Portable X-ray fluorescence analyzer pretended for mass
concentration defenitions in probe for alemens from
Si(14)
to U(92),
in a probe with sizes from tens parts of millimeter to
millimeters. It can be
ecology,
archeology, restoration works, paint and varnish coverings and
so on.
Probes can be liquid and firm (as
dusts, films, spray filters, and so on) The trial
sample of the device is developed by IRO.
All
the analysis
process from the data acquisition to its
processing, before accepting results as a table values
of concentration defined elements, is automated and
carried out by the built in computer.
In the portable analyzer x-ray radiation of a tube are
gathered by a polycapillary half-lens and goes on
investigated object (probe) in the form of almost parallel beam
(divergence 2 mRad). Diameter of the x-ray beam leaving a
half-lens, for the account of technology is possible to
change from the tenth shares of mm to 10 mm, commensurating it,
thus, with the real sizes of investigated object.
Built in
color CCD camera allows to observe visually, on the one hand,
investigated area, with another to combine an axis of a x-ray
beam with the centre of investigated object.
The quantitative estimation of the maintenance of elements in
analyzed probe is carried out with use of a method of
fundamental parametres, or with use of a method of pure elements.
