Automotive fuels - Determination of methanol in automotive ethanol (E85) fuel by gas chromatography - Part 2: Method using heart cut technique
This European Standard specifies a determination method of methanol in E85 automotive fuel by capillary gas chromatography using heart cutting and flame ionisation detection. The standard is applicable to fuels having a methanol content from about 0,5 to about 1,6 % (V/V). The method is applicable in a wider range, from about 0.1% to about 2.2 % (V/V), but precision was not established over this full range.

EN 16761-2:2015 (E) 3 European foreword This document (EN 16761-2:2015) 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. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2016, and conflicting national standards shall be withdrawn at the latest by June 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. The determination of a significant amount of methanol in ethanol (E85) automotive fuels was deemed to be necessary to check the product for compliance against EU emission regulations. The CEN/TC 19 Ethanol Fuels Task Force requested the development of such a determination technique. In EN 16761, Automotive fuels — Determination of methanol in automotive ethanol (E85) fuel by gas chromatography, two test methods were developed that comply with this scope: — Part 1: Method using single column technique; — Part 2: Method using heart cut technique [the present document]. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom SIST EN 16761-2:2016
EN 16761-2:2015 (E) 4 1 Scope This European Standard specifies a determination method of methanol in automotive ethanol (E85) fuel (also designated as ethanol (E85) automotive fuel or shortly "E85") by capillary gas chromatography using heart cutting technique. Fuel quality specifications for this product exist, see Bibliography Entry [1]. This standard is applicable to fuels having a methanol content from about 0,5 % (V/V) to about 1,5 % (V/V). Other methanol contents can also be determined, however no precision data for results outside the specified range is available. NOTE For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, . WARNING — The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 16761-2:2015 (E) 5 Note 1 to entry: Figure 6 shows an example of a sample chromatogram. 4 Principle This standard describes the analysis of methanol content in automotive ethanol (E85) fuels using the heart cut technique. The analyser is based upon the principle described by D.R. Deans [3]. This technique controls the pressure between two columns and directs the effluent of a (pre) column to usually two columns, an analytical column and a monitor column. By using columns of a very different nature as pre column and analytical column (e.g. a non-polar and a polar column) separations can be achieved that are difficult to obtain using a single column. This allows the analysis of methanol to be independent of any impurities or high boiling material that may be present in the sample. The method uses external standard calibration. The sample is injected onto a methyl silicone pre column which elutes the methanol and part of the ethanol plus any light hydrocarbons to the analytical column (Figure 1). After methanol has fully eluted onto the analytical column, the valve and thus a Pressure Control Module (PCM) pressure is switched and the components coming from the pre column are
