“…Enantioselective on-line LC-GC multidimensional approaches [205] are more straightforward. The enantiomeric ratios of linalool in orange and lemon oils were analyzed with a fully automated on-line LC-GC system to evaluate their genuineness, quality, and origin [206,207].…”

“…In LC-GC preseparation on a LC column is performed before GC analysis. On-line coupling LC-GC is a technique that combines the high separation efficiency of LC for sample preparation, avoiding and replacing the subsequent clean up steps, with the good performance of capillary gas chromatography separation [16][17][18][19]. It permits the elimination of practically all manual work, allowing one person to run a large number of samples in a short time.…”

An automated method for the direct analysis of polychlorinated biphenyls (PCBs) in transformer oil is presented. The proposed method uses the TOTAD (through oven transfer adsorption desorption) interface for the on-line coupling of reversed phase liquid chromatography and gas chromatography (RPLC-GC). In this fully automated system, the oil is injected directly with no sample pre-treatment step other than dilution with n-propanol and filtration. In the LC step, PCBs are separated from other components of the oils using methanol/water (90:10 v/v) as mobile phase, at a flow rate of 1 mL min À1 . The LC fraction containing the PCBs is automatically transferred to the GC by the TOTAD interface and GC analysis enables the separation of the PCB congeners. The proposed method is compared with two other methods: the European Norm (UNE-EN-61619) and that of the American Society for Testing and Materials (ASTM) (D4059-00). The proposed method practically eliminates the time-consuming sample preparation step and avoids errors caused by sample manipulation. The total PCB concentrations obtained with the three methods are similar.

“…In this respect, the use of multidimensional techniques for food analysis has been mostly focused on multidimensional gas chromatography [7][8][9] and, to a far lesser extent, on the on-line coupling of high-performance liquid-chromatography (LC) with gas chromatography (GC) using normal phase in the pre-separation step [10][11][12]. Nonetheless, it is necessary to take into account that a very high percentage of LC separations are performed by reversed phase LC (RPLC) as the employment of hydrophobic packing materials and aqueous mobile phases enlarges the range of compounds which can be analysed.…”
