Calibration strategies applied to laser-induced breakdown spectroscopy: A critical review of advances and challenges
(2020-01-01)
Over the years, laser-induced breakdown spectroscopy (LIBS) has been reported in the literature as an alternative to traditional methods of analysis, becoming well established among spectroanalytical techniques. LIBS is a ...
Calibration strategies for elemental determination using direct solid analysis by x-ray spectroscopy and laser-induced breakdown spectroscopy
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2020-07-30)
Direct analysis of solid samples using techniques such as wavelength dispersive X-ray fluorescence (WD XRF), X-ray absorption near-edge structure (XANES) spectroscopy and laser-induced breakdown spectroscopy (LIBS); have ...
Simultaneous quantification of seven multi-class organic molecules by single-shot dilution differential pulse voltammetric calibration
(2022-01-15)
The contamination of water sources by anthropogenic activities is a topic of growing interest in the scientific community. Therefore, robust analytical techniques for the determination and quantification of multiple ...
The Gaia-ESO Survey: Calibration strategy
(2017)
The Gaia-ESO survey (GES) is now in its fifth and last year of observations and has produced tens of thousands of high-quality spectra of stars in all Milky Way components. This paper presents the strategy behind the ...
An integrated approach to the simultaneous selection of variables, mathematical pre-processing and calibration samples in partial least-squares multivariate calibration
(Elsevier Science, 2013-07)
A new optimization strategy for multivariate partial-least-squares (PLS) regression analysis is described. It was achieved by integrating three efficient strategies to improve PLS calibration models: (1) variable selection ...
On-the-fly calibrating strategies for evolutionary algorithms

Multi-energy calibration applied to atomic spectrometry
(2017-08-22)
Multi-energy calibration (MEC) is a novel strategy that explores the capacity of several analytes of generating analytical signals at many different wavelengths (transition energies). Contrasting with traditional methods, ...
