Standard Test Method for Determination of Chemical Species in Marine Fuel Oil by Multidimensional Gas Chromatography – Mass Spectrometry
1.1 This test method covers the quantitative determination of a variety of chemical species in marine fuel oil (bunker fuel oil) by gas chromatography – mass spectrometry. By using the same conditions and by selecting required mass spectral selected ions, the test method may be used for the determination of other species than those for which precision statements and limits of detection have been established.
1.2 An example list of chemical species for which a limit of quantification has been determined by means of this test method is given in Table 1.
| Limit of Quantitation |
n-butyl alcohol | 10 |
Cyclohexanol | 10 |
n-butyl ether | 10 |
n-butyl acylate | 10 |
Styrene | 10 |
alpha-pinene | 10 |
Phenol | 20 |
alpha-methyl styrene | 10 |
beta-pinene | 10 |
4-methyl styrene | 10 |
trans-B-methyl styrene | 10 |
3-methyl styrene | 10 |
2-methyl styrene | 10 |
Dicyclopentadiene | 10 |
Limonene | 10 |
Indene | 20 |
1-phenyl ethanol | 20 |
para, alpha-Dimethyl styrene | 20 |
2,5 dimethyl styrene | 20 |
2,4 dimethyl styrene | 20 |
2-phenyl ethanol (phenylethanol) | 20 |
2-Ethyl Phenol | 50 |
2,4 Dimethyl Phenol | 20 |
4-Ethyl Phenol (co elutes with 3-ethylphenol) | 20 |
2-Phenoxy-1-propanol | 50 |
2-Phenoxy ethanol | 50 |
4-isopropylphenol | 50 |
1-Phenoxy-2-Propanol | 20 |
Styrene Glycol | 50 |
1.3 Other refinery hydrocarbon fractions and their mixtures may be tested using the same test method conditions. However, the precision of this test method reflects the compounds in Table 1.
1.4 Results are reported to the nearest 1.0 mg/kg.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, 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.
