• (Hall P31) CHAIR: KANICKÝ

8:00 – 8:50 Recent developments in laser ablation and inductively coupled plasma mass spectrometry

• PL 3: D. GUENTHER

The major challenges of our times request sustainability in everything we are planning in the future. Environmental protection, discovery of new resources, characterization of new and lightweight materials, material replacement and reduction in the construction industry, food protection and safety and life science and medicine are important topics, among others, where analytical chemistry plays major role.

The availability of the entire portfolio of analytical techniques is of utmost improtance while constant refinement and development is required in order to provide high compatibility and flexibility for applications in aforementioned research fields.

The group for Trace Element and Micro Analysis at ETH Zurich studied a variety of instruments, processes and methods related to element analysis and isotope ratio determinations. Instruments were developed which become more and more applied. For example, a significantly improved prototype inductively coupled plasma time of flight (ICP-TOFMS) led to the renaissance of TOF-MS instruments and they are now commercially available (TOFWERK AG, Thun Switzerland). These instruments contribute to knowledge generation in many fields of research, e.g. in life science, medicine, geology and chemistry. Here we report a new sample introduction system for laser ablation generated aerosols introduced into an ICP-TOFMS, which has recently been developed and tested in our group. The aerosol washout and the improvements in terms of image acquisition time will be discussed¹.

For many decades argon has been the plasma gas of choice for ICP-MS, even though alternative gases have been proposed and tested. To exploit the possibility of argon substitution, a recently introduced nitrogen plasma source (Radom, Milwaukee, USA)² has been studied in combination with laser ablation. We also report results on direct solid analysis by LA-ICP-MS using nitrogen as plasma gas³.

Finally, the analyses of single cells gained significant attention using a cy-TOF-MS. Therefore, the geometry of the ICP-MS has been modified to improve throughput of single cells and nanomaterials⁴. The system and the current performance will be presented.

• OL 47: P. NEČAS

The aim of the study was to describe mineralogical phases related to discharge of saline mine waters and draining waters of coal heaps. Special mineralogical phases crystallize from these highly mineralized waters when entering the river system (1). By using several analytical methods in studying of mineral incrustations we are able to better understand the processes and to create a more precise geochemical model of processes (2). For this study, four samples from mine drainage and five samples from coal dumps drainage were collected. The content of the elements was measured by portable X-ray fluorescence spectrometer (pED-XRF) and for the phase composition XRD method was used. Mineralogical nature of incrustations was determined by scanning electron microscope with energy dispersive X-ray spectrometer (SEM/ED-XRF). Subsequently, representative samples with atypical mineral composition were selected for a more detailed phase analysis by micro-Raman spectroscopy which discovered local changes in the degree of luminescence. Based on previous observations, selected elements (K, Ca, V, Cr, Mn, Fe, Zn, As, Sr, Ba, Pb, Th and U) were used to create chemical distribution maps in the incrustations via laser ablation (LA-ICP-MS) and major as well as trace cations and anions were measured in sampled waters by ICP-MS. The hydrochemical type of waters was evaluated by using the Geochemist’s Workbench 12 Professional Edition with using Gtplot. All monitored water resources reach neutral to basic pH values (6.7-10.2). In the evaluated mine waters and dump drainages, the hydrochemical types of water (SO 4 – Cl⁻) with a variable content of bicarbonates and cations (Na, K, Mg, Ca) were distinguished, which noticeably contribute to the formation of incrustations at the drain or bottom of streams. Phase analysis showed us three main dominant minerals (calcite, aragonite and monohydrocalcite) which bind different elements into their structure. Based on results from laser ablation and analyses from another spectroscopic methods, we can determine correlating systems between the mobility of individual elements in water and their entrance into the incrustations.

• OL 51: J. KOPP

In recent decades, a massive expansion of nanotechnology and nanomaterials is evident, changing industry, research areas and the daily life of people. Various classes of analytical techniques have been developed to cover the requirements of nanotechnology and the characterization of nanomaterials.

Molecular vibrations are directly related to the molecular structure. The techniques of vibrational spectroscopy, including those based on either infrared absorption/reflection or Raman scattering, are well-known analytical techniques. Their microscopic/microspectroscopic counterparts developed in the second half of the 20th century are limited in spatial resolution by light diffraction. Recently this limit has been overcome by the combination of near-field optics with scanning probe microscopy (SPM). Imaging techniques described by abbreviations like AFM-IR (atomic force microscopy – infrared (imaging)) and SNIM (scanning near-field infrared microscopy) are powerful analytical techniques for nanoscience and nanotechnology (1). Nano-FTIR and TERS (tip-enhanced Raman scattering) combined the spatial and spectral information essential for both the design/development of new nanomaterials/nanosystems and a detailed description of biological systems. Nevertheless, individual experimental techniques require some specific sample preparation/treatment procedures.

The advantages and drawbacks of preparation procedures, individual imaging techniques, and spectroscopic data acquisition and processing will be demonstrated in several examples of studies (2-4) performed in our laboratory at UCT Prague.

• OL 59: M. URÍK

Since iron participates in various vital metabolic processes in the cell, it is an essential micronutrient for microorganisms. It serves as a cofactor in various microbial metabolic pathways. Thus, organisms have developed various mechanisms for its uptake and storage (1). This includes redox transformation and chelation, which also affects stability of natural ferric/ferrous precipitates (e.g., ochres). However, the determination of the exact mineral forms and speciation of iron is always challenging, especially in the case of biomass where the iron concentration is usually low (2,3). Therefore, we have collected various biogenic materials, and studied the prospects of various spectroscopic methods (e.g., Mössbauer spectroscopy (4,5)) to analyze the iron in such complex matrices (6).
