“…Zhao et al [165] described experiments aiming at the biological degradation of sulfonated dyes by rot fungi. Five pesticides were analyzed by Takeda et al [166] using a CE-MS method. Their procedure involved online sample preconcentration taking advantage of a transient isotachophoretic effect.…”

“…The eluate was filtrated using a 0.22 μm filter (Millipore Corp., Bedford, MA, USA). The organic solvent was then evaporated to 9 dryness at 40ºC using a Rotavapor R-200 (from Büchi Labortechnik, Flawil, Switzerland). The residue was dissolved in 1 mL acetonitrile and directly injected in the CE instrument.…”

In this work, the determination of a group of triazolopyrimidine sulfoanilide herbicides (cloransulam-methyl, metosulam, flumetsulam, florasulam and diclosulam) in soy milk by capillary electrophoresis-mass spectrometry (CE-MS) is presented. The main electrospray interface (ESI) parameters (nebulizer pressure, dry gas flow rate, dry gas temperature and composition of the sheath liquid) are optimized using a central composite design. To increase the sensitivity of the CE-MS method, an off-line sample preconcentration procedure based on solid-phase extraction (SPE) is combined with an on-line stacking procedure (i.e. normal stacking mode, NSM). Samples could be injected up to 100 seconds, providing limits of detection (LODs) down to 74 μg/L, i.e., in the low ppb level, with relative standard deviation values (RSD, %) between 3.8% and 6.4% for peak areas for the same day, and between 6.5% and 8.1% for three different days. The usefulness of the optimized SPE-NSM-CE-MS procedure is demonstrated through the sensitive quantification of the selected pesticides in soy milk samples.

“…The degradation products presented higher toxicities than the parent compounds. Other CE methodologies using CZE [48,49,51,72,82,159] and CEC [132,133] have also been reported.…”

“…A significant number of CE-ESI-MS applications have been described for determining pesticides and herbicides [45][46][47][48][49][50][51], pharmaceuticals [52,53], heterocyclic amines [54][55][56][57], explosives [58], amines [59], carboxylic acids [60], or substituted methoxy phenols and aromatic acids [61]. However, the application of CE-ESI-MS to various environmental problems is limited by the use of nonvolatile buffer components and organic additives, such as surfactants and chiral compounds, for achieving a wide variety of separations.…”
