Water Analysis & Purification
A Smart, Handheld, Versatile Sensor
T
he YSI ProODO optical dissolved
oxygen sensor utilises Optical
Dissolved Oxygen (ODO®) technology
in order to take an oxygen measurement.
This handheld instrument is designed
for sampling applications.
The ODO luminescent sensor has no
flow dependence making it the perfect
choice for applications like deep water
profiling, where stirring is difficult. The
lack of flow dependence also reduces
the possibility of operator error due
to inadequate stirring, ensuring high
quality data.
The greater stability of optical technolog y offers additiona l va lue by
reducing calibrations, thus reducing
maintenance costs. The technology is
resistant to probe fouling from hydrogen sulfide. The smart, digital ODO
probe stores calibration data so probes
can be interchanged between instruments without recalibration.
With the ProODO customers can
expect 90% of their reading in 25
seconds. This instrument is rated to
IP-67 standards even without the
batter y cover on. Inhouse testing
procedures include 1m drop tests from
all angles. Other features include a
three-year instrument warranty and
a two-year cable and probe warranty.
The instrument offers numerous
bene its including a 5000 dataset
f
memor y, e x panded DO range of
0-500% (0-50mg/l), OBOD optical and
a self-stirring BOD probe for the lab.
Any length cable and probe can be connected to the digital series instrument.
The digital-based sensors hold calibration data and allow one to connect easily
to any ProODO instrument. ⚛

Dionex Joins Anatech
D
ionex, a leader in ion chromatography, is now represented in SA by Anatech Instruments. With this
partnership they are pleased to launch the world’s first high
pressure capillary IC, the ICS 4000.
The ICS 4000 is always on and always ready for routine
applications. Low flow rates combined with
Reagent-Free™ IC technology allows
months of operation with just 1l of
water.
It has an integrated system with
options for conductivity, electrochemical and charge detection capabilities, and can be run isocratically
or using a gradient.
Due to the low flow rates and high
pressure, it is able to achieve faster
separations at a lower price.
Anatech have invested heavily in the
training of service staff, applications
staff and sales staff to give the best
support possible.
In addition, they offer both IC training packages as well as Chromeleon™
training packages inhouse or at their
premises in Randburg.
One no longer has to look elsewhere
for the best product, friendly and
p
rofessional service, and excellent
support.
Vanessa Bunn, Sales Manager at
Anatech, says, “We are delighted to
add this product range to our portfolio,
it complements our range, and we have
already had success with installs of this
top class product.”
In addition to this system, Dionex
have upgraded all their existing lines. ⚛

Titration with a Difference
M
ettler Toledo’s T70 Excellence
titrators with InMotion autosamplers offer a fully automated titration system with maximum sample
throughput (up to 313 samples) for
water analysis.
The Excellence line features
One Click Titration™,
a milestone in
solutions for
simple,
efficient
and
secure titration. Benefits include modularity, flexible user
management,
intuitive user
interface, a personal home screen, automatic burette recognition and plug, and
play sensors. Operation is easy because
of the method concept and touchscreen.
A single sample or an entire series of
samples can be started with just one touch
to the shortcut key.
The new InMotion autosamplers offer
a waterbath version, which allows one to
run all samples at the same temperature
to eliminate discrepancies in results due
to temperature differences.
Another unique feature is that the
titration head is able to stop at two alternative sample heights.
Typically, the conductivity sensor is
positioned lower than the other electrodes
and tubes to minimise contamination, as
it stops at the first down position during
multiparameter analysis.
After the conductivity measurement is
complete, the head will move down completely to submerge the other electrodes.
LabX Titration has now migrated
to the LabX 2014 platform, providing
the convenience of a centrally managed
software system that controls several
different instruments. ⚛
