Safety Practices and Hazards
Hazard Warnings
In addition to the hazard warnings specified in your spectrometer
operation manual, specific hazard warnings have been included in
this operation manual. These warnings state the hazard, describe
how to avoid it and specify the possible consequences of not
following the instructions. Read all warnings carefully and observe
them at all times.
Electrical Hazards
The SIPS electronic control module contains electrical circuits,
devices and components operating at dangerous voltages. Contact
with these circuits, devices and components can cause death, serious
injury or painful electric shock. Panels or covers retained by screws
on the SIPS may be opened only by an Agilent field service engineer.
A blown fuse should be replaced only with one of the size and rating
specified in the text adjacent to the fuse holder. Always ensure that
the accessory is turned off and disconnected from the mains supply
before attempting any replacement.
Moving Parts Hazard
During normal operation of the SIPS accessory, there are rotating
and automatic clamping components. To avoid injury or damage
ensure that all fingers, clothing etc. are kept well clear of these parts
during operation.
Chemical Hazards
The SIPS accessory may involve the use of materials that are
corrosive or otherwise hazardous. Careless, improper or unskilled
use of these materials can cause serious personal injury or an
environmental hazard.
Always ensure that laboratory safety practices governing the use,
handling and disposal of hazardous materials are strictly observed.
These safety practices should include wearing the appropriate safety
clothing.
10 Agilent Sample Introduction Pump System SIPS 10/20 User’s Guide
Safety Practices and Hazards
Always ensure that the sample introduction system is thoroughly
flushed with distilled water and that the contents of the drain or
waste container are known and disposed of if necessary before
touching any part.
Other Precautions
The pump module of the SIPS accessory weighs approximately 5.5 kg
(12 lb). To avoid injury or damage to the pump module, take care
when lifting or moving the accessory so as not to drop it.
The use of the SIPS in any manner other than that specified by
Agilent may impair the protection provided by the product.

Safety Practices and Hazards
CE Compliance
Your SIPS has been designed to comply with the requirements of the
Electro-magnetic Compatibility (EMC) Directive and the Low Voltage
(electrical safety) Directive (commonly referred to as the LVD) of the
European Union. Agilent has confirmed that each product complies
with the relevant Directives by testing a prototype against the
prescribed EN (European Norm) standards.
Proof that a product complies with the Directives is indicated by:
The CE Marking appearing on the rear of the product.
The documentation package that accompanies the product,
containing a copy of the Declaration of Conformity. This
Declaration is the legal declaration by Agilent that the product
complies with the Directives, and also shows the EN standards to
which the product was tested, to demonstrate compliance.
Electromagnetic compatibility
EN55011/CISPR11
Group 1 ISM equipment: group 1 contains all ISM equipment in
which there is intentionally generated and/or used conductively
coupled radio- frequency energy which is necessary for the internal
functioning of the equipment itself.
Class A equipment is equipment suitable for use in all
establishments other than domestic and those directly connected to a
low voltage power supply network which supplies buildings used for
domestic purposes.
This device complies with the requirements of CISPR11, Group 1,
Class A as radiation professional equipment. Therefore, there may be
potential difficulties in ensuring electromagnetic compatibility in
other environments, due to conducted as well as radiated
disturbances.

Introduction
2. Introduction
About this Manual 19
The Sample Introduction Pump System (SIPS) is an integrated,
efficient dilution system for flame AA and is suitable for use with
most Agilent (flame) atomic absorption spectrometers.
In some instruments the control module is built in to the instrument
(e.g., the Agilent 280FS AA). For these instruments, installation
instructions for the control module can be ignored. It is still
necessary to unpack and install the SIPS pump module.
The unique range of capabilities and applications provided by the
SIPS includes:
Online 10 point calibration from a single standard
Online standard additions calibration from a single standard
Intelligent online dilution of overrange samples with ‘Smart
Rinse' to reduce memory effects
Online preparation of analytical spikes, using a single standard
Online addition of chemical modifiers such as ionization
suppressants, releasing agents or internal standards
An extended dynamic range for flame AA, approaching that of
ICP-OES
The SIPS accessory is available as a single pump (SIPS 10) or dual
pump system (SIPS 20). The SIPS 10 provides online calibration and
sample dilution, while the SIPS 20 provides the added capabilities
possible with dual pump operations, including online standard
additions calibration, spiking of samples and addition of modifiers.

Introduction
CAUTION
The SIPS is not suitable for use with organic solvents because the tubing is not
resistant to these solvents.
to nebulizer

diluent
sample
Figure 1 The SIPS 10 single pump unit
The SIPS 10 uses a single pump to combine the sample (or a bulk
standard) with a small flow of diluent. Reducing the pump speed
results in a reduced flow of sample. With the nebulizer uptake rate
constant, the diluent flow is increased, effectively diluting the
sample. Using accurate computer control of the pump speed, online
dilution and automatic calibration are possible.

diluent
Figure 2 The SIPS 20 dual pump system
The SIPS 20 uses two pumps to deliver sample and a standard or
modifier to the nebulizer. Controlling the relative speeds of both
pumps in the SIPS 20 allows the amount of standard or modifier
added to the sample to be precisely regulated, facilitating online
standard additions calibration, spiking of samples and addition of
modifiers. Samples can still be diluted online by reducing the sample
pump speed relative to the speed of the second pump.
SIPS supports both manual and automatic sampling with the Agilent
flame autosamplers. The diluter option for the Agilent SPS 3
autosampler is not required and cannot be used in conjunction with
SIPS, since the SIPS automatically provides all dilution operations.
About this Manual
This manual includes instructions for installing, using and
maintaining the SIPS. It is intended for use by laboratory personnel
responsible for the day-to-day use of an Agilent AA instrument fitted
with a SIPS unit.
