Analytical approach for the simultaneous determination of quinolones in edible animal products. Modeling pH–modulated fluorescence excitation–emission matrices four–way arrays
(Elsevier Science, 2019-01)
This paper describes a novel procedure for the simultaneous determination of four quinolones pipemidic acid, enoxacin, marbofloxacin and enrofloxacin in different edible animal tissues. It is based on third–order data ...
Novel Augmented Parallel Factor Model for Four-Way Calibration of High-Performance Liquid Chromatography-Fluorescence Excitation-Emission Data
(Elsevier, 2015-03)
A new augmented parallel factor analysis model (Augmented PARAFAC) is presented, inspired by the useful augmentation concept employed in multivariate curve resolution-alternating least-squares (MCR-ALS), applicable to ...
Multiway analysis through direct excitation-emission matrix imaging
(Elsevier Science, 2018-11)
In this work, a direct in-flow methodology for the acquisition of excitation-emission fluorescence matrices is presented. The system is particularly suited for measurements in the order of tens of milliseconds. A light ...
A graphical user interface as a new tool for scattering correction in fluorescence data
(Elsevier Science, 2019-07)
Fluorescence spectroscopy in combination with chemometrics has proved to be a powerful tool for the study of complex systems with analytical purposes. Under ideal conditions, multidimensional fluorescence data have the ...
Excitation-emission matrix fluorescence spectroscopy combined with MCR-ALS as a tool for the forensic analysis of similar and dissimilar sets of textile fiber extracts
(Royal Society of Chemistry, 2016-12)
Trace textile fiber evidence is found at numerous crime scenes and plays an important role in linking a suspect to the respective scene. In this work, investigations into the fluorescence of fiber dyes and fibers themselves, ...
Second-order advantage with excitation-emission fluorescence spectroscopy and a flow-through optosensing device: Simultaneous determination of thiabendazole and fuberidazole in the presence of uncalibrated interferences
(Royal Society of Chemistry, 2010-04)
This paper presents a novel approach for the simultaneous determination of two widely used fungicides in a very interfering environment, combining the advantage of a spectrofluorimetric optosensor coupled to a flow-injection ...
Landscape integration of North Patagonian mountain lakes: a first approach using characterization of dissolved organic matter
(Wiley Publishing Asia, 2015-03)
North-western Patagonia contains a variety of glacially formed mountain lakes located at different positions from the treeline in the Andean Patagonian forest region. Water chemistry of six North Patagonian lakes located ...
Green analytical determination of emerging pollutants in environmental waters using excitation-emission photoinduced fluorescence data and multivariate calibration
(Elsevier, 2015-03)
An eco-friendly strategy for the simultaneous quantification of three emerging pharmaceutical contaminants is presented. The proposed analytical method, which involves photochemically induced fluorescence matrix data ...
