34  LMS  Issue 2 | 2014 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. ⚛ Monitoring & Control Laboratories Tel: 011-608-4664 Fax: 011-608-4741 Email: [email protected] 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. ⚛ Anatech Instruments Tel: 011-462‑6776 Fax: 011-704‑6490 Email: [email protected] 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. ⚛ Microsep Contact: Rudy Maliepaard Tel: 011-553‑2300 Email: [email protected]
