“…In the SSC method, only one sample is used as the calibration standard and several emission lines of the analyte present in the standard and sample (unknown) are used. The SSC does not require a calibration curve or linear models (Yan et al 2019). respectively, in the sample used as the standard calibration.…”

“…The determination of Al and Pb was also evaluated using the singlesample calibration method -SSC, which is another recent calibration strategy for LIBS that uses only one sample as standard (reference). In this strategy, a simple correlation calculation is necessary to determine the analyte concentration in the sample with unknown concentration (Yan et al 2019).…”

“…For the use of SSC, the extent of the matrix effects between the sample and the standard should be considered the same for all elements present in the LIBS-induced plasma sample and the standard, since a direct correlation between the emission intensity and concentration of these elements will be used for the determination of the analyte. In addition, it should be considered that none of the emission lines used in the SSC (analyte emission lines and other elements used in the correlation) present spectral interferences, so that results can be obtained with satisfactory precision and recovery (Yan et al 2019).…”

“…In order to overcome these matrix effects, univariate and multivariate calibration strategies are used for LIBS: matrix-matching calibration (MMC) (Costa et al 2018b, Gomes et al 2013, Vieira et al 2018), standard addition (SA) (Yi et al 2016, one-point gravimetric standard addition (OP GSA) (Babos et al 2019), internal standardization (IS) (Aquino et al 2016, Carvalho et al 2018b, Lasheras et al 2013) calibration free (CF) (Calvacante et al 2013, Ciucci et al 1999, Tognoni et al 2010, one-point and multi-line calibration (OP MLC) (Hao et al 2018), multi-energy calibration (MEC) (Andrade et al 2019b, Babos et al 2018, Carvalho et al 2019, Castro et al 2020, Fortunato et al 2019, twopoint calibration transfer (TP CT) (Castro et al 2020), and single-sample calibration (SSC) (Yan et al 2019).…”

Matrix-matching calibration (MMC), two-point calibration transfer (TP CT), onepoint and multi-line calibration (OP MLC), single-sample calibration (SSC) and calibration free (CF) were evaluated in order to overcome matrix effects in laserinduced breakdown spectroscopy (LIBS). These calibration strategies were evaluated for direct determination of Al and Pb in waste printed circuit boards (PCB) using direct solids analysis by LIBS. Each strategy has limitations and advantages of its implementation, for the correction of matrix effects, so that it allows elementary determination with adequate accuracy. The MMC and CF proved to be excellent calibration strategies for the determination of strategic (Al) and toxic (Pb) elements by LIBS, with good recoveries (ranging from 80 to 120%) and low relative standard deviation (RSD%) values. A detailed discussion of the advantages and limitations of each of these five calibration strategies evaluated for LIBS is presented in this study. Lead concentrations in waste PCB samples are 5 to 12 times higher than established by Directive 2011/65/EU, and the samples analyzed contain between 3 and 55 g kg -1 Al, being an interesting economic and recycling source for this metal.

“…9,24 Several univariate and multivariate calibration methods have been applied to overcome these effects, including partial least squares (PLS), 9,25 artificial neural networks (ANN), 9,25 principal component regression (PCR), 9,25 external calibration (EC), 18,24 internal standardization (IS), 24 calibration-free (CF), 26,27 one-point calibration (OPC), 27,28 CF inverse, 27,29 C-sigma, 27,30 and single-sample calibration (SSC). 31 In particular, the SSC method does not require the calculation of plasma temperature, electron number density or other experimental parameters. [26][27][28][29][30] The use of a single standard to produce several signal intensities (multi-points), which avoids the preparation of a set of solid standards with a similar matrix to test the samples at different analyte concentrations, is very attractive.…”

Spark discharge (SD) laser-induced breakdown spectroscopy (LIBS) is a technique suitable to overcome the low energies of lasers by reheating the plasma, increasing the emission intensities and to perform single-standard calibration. A calibration method called one-point and multi-voltage calibration (OP-MVC), which requires two different voltages applied to both the standard and the sample, is proposed for use with SD-LIBS. The performance of this method was compared to that of the onepoint and multi-lines calibration (OP-MLC) and the slope ratio calibration (SRC) methods for LIBS determination of Al in certified reference plant leaves and P in commercial fertilizers. No statistical differences at the 95% confidence level were observed between the Al and P concentrations determined by OP-MVC LIBS for the Al certified values and the P values measured by high-resolution continuum-source flame atomic absorption spectrometry (HR-CS FAAS). The limit of detection (LOD) for P was 0.60 wt% P2O5 and 35.1 mg kg -1 for Al. The relative standard deviation (n=3) was typically 7% for Al and in the 4 -10% range for P.

Laser‐induced breakdown spectroscopy (LIBS) is a method of atomic emission spectroscopy (AES) based on a laser‐generated plasma. Powerful laser pulses are focused on a sample to atomize a small mass of material resulting in the formation of a microplasma containing free atoms electronically excited to emit light. The plasma light is spectrally resolved and detected to determine the elemental sample composition based on the unique emission spectrum of each element. Because of the simplicity of the method, it is suited for analyses that cannot be carried out using conventional techniques of AES such as measurements that must be conducted outside of an analytical laboratory. A particular advantage of LIBS is the ability to analyze gases, liquids, and solids in situ, directly, with little or no sample preparation allowing rapid measurement capability. Although LIBS offers sensitive detection for many elements, it is not an ultrasensitive detection technique and, under field conditions, the method does not typically provide the high accuracy and precision offered by laboratory‐based AES methods. Although basically an element detection method, complex targets (e.g. explosives, pathogens, and chemical agents) can be identified through analysis of the LIBS spectrum using advanced mathematical methods (e.g. multivariate analysis, neural networks).
