Analytical figures of merit: from univariate to multiway calibration
(American Chemical Society, 2014-07)
Figures of merit are numerical parameters that help to characterize the performance of a device or a system relative to alternative ones. In engineering, they are often defined for particular materials or machines in order ...
Recent advances in analytical figures of merit: Heteroscedasticity strikes back
(Royal Society of Chemistry, 2017-02)
With a growing number of analytical methodologies incorporating multivariate calibration models, the development of suitable estimators of their analytical figures of merit is playing an important role in modern analytical ...
Second- and higher-order data generation and calibration: A tutorial
An introduction to multi-way calibration based on second- and higher-order data generation and processing is provided, with emphasis on practical experimental aspects. After a discussion concerning a proper nomenclature ...
Practical guidelines for reporting results in single- and multi-component analytical calibration: A tutorial
Practical guidelines for reporting analytical calibration results are provided. General topics, such as the number of reported significant figures and the optimization of analytical procedures, affect all calibration ...
Excitation-emission matrices applied to the study of urban effluent discharges in the Chubut River (Patagonia, Argentina)
Natural and contaminated waters of the final reaches of the Chubut River (Patagonia, Argentina) were studied to obtain information about river organic matter and effects of domestic and industrial discharges (fishery ...
Second-order advantage obtained from standard addition first-order instrumental data and multivariate curve resolution-alternating least squares. Calculation of the feasible bands of results
In order to achieve the second-order advantage, second-order data per sample is usually required, e.g., kinetic-spectrophotometric data. In this study, instead of monitoring the time evolution of spectra (and collecting ...
