| Popis | Compared to other analytical techniques usually employed for elemental mapping, laser-induced breakdown spectroscopy (LIBS) offers simplicity and robustness of instrumentation, which permit on-line and in situ measurements. On the other hand, limitations due to matrix effects and calibration difficulty are well known. LIBS can be highly sensitive to these undesirable effects also because of the high density of material in the plasma. For this reason, frequently used laserablation based analytical techniques utilizes second excitation source (most often ICP) followed by optical or mass spectrometry. The simultaneous LIBS and LA-ICP-OES setups were designed by utilizing a modified and commercially available laser ablation system UP 266 MACRO (New Wave) that consists of a pulsed Nd:YAG laser operated at a wavelength of 266 nm. |
