Multi-element analysis of aqueous solutions
in compliance with the German Drinking
Water regulation and the German Water
Discharge Law is one of the main application
areas of the ICPE-9000 (Inductively CoupledPlasma Emission spectrometer). The
performance data and system characteristics
of this instrument are tailored specifically to
the requirements of water analysis. Keywords
such as sample throughput, operating costs
and performance outline user expectations in
this application segment.
■ High sample throughput
The ICPE-9000 is suitable for axial and radial
plasma observation. Its high-performance
Echelle optics enable the effective use of the
entire 1024 x 1024 pixel CCD detector area.
In this way, a resolution of better than
0.005nm is attained. The extremely sensitive
detector with antiblooming function reliably
acquires signal intensities, even at long
exposure times. All samples can therefore be
determined accurately within one single
analysis sequence – even those samples with
very different element concentrations. The
unique “reprocessing” function of the
ICPEsolution software enables the
determination of additional elements or
changing the concentration range for
alternate wavelengths without the need for
new measurements. Time-consuming dilution
of samples is finally a thing of the past.

■ Low argon consumption
The vacuum optics combined with mini torch
technology considerably reduces the argon
gas consumption, which usually constitutes a
major part of the operating costs. The
innovative mini torch actually reduces the
argon gas consumption by half that of
conventional torches and allows a plasma
gas flow of only 10L/min without loss in
sensitivity. In addition, time-consuming
purging of the optics with ultra-pure gas is no
longer necessary. The system is ready for
operation and stable within the shortest
possible time. Equipped with the optional
autosampler ASC-6100, the ICPE-9000 can
be fully automated for high sample
throughput operation. The system status
including information about temperature,
vacuum and gas settings is monitored
continuously and can be retrieved at any
time.

■ Analysis of natural water
An extensive program of accessories is
available for sample introduction. Aqueous
samples, for example drinking water, are
introduced into the cyclone spray chamber
via a coaxial nebulizer and transferred
subsequently into the mini torch via the
carrier gas flow of 0.7 mL/min. The system
parameters are shown in Table 1.
Under these conditions, a series of more than
20 drinking water and mineral water samples
has been analyzed for main and trace
elements. A reference material (NIST SRM
1640) was measured along with the series as
a control sample. The excellent recoveriesare shown in Table 2.
