“…resolution for some critical pairs such as Phen/Ant and IcdP/DahA, although poor resolution of the benzofluoranthene isomers is reported [4]. The latter is overcome by the use of a more polar stationary phase such as 50% phenyl methyl polysiloxane (i. e. DB-17MS type columns) [9,10]. Liquid-crystalline columns have also been reported to provide satisfactory separation of critical pairs that coelute on DB-5 type capillary columns such as Chr and triphenylene, the benzofluoranthene isomers and dibenz[a,c]anthracene (DacA) and DahA [4,11].…”

“…This stationary phase provides good separation of certain pairs (i. e. phenanthrene and anthracene), although critical coelutions such as that involving the benzofluoranthene isomers might be more challenging. Medium polar stationary phases such as 50% phenyl polysiloxane columns have been reported to provide satisfactory resolution of several critical pairs, including the benzofluoranthene and the dibenzoanthracene isomers, pointing to this stationary phase as a good choice for PAHs separation [4,9,10]. Liquid crystalline stationary phases have been also described to be well suited for the separation of PAHs isomers [4,11,12].…”

European legislation has recently established a list of 15 priority polycyclic aromatic hydrocarbons (PAHs) to be monitored in foodstuff. Thus, the accurate determination of these compounds has become a highly relevant issue. The fact that some of these European Union (EU) PAHs differ from those typically analysed, requires the re-evaluation of the instrumental conditions for the proper determination of the new target compounds. In this study, the influence of the stationary phase and dimensions of the GC capillary column on the chromatographic resolution of the 15 EU PAHs has been investigated. Apolar (DB-5 type) and medium polar (DB-17 type) stationary phases with different lengths and film thickness have been evaluated for the separation of the target compounds, with special emphasis on those coelutions involving isomers such as the three benzofluoranthenes included in the EU PAHs. In addition, the influence of the injection technique and the column dimensions on the recovery of the high molecular mass PAHs has been studied. A programmable temperature vaporising (PTV) injector has been used in three different operational modes and the results were compared to those obtained using on-column injection. The experimental parameters involved in the injection step were optimised by using experimental design.

“…In characterizing samples with higher masses and more limited volatilities, however, liquid-phase separations such as high performance liquid chromatography (HPLC) tend to be more useful. Both normal and reverse phase HPLC of polycyclic aromatic hydrocarbon compounds (PAH) are well understood, − particularly in relation to the influence of solute shape and configuration on retention times. However, HPLC analyses are limited by the lack of solvents able to elute large PAH molecules with molecular masses much above 500 u from a bonded silica-particle column. , The limited availability of well-defined standard compounds over a wide range of masses has also tended to restrict the amount of information that can be obtained from HPLC studies above the 500 u level.…”

Analysis of polycyclic aromatic hydrocarbons (PAHs) in environmental samples: a critical review of gas chromatographic (GC) methods

et al. 2006

Polycyclic aromatic hydrocarbons (PAHs) are frequently measured in the atmosphere for air quality assessment, in biological tissues for health-effects monitoring, in sediments and mollusks for environmental monitoring, and in foodstuffs for safety reasons. In contemporary analysis of these complex matrices, gas chromatography (GC), rather than liquid chromatography (LC), is often the preferred approach for separation, identification, and quantification of PAHs, largely because GC generally affords greater selectivity, resolution, and sensitivity than LC. This article reviews modern-day GC and state-of-the-art GC techniques used for the determination of PAHs in environmental samples. Standard test methods are discussed. GC separations of PAHs on a variety of capillary columns are examined, and the properties and uses of selected mass spectrometric (MS) techniques are presented. PAH literature on GC with MS techniques, including chemical ionization, ion-trap MS, time-of-flight MS (TOF-MS), and isotope-ratio mass spectrometry (IRMS), is reviewed. Enhancements to GC, for example large-volume injection, thermal desorption, fast GC, and coupling of GC to LC, are also discussed with regard to the determination of PAHs in an effort to demonstrate the vigor and robustness GC continues to achieve in the analytical sciences.
