A simple multidimensional system for direct injection of large volumes has been developed for the determination of three naphthalene-derivative pesticides [2-(1-naphthyl) acetamide (NAD), 1-naphthyl methylcarbamate (carbaryl) and 1-naphthol] in water using fluorescence detection. The capability of restricted-access medium (RAM), pre-columns for eliminating large interfering molecules, combined with...
Four polysaccharide-based chiral stationary phases have been used to separate the enantiomers of fourteen O,O-dialkyl-1-benzyloxycarbonyl-aminoarylmethyl phosphonates. These polysaccharide-based chiral stationary phases are Chiralpak AD, Chiralpak AS, Chiralcel OG and Chiralcel OJ. The data obtained indicate that the chiral separation ability for these organophosphonate compounds are in the order...
