Chemometric tools improving the determination of anti-inflammatory and antiepileptic drugs in river and wastewater by solid-phase microextraction and liquid chromatography diode array detection
(Elsevier Science, 2009-07)
An analytical method for the simultaneous determination of seven non-steroidal anti-inflammatory drugs (naproxen, ketoprofen, diclofenac, piroxicam, indomethacin, sulindac and diflunisal) and the anticonvulsant carbamazepine ...
A closed-form expression for computing the sensitivity in second-order bilinear calibration
(John Wiley & Sons Ltd, 2005-11)
A general expression is derived for estimating the sensitivity of second-order bilinear calibration models, particularly parallel factor analysis (PARAFAC) and bilinear least-squares (BLLS), whether the second-order advantage ...
Chemometric resolution of fully overlapped capillary electrophoresis peaks: quantitation of carbamazepine in human serum in the presence of several interferences
(Wiley VCH Verlag, 2008-12)
Drug monitoring in serum samples was performed using second-order data generated by CE-DAD, processed with a suitable chemometric strategy. Carbamazepine could be accurately quantitated in the presence of its main metabolite ...
Modeling nonbilinear total synchronous fluorescence data matrices with a novel adapted partial least squares method
(Elsevier, 2015-01)
A new residual modeling algorithm for nonbilinear data is presented, namely unfolded partial least squares with interference modeling of non bilinear data by multivariate curve resolution by alternating least squares ...
A fast chromatographic method for determination of daidzein and genistein in spiked water river samples using multivariate curve resolution
(Sociedade Brasileira de Química, 2015-04)
This work reports the development of a fast chromatography methodology for quantitation of two phytoestrogens: daidzein (DAI) and genistein (GEN), in river water samples. The proposed method is based on High performance ...
Chemometrics-assisted multi-instrumental techniques for investigation of interactions of dapagliflozin with normal and glycated human serum albumin: application to exploiting second-order advantage for determination of glycated human serum albumin as a biomarker for controlling diabetes
(Elsevier Science, 2021-08)
In this paper, we have collected useful information about interactions of dapagliflozin (DPA) with normal human serum albumin (HSA) and glycated HSA (GHSA) by using spectroscopic and electrochemical methods. Instrumental ...
