Emission spectrometers using an inductively coupled plasma
(ICP) as the excitation source have various advantages over
those using a conventional excitation source, and hence have
come to be utilized more and more extensively.
The important features of the ICP are:
- Detection limit of ppb quantity level.
- No matrix effect.
- Wide measurable concentration range.
- High stability and reproducibility.
With these and many other advantages, ICP spectrometers are
widely used; their application fields include elemental analysis
for quality control, ultratrace element determination such
as for environmental water quality monitoring, and major element
determination such as for composition determination.
In order for an ICP spectrometer to get the maximum use of
the above features, it is required that:
- The spectrometer provides high resolution over a wide
- Acidic/aqueous solution samples and organic solvent solution
samples can be analyzed without addition or replacement
of the units of the instrument.
- The RF generator, spectrometer, and gas flow control unit
ensure high stability.
- Running cost is low.
- Ease and simplicity of operation are ensured through automation,
and the data system provides a wide variety of data processing
The Shimadzu ICOS-7500 is the latest, sequential, inductively
coupled plasma emission spectrometer designed to satisfy all
of these requirements.
Large database and many software programs are readily available.
