“…Liquid chromatography with tandem mass spectrometric detection (LC‐MS/MS) provides the selectivity and sensitivity needed for quantitative analysis of xenobiotic compounds in complex biological matrices such as leaf tissue extracts. It is used routinely to detect residues of applied compounds (e.g., Schermerhorn et al 2) and to study compound metabolism (e.g., Onisko et al 3). A liquid chromatographic separation prior to MS/MS quantitation separates the compound of interest from matrix components that may suppress the ionization/response of the compound of interest.…”

BACKGROUND: Systemicity is an important attribute of fungicides that is difficult to measure in early-stage screening without labeling the compound with a radioisotope. A method of measuring translocation that does not require potent fungicidal activity or a radiolabel would guide identification of compounds with desirable attributes. RESULTS:The authors developed an analytical technique that mimics field application, using LC-MS/MS to screen compounds for translocation in wheat leaves. The method sorted commercial and experimental fungicides appropriately into systemic and non-systemic categories. A model using LC-MS/MS data was equivalent to a lipophilicity model and superior to a water solubility model at predicting compound systemicity.CONCLUSION: Early-stage compounds can be screened for systemicity on whole plants using LC-MS/MS.

One of the current trends of modern analytical chemistry is the miniaturization of the various tools daily used by a large number of researchers. Ultrafast separations, consumption of small amounts of both samples and reagents as well as a high sensitivity and automation are some of the most important goals desired to be achieved. For many years a large number of research laboratories and analytical instrument manufacturing companies have been investing their efforts in this field, which includes miniaturized extraction materials, sample pre‐treatment procedures and separation techniques. Among the separation techniques, capillary electromigration methods (which also include CEC), microchip and nano‐LC/capillary LC have received especial attention. Besides their well‐known advantages over other separation tools, the role of these miniaturized techniques in food analysis is still probably in an early stage. In fact, applications in this field carried out by CEC, microchip, nano‐LC and capillary LC are only a few when compared with other more established procedures such as conventional GC or HPLC. The scope of this review is to gather and discuss the different applications of such miniaturized techniques in this field. Concerning CE, microchip‐CE and CEC works, emphasis has been placed on articles published after January 2007.
