Natural gas - Determination of composition with defined uncertainty by gas chromatography - Part 6: Determination of hydrogen, helium, oxygen, nitrogen, carbon dioxide and C1 to C8 hydrocarbons using three capillary columns (ISO 6974-6:2002)

ISO 6974-6:2002 describes a gas chromatographic method for the quantitative determination of the content of helium, hydrogen, oxygen, nitrogen, carbon dioxide and C1 to C8 hydrocarbons in natural gas samples using three capillary columns. This method is applicable to the determination of these gases within the mole fraction ranges varying from 0,000 1 % to 40 %, depending on the component analysed, and is commonly used for laboratory applications. However, it is only applicable to methane within the mole fraction range of 40 % to 100 %. These ranges do not represent the limits of detection, but the limits within which the stated precision of the method applies. Although one or more components in a sample may not be present at detectable levels, the method can still be applicable.
ISO 6974-6:2002 is only applicable if used in conjunction with ISO 6974-1:2000 and ISO 6974-2:2001.
This method can also be applicable to the analysis of natural gas substitutes. Additional information on the applicability of this method to the determination of natural gas substitutes is also given where relevant.

Erdgas - Bestimmung der Zusammensetzung mit definierter Unsicherheit durch Gaschromatographie - Teil 6: Bestimmung des Wasserstoffs, Heliums, Sauerstoffs, Stickstoffs, Kohlenstoffdioxids und der Kohlenwasserstoffe C1 bis C8 mit drei Kapillarsäulen (ISO 6974-6:2002)

Dieser Teil von ISO 6974 beschreibt ein gaschromatographisches Verfahren mit drei Kapillarsäulen zur
quantitativen Bestimmung des Gehalts an Wasserstoff, Helium, Sauerstoff, Stickstoff, Kohlenstoffdioxid und
C 1 - bis C 8 -Kohlenwasserstoffen in Erdgasproben. Das Verfahren gilt für die Analyse von Gasen, die Bestand-
teile mit den in Tabelle 1 angegebenen Bereichen des Stoffmengenanteils enthalten, und wird üblicherweise
für Laboranwendungen genutzt. Diese Bereiche stellen nicht die Nachweisgrenzen dar, sondern die
Grenzwerte, innerhalb denen die für das Verfahren angegebene Präzision gilt. Auch wenn ein oder mehrere
Komponenten in einer Probe nicht mit nachweisbaren Konzentrationsniveaus vorliegen, kann das Verfahren
trotzdem angewendet werden.
Dieser Teil von ISO 6974 gilt nur in Verbindung mit den Teilen 1 und 2 von ISO 6974.
Dieses Verfahren kann auch für die Analyse von Erdgasaustauschgasen angewendet werden.
ANMERKUNG Zusätzliche Informationen über die Anwendbarkeit dieses Verfahrens zur Bestimmung von Erdgasaus-
tauschgasen werden an relevanter Stelle ebenfalls gegeben.

L'ISO 6974-6:2002 décrit une méthode par chromatographie en phase gazeuse pour la détermination quantitative des teneurs en hydrogène, hélium, oxygène, azote, dioxyde de carbone et hydrocarbures C1 à C8 d'échantillons de gaz naturel, en utilisant trois colonnes capillaires. Elle est applicable à l'analyse de gaz contenant des constituants dont la fraction molaire est comprise dans les intervalles donnés dans le Tableau 1, et elle est couramment mise en oeuvre en laboratoire. Ces intervalles ne représentent pas les limites de détection, mais les limites dans lesquelles la fidélité fixée par la méthode s'applique. Bien qu'un ou plusieurs composants d'un échantillon puissent ne pas être présents à des teneurs détectables, la méthode reste applicable.
L'ISO 6974-6:2002 n'est applicable que si elle est utilisée conjointement avec les parties 1 et 2 de l'ISO 6974.
L'ISO 6974-6:2002 peut également être applicable à l'analyse des substituts du gaz naturel.
