“…The analyses were performed on a GCMS-QP2010 Plus gas chromatograph from Shimadzu, adapted to work as GC × GC-qMS with technology developed in our laboratory (13,(17)(18)(19)(20)(21). The home-made four-jet modulator was turned off to carry out conventional GC-qMS runs.…”

The Amazonian tree Aniba rosaeodora Ducke, whose wood provides commercial essential oil for perfumery houses, is at risk of extinction and listed by CITES. An alternative source of this oil would be to trim leaves of young plants and steam distill them to obtain the essential oil. Four-year-old plant material could provide an oil that can both be an economical source and eventually a replacement for wood oil in perfumery. A characterization of the essential oil from these leaves has been obtained by comprehensive two-dimensional gas chromatography. The two-dimensional analytical technique was able to separate and identify about three times more compounds than is the case with conventional gas chromatography, leading to a more complete essential oil chemical characterization.

This report reviews recent literature on the application of multivariate calibration techniques to both first- and second-order data, aimed at the analytical determination of analytes of interest or sample properties in a variety of industrial, pharmaceutical, food, and environmental samples, including examples of process control. The most used data processing tools are briefly described, with emphasis on the advantages that can be obtained by applying specific combinations of multivariate data and algorithms. The main focus is on works devoted to first-order data (i.e., spectra, chromatograms, etc.) combined with partial least-squares regression, which has become the standard for this type of analytical research. A brief discussion on recent work on second-order data and algorithms is also included, as this field is rapidly growing, although at present it does not show, the general applicability of the first-order counterparts.
