Although optimization was achieved by largely empirical means, a number of impressive separations of complex mixtures (petroleum products [211,214,233], essential oils [234], polychlorinated biphenyls [235], low-volatility chlorinated compounds [236] and fatty acid esters [212]) have been published. In addition, the possibility of interfacing two-dimensional comprehensive gas chromatography with time-of-flight mass spectrometry has been demonstrated [212,237]. This later combination provides a very powerful tool for target compound analysis by combining retention information on two... [Pg.223]

Another GC-MS application of considerable potential is with comprehensive gas chromatography (GC X GC). A short fast column follows a longer standard column and fractions eluting from the first column are trapped and periodically released into the second (fast) column. The second column has a stationary phase that is different from that of the first so that there is a tendency for the compounds that co-elute from the first column to separate in the second column. GC x GC requires full scan spectra for separations less than 20-30 s and TOF-MS is ideal for this speed of analysis. [Pg.2863]

In contrast to comprehensive gas chromatography (GC x GC), the number of comprehensive liquid chromatography (LC x LC) applications reported in literature are much less. It can be affirmed that LC X LC presents a greater flexibility when compared to GC x GC since the mobile phase composition can be adjusted in order to obtain enhanced resolution [132], Comprehensive HPLC systems, developed, and applied to the analysis of food matrixes, have employed the combination of either NP x RP or RP x RP separation modes. However, it is worthy of note that the two separation mechanisms exploited should be as orthogonal as possible, so that no or little correlation exists between the retention of compounds in both dimensions. [Pg.174]
