je mogoče poročati o rezultatih vrste ogljikovodikov brez oksigenatov ali pa je mogoče ob zaznani vsebnosti oksigenatov rezultate popraviti na podlagi celotnega vzorca.
Ta preskusna metoda je primerna za uporabo pri proizvodih s polnim vreliščem. Skupni podatki so pokazali, da izjava o natančnosti ne velja za frakcije nafte z ozkim razponom vrelišča blizu meje 315 °C. Takšni vzorci niso pravilno eluirani in rezultati so nepravilni.
Vzorcev, ki vsebujejo temno obarvane komponente, ki ovirajo branje kromatografskih pasov, ni mogoče analizirati.
OPOMBA 1: Komponente za mešanje s kisikom metanol, etanol, terc-butil metil eter (MTBE), metil terc-pentil eter (TAME) in terc-butil etil eter (ETBE) ne vplivajo na določevanje vrst ogljikovodikov pri koncentracijah, ki jih običajno najdemo v komercialnih naftnih mešanicah. Teh oksigeniranih spojin ne zaznamo, ker se eluirajo z alkoholnim desorbentom. Učinke drugih oksigeniranih spojin naj bi preverili posamično.
OPOMBA 2: V tem evropskem standardu sta uporabljeni oznaki »% (m/m)« in »% (V/V)«, ki predstavljata masni oziroma prostorninski delež.
OPOZORILO: Pri uporabi tega standarda so lahko prisotni nevarni materiali, postopki in oprema. Ta evropski standard ne obravnava vseh varnostnih težav, ki se navezujejo na njegovo uporabo. Uporabnik tega standarda mora poskrbeti za vzpostavitev ustreznih varnostnih in zdravstvenih praks.

1 Scope
This document specifies a fluorescent indicator adsorption method for the determination of
hydrocarbon types over the concentration ranges from 5 % (V/V) to 99 % (V/V) aromatic
hydrocarbons, 0,3 % (V/V) to 55 % (V/V) olefins, and 1 % (V/V) to 95 % (V/V) saturated hydrocarbons
in petroleum fractions that distil below 315 °C. This method can apply to concentrations outside these
ranges, but the precision has not been determined.
When samples containing oxygenated blending components are analysed, the hydrocarbon type results
can be reported on an oxygenate-free basis or, when the oxygenate content is known, the results can be
corrected to a total-sample basis.
This test method is applicable to full boiling range products. Cooperative data have established that the
precision statement does not apply to petroleum fractions with narrow boiling ranges near the 315 °C
limit. Such samples are not eluted properly, and results are erratic.
It does not apply to samples containing dark-coloured components that interfere with reading the
chromatographic bands that cannot be analysed.
NOTE 1 The oxygenated blending components methanol, ethanol, tert-butyl methyl ether (MTBE), methyl tert-
pentyl ether (TAME) and tert-butyl ethyl ether (ETBE) do not interfere with the determination of hydrocarbon
types at concentrations normally found in commercial petroleum blends. These oxygenated compounds are not
detected since they elute with the alcohol desorbent. The effects of other oxygenated compounds are individually
verified.
NOTE 2 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent
respectively the mass fraction and the volume fraction.

4 Principle
Approximately 0,75 ml of sample is introduced into a special glass adsorption column packed with
activated silica gel. A small layer of the silica gel contains a mixture of fluorescent dyes. When all the
sample has been adsorbed onto the gel, alcohol is added to desorb the sample down the column. The
hydrocarbons are separated, according to their adsorption affinities, into aromatics, olefins and
saturates. The fluorescent dyes are also separated selectively with the hydrocarbon types, and render
the boundaries of the aromatic, olefin and saturate zones visible under ultraviolet light. The volume
percentage of each hydrocarbon type is calculated from the length of each zone in the column.
NOTE See NOTE 1 under Clause 1 for hydrocarbons that the described method cannot measure.
5 Reagents and materials
Use only chemicals and reagents of recognized analytical grade and water conforming to grade 3 of
EN ISO 3696.
5.1 Silica gel, manufactured to conform to the specifications given in Annex A.
