Liquid petroleum products - Determination of hydrocarbon types and oxygenates via multidimensional gas chromatography method - Round Robin research report
This Technical Report presents the study on the application of EN 14517 [2] to other oxygenates. This report supports an extension of the scope of the method, which has been explicitly requested by ISO/TC 28 at the time of revision of EN 14517 and was agreed to result in the parallel Standard EN ISO 22854 [3].
This Technical Report is published as background information to judge the approval of the use of the method for the determination of all oxygenates as mentioned in the European Fuels Directive. This Technical Report should also support the use of multidimensional chromatography as the method for disputes on oxygenates in EN 228 [1].
NOTE For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction.

Foreword
This document (CEN/TR 15475:2015) has been prepared by Technical Committee CEN/TC 19 “Gaseous and
liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat of
which is held by NEN.

The second edition of this document includes Round Robin data generated in 2012 that led to revision of
EN ISO 22854.
Introduction
1)
In 2004, the company AC Analytical Controls conducted a Performance Monitoring Program on the AC
Reformulyzer™. This is a kind of crosscheck program where customers analyse samples distributed by the
company and then report the analysis results. The company checks the analytical performance of the
instruments, keeping in mind the possible analytical errors that can occur. Because raw data are reported
(chromatogram and data for each carbon number/group), a detailed review can be made. The company
informs a customer when the instrument performance is inadequate and where possible provides information
and instructions to improve the performance.
The intention was to get a precision statement for oxygenates that were not included in EN 14517 [2], but that
are listed in EN 228. Besides this, the performance for other properties (aromatics, olefins, benzene) has been
determined.
More information on the review of the data is available from the monitoring, but this technical report focuses
on oxygenates. Results for other properties (aromatics, olefins, benzene) are listed in the tables but are not
discussed in detail here. Also the evaluation for outliers is done on oxygenates only, not on the other
properties.
The precision data obtained from this program were used to develop the EN ISO 22854 method which was
published in 2008 [3].
In 2010 another Round Robin was organized to establish a test method to determine the oxygenated
components in ethanol automotive fuel (E85). Components such as ethers, C3-C5 alcohols and ethanol could
be made part of an E85 specification.
Four methods were tested:
A. EN ISO 22854 modified (with sample dilution)
B. EN 1601 modified (with sample dilution)
C. Capillary column method (2 columns in series, UNGDA method)
D. Capillary column method (2 separate columns, Suedzucker method)
Only method A with sample dilution had enough participants to derive a precision statement. The dilution step
was needed to lower the ethanol content in the sample to values below 20 % (V/V).
The Round Robin was carried out by TC 19/WG 9 and the results were evaluated conform EN ISO 4259. As
methods B, C and D did not get enough participants a 2nd ILS was carried out to see if more data could be
obtained for these methods. The details of these Round Robin Tests are added as Appendix A and B to this
Research Report.
