Analytical chemistry assisted by multi-way calibration: A contribution to green chemistry
(Elsevier Science, 2019-11-01)
A review is presented of recent multi-way calibration protocols involving three-, four- andfive-way data. A brief description of the various data structures and processing models isshown, with emphasis on model selection ...
A road map for multi-way calibration models
(Royal Society of Chemistry, 2017-08)
A large number of experimental applications of multi-way calibration are known, and a variety of chemometric models are available for the processing of multi-way data.While the main focus has been directed towards three-way ...
Simultaneous determination of ascorbic and uric acids and dopamine in human serum samples using three-way calibration with data from square wave voltammetry
(Elsevier Science, 2016-11)
We present for the first time a novel analytical method based on a model of three-way calibration using second-order data generated from the combination of records of forward (oxidation) and reverse (reduction) currents ...
N-way PLS applied to simultaneous spectrophotometric determination of acetylsalicylic acid, paracetamol and caffeine
(Pergamon-elsevier Science LtdOxfordInglaterra, 2004)
Deltamethrin determination in natural water samples via photochemically-induced fluorescence coupled to third-order multivariate calibration
(Elsevier, 2020)
In this work, an analytical method for deltamethrin determination in natural waters based on photochemicallyinduced fluorescence coupled to third-order/four-way calibration was evaluated and compared with secondorder/three-way ...
New developments for the sensitivity estimation in four-way calibration with the quadrilinear parallel factor model
(American Chemical Society, 2012-02)
Appropriate closed-form expressions are known for estimating analyte sensitivities when calibrating with one-, two-, and three-way data (vectors, matrices, and three-dimensional arrays, respectively, built with data for a ...
Recent advances in analytical calibration with multi-way data
(Royal Society of Chemistry, 2012-05)
This critical review discusses the advances which have taken place in recent years in the field of multi-way instrumental data, i.e., data that can be arranged into a mathematical object of at least three ways (when they ...
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 ...
Vector dot product used for reduced three independent variables of multivariate regression to a linear regression with one independent variable. Alcohols used like a model
(SOC CHILENA QUIMICA, 2007-09)
The aim of this work is based in the reduction of independent variables in multivariate regression analysis to one by means a vector dot product (E-3). By this way, it is omit the orthogonalized procedure to obtained valid ...
Second-order multivariate calibration with the extended bilinear model: Effect of initialization, constraints, and composition of the calibration set on the extent of rotational ambiguity
(John Wiley & Sons Ltd, 2020-03-15)
Extended bilinear modeling is popular in second-order multivariate calibration, particularly when the matrix data for each sample are of chromatographic origin. Since elution time profiles vary across samples, in both shape ...
