Typographical Conventions
This section describes typographical conventions that have been
established for Thermo Fisher Scientific manuals.
Signal Words
Make sure that you follow the precautionary statements presented in
this manual. The special notices appear different from the main flow of
text:
Viewpoint Orientation
The expressions left and right used in this manual always refer to the
viewpoint of a person that is facing the front side of the instrument.
Data Input
Throughout this manual, the following conventions indicate data input
and output via the computer:
•Messages displayed on the screen are represented by capitalizing the
initial letter of each word and by italicizing each word.
•Input that you enter by keyboard is identified by quotation marks:
single quotes for single characters, double quotes for strings.
•For brevity, expressions such as “choose File > Directories” are used
rather than “pull down the File menu and choose Directories.”
•Any command enclosed in angle brackets < > represents a single
keystroke. For example, “press <F1>” means press the key labeled
F1.
•Any command that requires pressing two or more keys
simultaneously is shown with a plus sign connecting the keys. For
example, “press <Shift> +<F1>” means press and hold the <Shift>
key and then press the <F1> key.
•Any button that you click on the screen is represented in bold face
letters. For example, “click Close”.
NOTICE
Points out possible material damage and other important information
in connection with the instrument.
Tip Highlights helpful information that can make a task easier.

Functional Description
Introduction
3-2 iCAP 7000 Plus Series ICP-OES Operating Manual (P/N BRE0004150, Revision C) Thermo Scientific
Introduction
The Thermo Scientific iCAP 7000 Plus Series ICP-OES is a range of
inductively coupled plasma-optical emission spectrometers (ICP-OES),
which use an echelle optical design and a Charge Injection Device
(CID) solid-state detector to measure trace elemental concentrations in
a wide range of samples.
Typical samples that are analyzed by ICP-OES are liquids. They are
pumped through a nebulizer to produce a fine spray. The large droplets
are removed by a spray chamber and the small droplets then pass
through to the plasma.
The solvent is evaporated and the residual sample decomposes to atoms
and ions. These are excited by the electrical Radio Frequency (RF)
generated plasma, which is at a temperature of approximately 9000 K.
When they decay to a lower energy state, they emit a set of wavelengths
of light that is unique for each element. The intensity of this light is
measured and corresponds to the concentration of the element in the
original sample.
The iCAP 7000 Plus Series ICP-OES consists of several major
components:
•Plasma torch and sample introduction parts
•Radio frequency power generator
•Echelle polychromator optical system
