Laser-induced breakdown spectroscopy; LIBS; LA-ICP-MS; elemental mapping;
Laser induced breakdown spectroscopy (LIBS) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) have been applied for high-resolution mapping of accumulation and distribution of heavy metal (lead) and nutrition elements (potassium, manganese) in leaves of Capsicum annuum L. samples. Lead was added in a form of Pb(NO3)2 at concentration up to 10 mmol L−1 into the vessels that contained tap water and where the 2-months old Capsicum annuum L. plants were grown another seven days. Two dimensional maps of the elements are presented for both laser-assisted Analytical Methods. Elemental mapping performed on fresh (frozen) and dried Capsicum annuum L. leaves are compared.
