The certification of the purity of seven oxygenated polycyclic aromatic compounds CRM 337, 338, 339, 340, 341, 342, 343
The preparation and certification of batches of seven oxygenated polycyclic aromatic hydrocarbons (PAHs), possessing purities between 0.989 and 0.998 g/g (expressed as mass fractions of the principal compound), are described. Purity measurements were carried out using a variety of analytical methods - gas liquid chromatography, high performance liquid chromatography and mass spectrometry. The general aim was to certify the purity of the reference material with a total uncertainty of less than 0.01 g/g.
