A review on second- and third-order multivariate calibration applied to chromatographic data
(Elsevier Science, 2012-02)
Quantitative analytical works developed by processing second- and third-order chromatographic data are reviewed. The various modes in which data of complex structure can be measured are discussed, with chromatographic ...
A new modeling strategy for third-order fast high-performance liquid chromatographic data with fluorescence detection: Quantitation of fluoroquinolones in water samples
(Springer Heidelberg, 2015-02)
Matrix augmentation is regularly employed in extended multivariate curve resolution-alternating least-squares (MCR-ALS), as applied to analytical calibration based on second- and third-order data. However, this highly ...
Online Third-Order Liquid Chromatographic Data with Native and Photoinduced Fluorescence Detection for the Quantitation of Organic Pollutants in Environmental Water
(American Chemical Society, 2018-11)
Third-order liquid chromatographic data were generated online for the simultaneous quantitation of six organic environmental pollutants. The employed strategy consists in reducing the linear flow rate at the column outlet. ...
Using chemometric tools to investigate the quality of three- and four-way liquid chromatographic data obtained with two different fluorescence detectors and applied to the determination of quinolone antibiotics in animal tissues
(Elsevier Science, 2020-04)
A comparison of two multi-way methodologies is presented regarding the simultaneous quantitation of several analytes in complex samples. Both protocols are based on liquid chromatography with fluorescence detection, in the ...
Modeling four and three-way fast high-performance liquid chromatography with fluorescence detection data for quantitation of fluoroquinolones in water samples
(Elsevier Science, 2014-01)
This paper presents a study regarding the acquisition and analytical utilization of four and three-way data, acquired by following the excitation?emission fluorescence matrices at different elution times, in a fast liquid ...
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 ...
Nuevas estrategias analíticas para el análisis de muestras de composición compleja basadas en generación y modelado de datos multidimensionales
(2016-12-27)
In this work, different strategies for multidimensional data generation were evaluated, and potentialities of chemometrics algorithms were explored for the analysis of complex samples. Analytical methods were developed for ...
