Applications of electrochemical data analysis by multivariate curve resolution-alternating least squares
(Elsevier, 2017-03)
Electrochemistry studies the relationship between electricity and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice-versa. Chemometrics is the chemical ...
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 ...
Detection Of Malathion In Food Peels By Surface-enhanced Raman Imaging Spectroscopy And Multivariate Curve Resolution
(ELSEVIER SCIENCE BVAMSTERDAM, 2015)
Exploring in vivo violacein biosynthesis by application of multivariate curve resolution on fused UV-VIS absorption, fluorescence, and liquid chromatography-mass spectrometry data
(Springer HeidelbergHeidelbergAlemanha, 2013)
Colloidal gold clusters formation and chemometrics for direct SERS determination of bioanalytes in complex media
(2020-01-05)
In this work, we report the sensitive and selective sensing of the purine bases adenine and guanine in urine matrix by using surface-enhanced Raman spectroscopy (SERS) and a colloidal SERS substrate. To identify suitable ...
The effect of data matrix augmentation and constraints in extended multivariate curve resolution–alternating least squares
(John Wiley & Sons Ltd, 2017-03)
The reliability of results obtained by multivariate curve resolution (MCR) methods is strongly dependent on the absence or presence of a small degree of rotational ambiguity associated to them. In this work, the effect of ...
Dispersive liquid–liquid microextraction of quinolones in porcine blood: Validation of a CE method using univariate calibration or multivariate curve resolution-alternating least squares for overlapped peaks
(Wiley VCH Verlag, 2017-04)
In the previously published part of this study, we detailed a novel strategy based on dispersive liquid–liquid microextraction to extract and preconcentrate nine fluoroquinolones in porcine blood. Moreover, we presented ...
Resolution of intermediate surface species by combining modulated infrared spectroscopy and chemometrics
(Elsevier Science, 2019-02)
In this work, aiming at exploiting the essential particularities of modulation excitation spectroscopy (MES) coupled to phase sensitive detection (PSD) and chemometrics, a data analysis procedure was implemented to analyze ...
