Environmental Solid Matrices - Determination of hydrocarbon content in the range of C10 to C40 by gas chromatography (ISO/DIS 16703:2024)
ISO 16703:2004 specifies a method for the quantitative determination of the mineral oil (hydrocarbon) content in field-moist soil samples by gas chromatography.
The method is applicable to mineral oil contents (mass fraction) between 100 mg/kg and 10 000 mg/kg soil, expressed as dry matter, and can be adapted to lower detection limits.
ISO 16703:2004 is applicable to the determination of all hydrocarbons with a boiling range of 175 °C to 525 °C, n-alkanes from C10H22 to C40H82, isoalkanes, cycloalkanes, alkylbenzenes, alkylnaphthalenes and polycyclic aromatic compounds, provided that they are not absorbed on the specified column during the clean-up procedure.
ISO 16703:2004 is not applicable to the quantitative determination of hydrocarbons < C10 originating from gasolines.
On the basis of the peak pattern of the gas chromatogram obtained, and of the boiling points of the individual n-alkanes listed in Annex B, the approximate boiling range of the mineral oil and some qualitative information on the composition of the contamination can be achieved.

Matrices solides environnementales - Dosage des hydrocarbures de C10 à C40 par chromatographie en phase gazeuse (ISO/DIS 16703:2024)
L'ISO 16703:2004 spécifie une méthode de dosage quantitatif par chromatographie en phase gazeuse des huiles minérales (hydrocarbures) contenues dans des échantillons de sol bruts.
La méthode est applicable à des teneurs en huiles minérales (fraction massique) comprises entre 100 mg/kg et 10 000 mg/kg de sol, exprimées sous forme de matière sèche, et peut être adaptée à des limites inférieures de détection.
L'ISO 16703:2004 est applicable au dosage de tous les hydrocarbures ayant un domaine d'ébullition compris entre 175 °C et 525 °C, des n-alcanes entre C10H22 et C40H82, des isoalcanes, des cycloalcanes, des alkylbenzènes, des alkylnaphtalènes et des composés aromatiques polycycliques, à condition qu'ils ne soient pas absorbés sur la colonne spécifiée pendant l'étape de purification.
L'ISO 16703:2004 n'est pas applicable au dosage quantitatif des hydrocarbures < C10 provenant des essences.
Compte tenu de la forme des pics du chromatogramme en phase gazeuse obtenu et du point d'ébullition des différents n-alcanes indiqués à l'Annexe B, il est possible de déterminer le domaine d'ébullition approximatif des huiles minérales et d'obtenir quelques informations qualitatives sur la composition des polluants.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

1 Scope
This International Standard specifies a method for the quantitative determination of the mineral oil
(hydrocarbon) (C to C ) content in soil and waste samples by gas chromatography.
10 40
The method is applicable to mineral oil contents (mass fraction) between 100 mg/kg and 10 000 mg/kg soil,
expressed as dry matter, and can be adapted to lower limits of detection.
Using this standard all hydrocarbons with a boiling range of approximately 175 °C to 525 °C, e.g. n-alkanes
from C H to C H , isoalkanes, cycloalkanes, alkyl benzenes, alkyl naphthalenes and polycyclic aromatic
10 22 40 82
compounds are determined as hydrocarbons, provided they do not adsorb on the Florisil column during
clean-up.
The standard can also be applied to determine any fraction in-between the range n-C to n-C .

Volatile hydrocarbons cannot be quantitatively determined using this standard. This will affect the
determination of some common hydrocarbon fue
