Third order chromatographic-excitation–emission fluorescence data: Advances, challenges and prospects in analytical applications
(Elsevier, 2017-08)
Three analytical methodologies for the generation of third-order liquid chromatography–excitation–emission fluorescence matrix (LC–EEM) data are presented. Instrumental requirements were evaluated considering equipment ...
Contribution to second-order calibration based on multivariate curve resolution with and without previous chromatographic synchronization
(Elsevier Science, 2019-10-31)
Rotational ambiguity in the bilinear solutions provided by multivariate curve resolution - alternating least-squares (MCR-ALS) leads to an additional source of uncertainty in the estimation of analyte concentrations by ...
Three-way calibration using PARAFAC and MCR-ALS with previous synchronization of second-order chromatographic data through a new functional alignment of pure vectors for the quantification in the presence of retention time shifts in peak position and shape
(Elsevier Science, 2021-02-15)
In the present contribution is shown the application of the recently developed functional alignment of pure vectors (FAPV) as a proper algorithm to align second-order chromatographic data with severe retention time shifts ...
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 ...
The effect of constraints on the analytical figures of merit achieved by extended multivariate curve resolution-alternating least-squares
(Elsevier Science, 2018-03)
Multivariate curve resolution-alternating least-squares (MCR-ALS) is the model of choice when dealing with some non-trilinear arrays, specifically when the data are of chromatographic origin. To drive the iterative procedure ...
