  Laser Induced Breakdown Spectroscopy is a fast and contactless method for a spectrochemical material analysis. The mobile remote modification of the basic setup is unique device with the ability to determine elemental composition of the sample in situ. Laboratory of laser spectroscopy is engaged in the development and applications of methods LIBS for more then 15 years. In the last few years the attention is also aimed to the development of the mobile device for the Stand-Off variation of the LIBS technique. The actual state of development is discussed togehther with the description of the optical design, construction, instrumentations included and measurement test for the distance of 6 m. Actual and following development stages are also mentioned.

  Application of laser-induced breakdown spectroscopy to the analysis of algal biomass for industrial biotechnology
  journal article in Web of Science
  We report on the application of laser-induced breakdown spectroscopy (LIBS) to the determination of elements distinctive in terms of their biological significance (such as potassium, magnesium, calcium, and sodium) and to the monitoring of accumulation of potentially toxic heavy metal ions in living microorganisms (algae), in order to trace e.g. the influence of environmental exposure and other cultivation and biological factors having an impact on them. Algae cells were suspended in liquid media or presented in a form of adherent cell mass on a surface (biofilm) and, consequently, characterized using their spectra. In our feasibility study we used three different experimental arrangements employing double-pulse LIBS technique in order to improve on analytical selectivity and sensitivity for potential industrial biotechnology applications, e.g. for monitoring of mass production of commercial biofuels, utilization in the food industry and control of the removal of heavy metal ions from industrial waste waters.

  The development of a remote laser-induced breakdown spectroscopy (LIBS) setup with an off-axis Newtonian collection optics, Galilean-based focusing telescope, and a 532nm flattop laser beam source is presented. The device was tested at a 6m distance on a slice of bone to simulate its possible use in the field, e.g., during archaeological excavations. It is shown that this setup is sufficiently sensitive to both major (P, Mg) and minor elements (Na, Zn, Sr). The measured quantities of Mg, Zn, and Sr correspond to the values obtained by reference laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) measurements within an approximately 20% range of uncertainty. A single point calibration was performed by use of a bone meal standard . The radial element distribution is almost invariable by use of LA-ICP-MS, whereas the LIBS measurement showed a strong dependence on the sample porosity. Based on these results, this remote LIBS setup with a relatively large (350mm) collecting mirror is capable of semiquantitative analysis at the level of units of mg kg-1.

  Laser-ablation based spectrochemical analytical methods could be used in applications in which the capability for spatially resolved analysis is required. Such analysis gives a 2-D or 3-D map of the monitored chemical elements. Here we introduce automation of a 2-D surface analysis in the laser-induced breakdown spectroscopy setup by implementation of an autofocus algorithm based on the evaluation of the image sharpness. The most suitable algorithm with respect to its speed, accuracy, and durability against digital noise is chosen by testing different gradient-based methods and methods working in the frequency domain.

  The capability of Laser-Induced Breakdown Spectroscopy for elemental mapping of plant tissues is discussed in wider context. Comparison with another laser-ablation based method (LA-ICP-MS) and with synchrotron hard-X-ray radiation microradiography and micro-CT techniques is provided.
