The LEA-S500 laser analyzer is considered as regards the main advantages in use for analysis of elemental
composition of a wide range of substances and materials. Methods are described for the quantitative analysis
of titanium-based alloys, rutile concentrates, and quartz sands. A comparison is made of the methods used in
measurements with the LEA-S500 and those in wet chemistry, x-ray fluorescence, and atomic absorption.
Keywords: chemical analysis, multielement analysis, laser atomic-emission spectrometer, laser-spark emis-
sion spectrometry, measurement methods, analytical chemistry, titanium alloys, rutile concentrates, quartz
The latest development methods have been combined
with recent designs in the LEA-S500 analyzer, which means
that the instrument can be used in technological, input, and
shipping monitoring of product quality, and it also substan-
tially extends the sphere of use for analyzing chemical com-
positions of various substances and materials.
During 2008, the authors of the present paper developed
new methods of performing measurements on refractories
[1 – 3], titanium-base alloys, cast iron, ferrous alloys, zircon
and rutile concentrates, quartz sands, ground sandstones,
quartzites, and vein quartz, glass (building, medical, and
container types ), especial-purity copper, rare-earth ele
ment crystals, and methods of determining impurity distribu
tions in semiconductor materials and evaluating the reliabil
ity of analyses by wet chemistry. The determination range for
concentrations of compounds and elements is from ppm to
Simultaneously, in the Czech Republic (University of
Pardubice and Liberec Technical University) methods were
developed for determining chromium in factory specimens
of wool dyed with dyes of various colors and containing
chromium compounds with various valencies. The limit of
detection for chromium in this method was 4 – 10 mg/kg.
There also the MATEX PM laboratory introduced automated
monitoring of converter and furnace slags.
We consider the main advantages of the LEA-S500 over
alternative analytical instruments.
In the chemical analysis of solid monolithic materials
(metals, alloys, glasses, ceramics, and so on), the sample
preparation involves producing a flat part of the surface, and
for a glass the analysis zone is additionally ground . It is
possible to analyze wires, spheres, and cylindrical, convex,
and concave components by means of adaptors (included in
the kit) without additional treatment.
In the case of powder samples (components of refracto
ries, slags, concentrates, sands, and so on) the materials are
ground up and subsequently pressed into tablets by the use of
PVA glue. The sample preparation for refractories, powders,
slags, and similar materials takes 10 – 30 min and does not
require any change in the state of aggregation of the samples
or the use of expensive consumable materials and especial-
