Letno poročilo 2005

aznovrstne in zelo aktualne mo`nosti uporabe
na razli~nih podro~jih, kot so npr. geologija,
metalurgija, pedologija, razvoj novih materialov,
farmacija, forenzika, arheologija, konservatorstvo
in restavratorstvo, botanika itd.
Idealna je v tistih primerih, ko so potrebne
meritve sledov elementov (< 0.1%) na povr{ini
in v materialu, ko je na voljo le majhna koli~ina
materiala (Slika 3), ali pa so vzorci dragoceni,
saj se z laserskim `arkom obseva razmeroma
majhen del povr{ine vzorca (premer 4 - 300
mm), ki zato ostane prakti~no nepo{kodovan.

IMPORTANT PURCHASE OF MAJOR RE-
SEARCH EQUIPMENT
In 2005 the Analytical Chemistry Laboratory
obtained state-of-the-art research equipment
that can be used for chemical characterization
of solid materials, namely an elemental mass
spectrometer with laser ablation unit (LA-ICP-
MS, Figure 2), which is the first hyphenated
analytical system of its kind in Slovenia. The
purchase of this system, with a value of ca.
260,000 Euro, was supported by the EU Structural
Funds and by several partners in Slovenia:
The Ministry of Higher Education, Science and
Technology, the Jo`ef Stefan Institute and the
Faculty of Chemistry and Chemical Technology
(ULJ).
LA-ICP-MS is a frontier research technique for
direct chemical (elemental) characterization of
solid materials that offers versatile and topical
measurement options in different fields such
as geology, metallurgy, pedology, material science,
farmaceutical development, forensics,
archeology, conservation and restauration,
botanics, etc. It is ideal for measurements of
trace elements (< 0.1%) at the surface and in
the bulk of a solid material, and when only a
small amount of a sample is available (Figure
3) or in situations when precious samples have
to be analysed, as the irradiation with the laser
beam affects only a very small part (diameter
of 4 - 300 mm) of the surface of a valuable
object, which is therefore left practically undamaged.
