1 Introduction to the iCAP

1.1 Overview

7000 Series
The iCAP 7000 Series is a range of Inductively Coupled Argon 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.
Most samples are liquids that are pumped through a nebuliser 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 that become excited and emit characteristic light which is
measured and corresponds to the concentration of each element type in
the original sample.
Control of the spectrometer is provided by PC-based Thermo
Scientific™ Qtegra™ Intelligent Scientific Data Solution™ (ISDS).
To avoid loss of analytical performance and compromising safety only
Thermo Scientific specified parts should be used.
The iCAP 7000 spectrometer consists of several major components:
plasma torch and sample introduction parts
radio frequency power generator
optical system
CID detector with thermoelectric cooling
Control electronics
Warning: Before operating your iCAP ensure you read and understand
all the safety information at the end of this document. ▲
To comply with safety and warranty requirements, the iCAP 7000,
accessories and associated equipment must be installed by a Thermo
Scientific-trained and certified engineer.
Specific site requirements are required for the iCAP 7000 series ICP-
OES. Please see the Working Area Requirements section below for
details.
