Laser-induced breakdown spectroscopy as an analytical tool for total carbon quantification in tropical and subtropical soils: evaluation of calibration algorithms. Author(s): BABOS, D. V.; GUEDES, W. N.; FREITAS, V. S.; SILVA, F. P.; TOZO, M. L. L.; VILLAS-BOAS, P. R.; MARTIN NETO, L.; MILORI, D. M. B. P. The demand for efficient, accurate, and cost-effective methods of measuring soil carbon (C) in agriculture is growing. Traditional approaches are time consuming and expensive, highlighting the need fo... ... Repository: BDPA Publication year: 2024
Multi-Energy calibration: a practical method for determination of macro and micro nutrients in meat by ICP OES. Author(s): HIGUERA, J. M.; SILVA, A. B. S.; NOGUEIRA, A. R. de A. The multi-energy calibration (MEC) was evaluated for the determination of Ca, Cu, Fe, K, Mg, Na, P, S, and Zn in meat samples by inductively coupled plasma optical spectrometry (ICP OES). This calibra... ... Repository: BDPA Publication year: 2019
