Capillary gas chromatography of linear alkenes on squalane

Determination of polycyclic aromatic hydrocarbons in atmospheric particulate matter by high pressure liquid chromatography coupled with fluorescence techniques

“…High pressure liquid chromatography (hplc) is a particularly promising technique for the separation of high molecular weight PAH (16,(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55). The advantages of hplc have been greatly enhanced by the recent development of bonded octadecylsilyl columns of micro particle size (56)(57)(58).…”

Method of Determination of Emission Properties of Very Weakly Emitting Species Ensuring Elimination of Emission of Impurities

“…Only a few authors have reported the uncorrected ES or EES along with chromatograms. [40][41][42][43][44][45] The use of a fluorescence detector in conjunction with an HPLC system used for the identification of the separated components was described in the review paper by Smalley and McGown. 46 However, we have not found any papers whose authors have used the corrected ES and EES and U E measured after chromatographic separation in order to determine photophysical and photochemical properties of the compounds studied.…”

Calculation of Abraham model L-descriptor and standard molar enthalpies of vaporization for linear C7-C14 alkynes from gas chromatographic retention index data

“…using the measured Kovats retention indices, RI, for those alkane, alkene, and alkynes solutes for which we already have a complete set of solute descriptors. In order to have a sufficient number of experimental data points to establish meaningful Abraham model correlations we augmented the retention index datasets for the squalane and apiezon L stationary phases with experimental values determined by Sojak et al 59 for linear C6-C14 alkenes on a squalane stationary phase, and with experimental values determined by Vigdergauz et al 60 and Sojak et al 61 for several miscellaneous organic compounds on an apiezon L stationary phase. In total we had 100 and 44 experimental data points to use in the regression analyses for constructing the Abraham model correlations for the squalane and apiezon L stationary phases, respectively.…”
