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.

iCAP 6000 Series ICP-OES Spectrometer Hardware Manual
Page 11 of 51 Version 1.5 – March 2006
The quartz body of the torch should be pushed into the metal torch mount. Ensure the torch
body is pushed fully into the metal torch mount. The marked line on the quartz torch is used to
locate the radial view hole correctly and should touch the metal body.

Figure 7 – Drain tubing
Cut the end of the drain tube capillary at an angle as shown.

Figure 8 – Spray chamber drain
Insert drain tube capillary until it meets the main chamber.
Figure 9 – Nebuliser to Spray Chamber Figure 10 – Nebuliser to Spray Chamber
The O-rings in the spray chamber should be inspected and replaced if any wear, or damage, is
visible. Push the Teflon insert with the attached sample tubing (supplied with the nebuliser)
into the rear of the nebuliser as far as possible without exerting undue pressure.
Using a twisting motion insert the nebuliser into the spray chamber so that the collar is a tight
fit. The collar will set the insertion depth and aid reproducibility of results.
Figure 11 – Spray chamber assembly
Attach the swan neck fitting to the Spray chamber with the fitting clamp provided. The swan
neck provided with the instrument is specially designed to prevent UV radiation from escaping
from the torch box.

Page 14 of 51 Version 1.5 – March 2006
Figure 12 – Spray Chamber fitted
Insert swan neck fitting into torch assembly holder as far as it will go, and connect
up the Nebuliser gas supply to the push-fit fitting.
Warning: It is extremely important that the correct Thermo part is used for the
swan neck. In addition, systems interlocks on the torch holder and elsewhere are there
for safety reasons and must not be bypassed. Operators could be exposed to
dangerous UV and radio frequency radiation if alternate parts are used for the swan
neck.
After assembly of the sample introduction system, a check for gas leaks at each joint should
be undertaken. This may be done by dabbing with brush dipped in a solution of detergent
in water or soap solution at each joint.
Figure 13 – Sample Capillary Tubing
Feed the sample capillary tubing from the rear of the nebuliser through the upper holder in
the cover and towards the pump.
Ensure there are no twists or bends in the nebuliser and drain PTFE tubing that may prevent
flow of the sample. Insert the sample and drain PTFE tubing into their respective Tygon pump
tubing, making sure that the drain tubing is threaded through the lower hole in the case (see
Figure 14 below) for the drain sensor to work correctly.
Please note: the drain tubing should be connected correctly to account for the counter-
clockwise flow.

iCAP 6000 Series ICP-OES Spectrometer Hardware Manual
Page 15 of 51 Version 1.5 – March 2006
Figure 14 – Sample Capillary Tubing
Pass the drain capillary tubing through the lower holder in the cover and towards the pump.
This holder contains a sensor detecting bubbles produced when the spray chamber is
draining normally. The plasma and the pump will be switched off after 2 minutes if no bubbles
are detected.
Figure 15 – Pump Tubing
Release the pump tubing clamps and locate the sample and drain pump tubing over the
pump rollers, locking the lugs on the pump tubing into the left and right clamps.
Connect the sample pump tubing to the sample capillary tubing and the drain pump tubing to
the drain capillary tubing; remember to allow for the direction of flow.
Pump tubing should be inspected before each analysis and should be replaced if there are
indications of wear.
Additional lengths of capillary tubing should be used to allow connection to the input of the
sample pump tubing to the sample and the output of the drain pump tubing to a waste
container.
Figure 16 – Pump Tension Adjustment
The pump tension can be adjusted with the plasma running and the pump stopped. Lock the
sample pump tubing and clamp into position. Release the tension adjustment and allow the
nebuliser to free aspirate. Tighten the tension adjustment until the flow just stops then tighten
by one turn. Turn on the pump and, if necessary, tighten the tension until a smooth flow is

iCAP 6000 Series ICP-OES Spectrometer Hardware Manual

produced. Do not over-tighten the pump clamps as it will result in excessive wear and tear of
the pump tubing and require replacement tubing at more frequent intervals.
6.2.2 Radial Torch Assembly

The O-rings in the metal torch mount (internally and externally) should be inspected and
replaced if any wear, or damage, is visible.

tubing to the nebuliser via the push fit connector.
Figure 24 – Nebuliser to Spray Chamber
The O-rings in the spray chamber should be inspected and replaced if any wear, or damage,
is visible.
Using a twisting motion insert the nebuliser into the spray chamber so that the spacing collar
fits against the inlet. The collar will set the insertion depth and aid reproducibility of results.

Figure 25 – Nebuliser sample tubing
Attach the sample tubing to the nebuliser using the Teflon insert.
Connect spray chamber and nebuliser assembly to the torch assembly, locked in the
instrument, using the clamp.
The torch compartment door must be closed before use.
Warning: It is extremely important that the safety interlocks are not disabled.
This could result in exposure to dangerous radio and UV frequency radiation.
After assembly of the sample introduction system, a check for gas leaks at each joint should
be undertaken. This may be done by dabbing with a brush dipped in a solution of detergent
in water or soap solution at each joint.
