A Minimally Destructive

Technique for Metal Alloys

The technique was
applied to four analytical
problems: the analysis of
dried paint for trace lead;
the analysis of valuable
potteries when two
Look alike specimens
were differentiated; the
elemental analysis of ink
when lines written with
different pens could be
discriminated;
and the analysis of
electrode-plastic
interfaces. (J.Anal. At.

A new multi-element
analysis technique based
on laser- excited atomic
fluorescence was
reviewed.
Several real-world
problems, including the
analysis of paint coating
for trace lead, the
non-destructive analysis
of potteries and ink, the
chemical profiling of
electrode–plastic
interfaces, and the
analysis of ingestible lead
colloids were discussed.

We demonstrated a
minimally destructive
two-tier approach for
Multi element forensic
analysis of laser-printed
ink. The printed
document was first
screened using a
portable-X-ray
fluorescence probe. If the
results were not
conclusive, a laser
microprobe was then
deployed. (Anal.Chem.

We report an all-optical
technique for
simultaneous
multi-element analysis.
It is based on ArF laser
excited atomic
fluorescence of plumes
produced by pulsed laser
ablation.
Two spectroscopic
techniques that
compliment LIBS were
developed. One technique
is based on

photo-resonant heating of
the plasma plume; the
other technique is based
on laser-excited atomic
fluorescence of plume
species. Several
real-world problems were
addressed.
An ultra-wideband
(UWB) bandpass filter
(BPF) with notched band
and wide stopband has
been designed,
fabricated, and discussed
in this work.
