Reproductibility of Low Elemental Concentrations
Experimental studies have demonstrated that the Milli-Q Element system not only
provides ultrapure water, with extremely low levels of elemental concentrations, but
also reliably and consistently delivers the same high water quality on a continuous
basis. The analytical scientist can consider the ultrapure water quality from a Milli-Q
Element system as an experimental constant.
The data below (Graphs 1-3) shows the results from an experiment comparing the
quality of Milli-Q Element product water from the same system delivered either via a
hands-free dispenser under a laminar flow hood (using foot-pedal operation), with a
0,1 µm Optimizer® filter or via a hand-held point-of-use dispenser with a 0,22 µm
Millipak® end filter. These results demonstrate that the hands-free point-of-use dispenser
designed specifically for the Milli-Q Element system, which allows the product water
to be delivered under a laminar flow hood, improves the quality and reproducibility
of the ultrapure water produced.

These low detection levels allow new
applications, such as elemental
fingerprinting, to be employed in such
diverse fields as forensic science, the food
and beverage industry and astrogeology.
With low detection levels special care must
be taken with the instrumentation, operators,
laboratory environment and any sample
containers used; all of which can impact on
experimental results.

This is equally true for ultrapure water used in
the analytical process. Due to the dissolution
and dilution processes required in sample
preparation, high-purity water typically
constitutes over 90 % of a sample analyzed
by these sensitive techniques. High-purity
water is also used for cleaning sample
containers, washing plastics and preparing
blanks and standard solutions.
Conclusion
The Milli-Q Element system produced ultrapure water of a reliable and reproduciblequality,
suitable for trace element analysis, when fed by Elix system water (resistivity> 5 MΩ.cm at
25 °C, TOC levels < 30 ppb). Additionally using the specially designed, foot-pedal
operated hands-free dispenser under clean-room conditions further enhanced final product
water quality delivered by the Milli-Q Element system.

Laboratories performing trace analysis
must have a reliable source of ultrapure
water with consistently low elemental
concentrations. The Milli-Q Element ultrapure
water system was specifically designed for
this purpose by scientists conversant with
trace analysis methods such as IC, ICP-MS
and GF-AAS.
Milli-Q Element Ultrapure Water
System
The Milli-Q Element system employs
ultra-clean materials and a succession of
optimized water purification technologies to
produce 18.2 MΩ.cm resistivity ultrapure
water (at 25 °C), ideal for
trace analysis methods.
Foot-pedal activation
is available to allow
hands-free delivery in a
clean room, further
reducing the possibility of
contamination, as well as a
remote display providing
information on all system
parameters.

Reproductibility of Low Elemental Concentrations
Experimental studies have demonstrated that the Milli-Q Element system not only
provides ultrapure water, with extremely low levels of elemental concentrations, but
also reliably and consistently delivers the same high water quality on a continuous
basis. The analytical scientist can consider the ultrapure water quality from a Milli-Q
Element system as an experimental constant.
The data below (Graphs 1-3) shows the results from an experiment comparing the
quality of Milli-Q Element product water from the same system delivered either via a
hands-free dispenser under a laminar flow hood (using foot-pedal operation), with a
0,1 µm Optimizer® filter or via a hand-held point-of-use dispenser with a 0,22 µm
Millipak® end filter. These results demonstrate that the hands-free point-of-use dispenser
designed specifically for the Milli-Q Element system, which allows the product water
to be delivered under a laminar flow hood, improves the quality and reproducibility
of the ultrapure water produced.

Recent advancements in measuring techniques
and detection technologies have dramatically
improved the sensitivity of modern analytical
instrumentation. Trace elements can now be
measured at ppt and sub-ppt levels using
techniques such as ICP-MS.

These low detection levels allow new
applications, such as elemental
fingerprinting, to be employed in such
diverse fields as forensic science, the food
and beverage industry and astrogeology.
With low detection levels special care must
be taken with the instrumentation, operators,
laboratory environment and any sample
containers used; all of which can impact on
experimental results.

Element
This is equally true for ultrapure water used in
the analytical process. Due to the dissolution
and dilution processes required in sample
preparation, high-purity water typically
constitutes over 90 % of a sample analyzed
by these sensitive techniques. High-purity
water is also used for cleaning sample
containers, washing plastics and preparing
blanks and standard solutions.
Conclusion
The Milli-Q Element system produced ultrapure water of a reliable and reproduciblequality,
suitable for trace element analysis, when fed by Elix system water (resistivity> 5 MΩ.cm at
25 °C, TOC levels < 30 ppb). Additionally using the specially designed, foot-pedal
operated hands-free dispenser under clean-room conditions further enhanced final product
water quality delivered by the Milli-Q Element system.

Laboratories performing trace analysis
must have a reliable source of ultrapure
water with consistently low elemental
concentrations. The Milli-Q Element ultrapure
water system was specifically designed for
this purpose by scientists conversant with
trace analysis methods such as IC, ICP-MS
and GF-AAS.
Milli-Q Element Ultrapure Water
System
The Milli-Q Element system employs
ultra-clean materials and a succession of
optimized water purification technologies to
produce 18.2 MΩ.cm resistivity ultrapure
water (at 25 °C), ideal for
trace analysis methods.
Foot-pedal activation
is available to allow
hands-free delivery in a
clean room, further
reducing the possibility of
contamination, as well as a
remote display providing
information on all system
parameters.
