A sensitivity equation for quantitative analysis with multivariate curve resolution-alternating least-squares: Theoretical and experimental approach
(American Chemical Society, 2012-09-11)
A new equation is derived for estimating thesensitivity when the multivariate curve resolution-alternating leastsquares (MCR-ALS) method is applied to second-order multivariatecalibration data. The validity of the expression ...
Validation of models of multivariate calibration: An application in the determination of polymorphic purity of carbamazepine by near infrared spectroscopy.

Fluorescence-kinetic four-way data generation and modeling for abacavir determination in water samples
(Elsevier Science, 2020-07)
The aim of this study was to develop a fluorescence-detection based analytical methodology consisting in the photolysis of abacavir induced by UV irradiation to determine the concentration of the analyte in complex samples. ...
Vibrational cooling and thermoelectric response of nanoelectromechanical systems
(American Physical Society, 2014-09)
An important goal in nanoelectromechanics is to cool the vibrational motion, ideally to its quantum ground state. Cooling by an applied charge current is a particularly simple and hence attractive strategy to this effect. ...
Avaliação dos métodos Walkley & Black e CHN como métodos de referência para calibração multivariada na determinação de carbono orgânico em solos brasileiros
(Universidade Tecnológica Federal do ParanáCampo MouraoDepartamento Acadêmico de Química, 2015)
The modified Walkley & Black method (Embrapa method) and CHN were evaluated as reference methods to determine organic carbon in Brazilian soils using near infrared spectroscopy (NIRS) as an alternative. The main objective ...
Protein adsorption onto nanomaterials for the development of biosensors and analytical devices: A review
(Elsevier Science, 2015-05-04)
An important consideration for the development of biosensors is the adsorption of the biorecognition element to the surface of a substrate. As the first step in the immobilization process, adsorption affects most immobilization ...
Development and validation of analytical method for determining the artificial dyes in breakfast cereals by means of high performance liquid chromatography
(Instituto Adolfo Lutz, 2014)
Validation of analytical methodology is an important tool to ensure the applicability and scope of a technique for laboratory routine, establishing the limits of the quality parameters of instrumental measurements and the ...
Minimal-Invasive Analytical Method and Data Fusion: an Alternative for Determination of Cu, K, Sr, and Zn in Cocoa Beans
(2021-03-01)
In the present study, a minimal-invasive analytical method for determination of Cu, K, Sr, and Zn in cocoa beans was performed using energy X-ray fluorescence (EDXRF) and laser-induced breakdown spectroscopy (LIBS) combined ...
