A distinct approach to laser plasma spectroscopy through internal reference standard method with peak intensity-based self-absorption correction

Atomic spectrometry update – a review of advances in environmental analysis

“…Agreement for Cu and Zn was, however, poorer. The addition of copper powder and the use of Cu emission lines to correct for self-absorption effects in the determination of Ca in fennel, bay, dandelion, spinach and parsley leaves improved 183 markedly the agreement with ICP-AES data. Without correction, the LIBS results were almost four times the ICP-AES values but with correction they were within 3% of the ICP-AES results.…”
