TL;DR: In this article, a review of the most commonly used techniques for solid sample analysis is presented, relating the main instrumental advances to the expansion of the methods developed in this subject, pointing out the potential ability to overcome spectral interference and matrix effects through the development of calibration strategies to achieve the success of solid sampling in several application areas.

TL;DR: In this article, a multi-energy calibration (MEC) approach was applied for the determination of As, Ba, Cd, Cr, and Pb in fertilizer samples by microwave-induced plasma optical emission spectrometry.

TL;DR: An analytical method was developed for determination of Cd, Sn, Pd, Pt and Rh in sediments, fertilizer and sludge samples by inductively coupled plasma tandem mass spectrometry (ICP-MS/MS) as discussed by the authors.

TL;DR: The method proposed offers a simple, fast, multielemental, and robust alternative for successful determination of all five analytes in agricultural samples with low operational cost without compromising analytical performance.

TL;DR: In this article, a review of recent advances in laser-induced breakdown spectroscopy (LIBS) for minimizing matrix effects and enabling determination with satisfactory accuracy and precision is presented, and applications, advantages, and limitations of the calibration strategies, such as matrix-matching calibration, internal standardization (IS), standard addition (SA), multi-energy calibration (MEC), one point gravimetric standard addition, one-point and multi-line calibration (OP MLC), slope ratio calibration (SRC), two-point calibration transfer (TP CT), single-sample
