Laboratorij za analizno kemijo
Analytical Chemistry Laboratory
van Elterena opravljal raziskovalno delo za
doktorsko disertacijo
- Doc. dr. Ivan [vancara iz Univerze v Pardubicah,
^e{ka, je bil v L04 na eno - tedenskem
delovnem obisku v okviru bilateralnega
projekta
- Prof. Axel Berner iz In{tituta za eksperimentalno
fiziko, Univerza na Dunaju,
Avstrija, je bil na ve~ kraj{ih delovnih obiskih
v zvezi z razvojem posebnega sistema za
vzor~evanje zra~nih delcev na izvoru
POMEMBNA NABAVA VELIKE
RAZISKOVALNE OPREME
V Laboratoriju za analizno kemijo smo v letu
2005 nabavili moderno raziskovalno opremo
namenjeno kemijski karakterizaciji trdnih
materialov “Elementni masni spektrometer z
lasersko ablacijo” (LA-ICP-MS, Slika 2), ki je prvi
tovrstni sklopljeni analizni sistem v Sloveniji.
Nakup opreme v vrednosti 61 mio SIT so podprli
strukturni skladi EU in slovenski partnerji:
Ministrstvo za visoko {olstvo, znanost in
tehnologijo, Univerza v Ljubljani ter Institut
Jo`ef Stefan.
LA-ICP-MS predstavlja najsodobnej{o raziskovalno
tehniko za direktno kemijsko (elementno)
karakterizacijo trdnih materialov, ki nudi

(mikrosonda`i) z lasersko ablacijo z vidnimi kraterji,
ki jih je izdolbel laserski `arek, ~emur je sledila
dolo~itev elementov z ICP-MS. Primer za idealno
uporabo LA-ICP-MS, ko je na voljo le izredno majhna
koli~ina materiala.

of Analytical Chemistry, University
of Pardubice, Pardubice, Czech Republic
Visits from abroad:
- Dr. Emily A. Hutton, Dublin City University,
Ireland has accomplished a one - year
postdoctoral research visit to our Laboratory,
working in the area of electrochemical sensors
and microsensors
- Mr. Michael Beeston from the University of
Exeter, United Kingdom has been on a several
months work visit under the supervision
of his co-mentor J. T. van Elteren from our
Laboratory, to perform a part of his PhD research
program
- Asst. Prof. Ivan [vancara from the University
of Pardubice, Czech Republic has been on a
one - week work visit in the framework of a
bilateral project
- Prof. Axel Berner from the Institute of Experimental
Physics, University of Vienna, Austria
has been on several short - term working visits
in connection with the development of a
special system for the size-segregated sampling
of aerosols at the source of emission

LA-ICP-MS analysis (microprobing), displaying craters
left behind by drilling with the laser beam. This
example illustrates that LA-ICP-MS is an ideal technique
for elemental microanalysis of very small samples.
