Fat and oil derivatives - Fatty Acid Methyl Esters - Determination of methanol content

This European Standard specifies a method for the determination of methanol content in fatty acid methyl esters (FAME) for use as diesel fuel and domestic heating fuel. The method is applicable for a concentration range from 0,01 % to 0,5 % (m/m) methanol. The method is not applicable to mixtures of FAME which contain other low boiling components.

1 Scope

This document specifies a method for the determination of the methanol content of fatty acid methyl

esters (FAME) for use as diesel fuel and domestic heating fuel. The method is applicable to methanol

contents between 0,01 % (m/m) and 0,5 % (m/m). The method is not applicable to mixtures of FAME

containing other low boiling components.

NOTE 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.

WARNING — The use of this document can involve hazardous materials, operations and equipment. This

document does not purport to address all of the safety problems associated with its use. It is the

responsibility of users of this document 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.

3 Terms and definitions
No terms and definitions are listed in this document.

4 Principle

The sample is heated at 80 °C in a hermetically sealed vial to allow desorption of contained methanol into

the gas phase. When the equilibrium is reached a defined part of the gas phase is injected into a gas

chromatograph, where methanol is detected with a flame ionization detector.

The amount of methanol can be determined either by internal calibration (procedure A) or by external

calibration (procedure B).

If only manual equipment is available then only internal standard calibration should be used.

5 Reagents
Use only reagents of recognized analytical grade, unless otherwise specified.
5.1 Methanol, of known purity greater than 99,5 %.

5.2 2-propanol, of known purity, greater than 99,5 % (for procedure A, internal calibration).

5.3 Reference FAME, with a methanol content less than 0,001 % (m/m).

Reference FAME can either be obtained from commercial sources or by washing FAME three to five times

with distilled water in a separator funnel. FAME should be then dried by heating at 90 °C under stirring

and reduced pressure.
5.4 Carrier gas, nitrogen, helium or hydrogen, of know purity greater than 99 %.
6 Apparatus
6.1 Head space vials, 20 ml capacity.
6.2 Inert septa (e.g. TFE or Viton ) and metallic caps.
6.3 Syringe, 10 µl, accurate to 0,1 µl.
6.4 Gas syringe 500 µl, fitted with a valve (for manual procedure).
6.5 Crimping pliers.
6.6 Pipettes, of 1 ml, 2 ml, 5 ml capacity.
6.7 Volumetric flasks, capacity 10 ml and 25 ml.

6.8 Gas chromatograph, equipped with a capillary column, suitable injector (automatic headspace

system or a split/splitless injector) and flame ionization detector, integrator.

6.9 Capillary column, the column shall elute methanol as a symmetrical peak. Stationary phases like

2) 2) 2) 2)

methylpolysiloxane (e.g. DB1 , SE30 ) or polyethylenglycol (e.g. DBWAX , CARBOWAX ) can be

used successfully and a film thickness of minimum 0,5 µm is recommended.

The use of a packed column equipped by one of the above mentioned stationary phases or of Chromosorb

101 is also allowed.
6.10 Automatic headspace equipment

The automatic headspace equipment used shall have an accuracy of 1 % or better concerning

experimental conditions like equilibrium temperatur
