2. Introduction
About this Manual 20
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

Introduction
18 Agilent Sample Introduction Pump System SIPS 10/20 User’s Guide
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.
CAUTION
The SIPS is not suitable for use with organic solvents because the tubing is not
resistant to these solvents.
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.

Introduction
Agilent Sample Introduction Pump System SIPS 10/20 User’s Guide 19
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.
