5 Introduction to the iCAP 6000
5.1 Overview
The iCAP 6000 Spectrometer 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 provide elemental analysis.
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. The residual sample decomposed to atoms and ions
that become excited and emit characteristic light which is measured, giving a measurement of
the concentration of each element type in the original sample.
Control of the spectrometer is provided by PC based iTEVA software.
To avoid loss of analytical performance and compromising safety only Thermo Electron
specified parts should be used.
5.2 System Configuration
iCAP 6300radial – standard gas box and radial plasma view optics
iCAP 6500radial – full mass flow control gas box, radial optics and enhanced software
iCAP 6300duo – standard gas box, axial and radial plasma view optics
iCAP 6500duo – full mass flow control gas box, axial, radial optics and enhanced software
The iCAP 6000 spectrometer consists of several major components:
an optical system; a radio frequency power generator; a CID detector with thermoelectric
cooling; interlocks; a plasma torch and sample introduction parts.
6 Spectrometer Installation
To comply with safety and warranty requirements the iCAP 6000, accessories and associated
equipment must be installed by a Thermo Electron trained and certified engineer.
6.1 Pre-installation Manual
Specific site requirements are required for the iCAP 6000. Please see the separate Pre-
Installation Manual section.
6.2 Standard Sample Introduction Glassware Assembly
Warning: Appropriate care and safety procedures should be followed to avoid
breaking any glassware and causing injury to the operator. Broken glassware
should be handled with appropriate care.
6.2.1 Dual Torch Assembly
Figure 1 Dual Torch Assembly – Metal Torch Mount
The O-rings in the metal torch mount (internally and externally) should be inspected and
replaced if any wear, or damage, is visible.
