Two Q-switched Nd:YAG lasers (UP-266 MACRO-New Wave and Quantel Brilliant) operated at fourth harmonic frequency (266 nm) and at the fundamental wavelength of 1064 nm, respectively, were used in our double pulse experiments. The laser-induced plasma radiation was transported by a fiber optic system onto the entrance slit of a monochromator (Jobin Yvon TRIAX 320) with ICCD detector (Jobin Yvon Horiba). LA-ICP-MS technique is based on the transport of the dry aerosol formed during laser ablation to next excitation/ionization source (ICP). Recently LA-ICP-MS has increasingly been used to quantify trace elements with a high spatial lateral resolution and low limits of detection in many different materials, including industrial materials, geological samples and human remains. A UP 213 New Wave laser ablation device coupled to a Model 7500ce Agilent ICP-MS instrument was employed to examine feasibility of measurement and quantification of spatial distribution of elements in biominerals (bones, teeth and kidney stones).

Pro LIBS experimenty v double pulse uspořádání byly použity dva Nd:YAG lasery (UP-266 MACRO – New Wave a Quantel Brilliant) pracující na čtvrté harmonické frekvenci 266 nm a fundamentální vlnové délce 1064 nm. Záření laserem buzeného mikroplazmatu bylo transportováno pomocí vláknové optiky na vstupní štěrbinu monochromátoru Jobin-Yvon TRIAX s ICCD detektorem Jobin-Yvon Horiba. LA-ICP-MS instrumentace se sestávala z laserového ablačního systému UP-213 New Wave a ICP-MS spektrometru Agilent – Model 7500ce. Tyto systémy byly použity pro srovnávací experimenty stanovení prvkové distribuce v biominerálech jako jsou kosti, zuby a močové kameny.
