Ionic liquids for improving the extraction of NSAIDs in water samples using dispersive liquid-liquid microextraction by high performance liquid chromatography-diode array-fluorescence detection
(Elsevier B.V., 2015)
A rapid, sensitive and efficient analytical method based on the use of ionic liquids for determination of non-steroidal anti-inflammatory drugs (NSAIDs) in water samples was developed. High-performance liquid chromatography ...
Poly(methyltetradecylsiloxane) immobilized onto silica for extraction of multiclass pesticides from surface waters
(Elsevier Science BvAmsterdamHolanda, 2007)
Science based calibration for the extraction of 'analyte-specific' HPLC-DAD chromatograms in environmental analysis
(Elsevier Science, 2011-01)
Multivariate science based calibration (SBC) has been applied to the resolution of overlapped peaks in liquid chromatography with diode array detection (LC-DAD). Complex river water samples spiked with 11 pharmaceutical ...
Development and validation of a High Performance Liquid Chromatography-Diode Array Detection method for the determination of aging markers in tequila
(2008)
A solid-phase extraction procedure followed by analysis by high performance liquid chromatography (HPLC) with UV-vis photodiode array detection (DAD) is proposed to simultaneously determine 11 aging markers in tequila. The ...
Discriminant analysis of Annona muricata and Rollinia mucosa extracts by multivariate curve resolution and partial least-squares regression of liquid chromatography-diode array data
(Sociedade Brasileira de Química, 2015-12)
Species of the Annonaceae family are used in traditional medicine, and several antitumor acetogenins have been isolated from the leaves of Annona muricata and Rollinia mucosa. Leaves samples (self-shaded and sun-exposed) ...
Fast chromatographic method for the determination of dyes in beverages by using high performance liquid chromatography-Diode array detection data and second order algorithms
(Elsevier Science, 2009-09)
A fast chromatographic methodology is presented for the analysis of three synthetic dyes in non-alcoholic beverages: amaranth (E123), sunset yellow FCF (E110) and tartrazine (E102). Seven soft drinks (purchased from a local ...
