BS EN 13132:2000 – Methods of test for petroleum and its products Ð BS 2000-466: Liquid petroleum products Ð Unleaded petrol Ð Determination of organic oxygenate compounds and total organically bound oxygen content by gas chromatography using column switching (Identical with IP 466/2001)

1 Scope This European Standard specifes a gas chromatographic method using column switching for the quantitative determination of individual organic oxygenate compounds in the range 0,17 % (m/m) to 15 % (m/m) and total organically bound oxygen up 3,7 % (m/m) in unleaded petrol having a final boiling point not greater than 220 °C.
NOTE 1 The final boiling point can be measured by using prEN ISO 3405:1998 1 NOTE 2 Fur the purposes of this European Standard, the terms“% (m/m)” and“% (VV)” are used to represent respectively the mass fraction and the volume fraction.
This European Standard is applicable to the determination of oxygen-containing compounds and total organically bound oxygen in unleaded petrol in line with the relevant EU Directives2 . 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 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
These nomative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
3 Principle
Oxygen containing organic compounds are isolated from the sample using a first capillary column.
In a second capillary column the oxygen containing organic compounds are separated, and detected individually using a flame ionization detector.
NOTE Guidance on the column switching technique is given in annex B.
4 Reagents and materials
Use only reagents of recognized analytical grade and water conforming to grade 3 of EN ISO 3696.
4.1 Carrier gas
Hydrogen, helium, or nitrogen, free of hydrocarbons.
WARNING Hydrogen is explosive when mixed with air at concentrations ranging approximately from 4 % (WV) to 75 % (WV). AI joints and lines carying hydrogen shall be made gas tight to prevent leakage of hydrogen into a confined space.
