Automating even the most demanding
titration
Automation now plays a vital and cost effective way of carrying out many titration tasks
With the ever increasing work load that chemists face, and in many cases a reduction in personnel, you can't afford to ignore the power and help that automation can bring to your business When should a sample changer system be used? For large numbers of samples

Analysis of water hardness by automated titration
The major contributors to the hardness of a water sample are generally regarded as dissolved calcium and magnesium ions, which combine with soap to form insoluble precipitates
Where the sample must be dissolved immediately before the titration.
Where the highest precision and reproducibility is demanded.
Lower cost analysis.
Greater sensitivity in the detection of end-points through mathematical evaluation Error-free documentation of analysis results on-line to Lims.
The benefits of automating your titration system: High sample throughput.
Operator requires no special knowledge.
Operational personnel are freed for the duration of the analysis.
Contact with toxic chemical is reduced to a minimum.
The system can operate seven days a week for twenty-four hours.
No matter how complex or easy your automation, Metrohm says it can help.
For mundane tasks it recommends the flexible USB 814 sample processor in conjunction with the Titrando range of titrators.
This system boasts many features including rinsing and aspirating of sample and calibration and regeneration of electrodes, with many standard and specially manufactured sample racks available.
If more capacity is required then the USB robotic 815 XL sample processor offers this.
Of course a twin head option is available.
This is particularly useful when one may have aqueous and non-aqueous titrations to perform, or conductivity and pH measurements on the same sample.
With a maximum of 999 positions available there has never been a more flexible solution to your automation wishes.
Both sample processor systems are controlled through Titrando software be it Touch screen or PC control.
Software control for high performance combined titration systems.
Together with Metrohm's Titrando 835 or/and 836, allows the creation of extension possibilities which even the most expensive titrators cannot achieve and of course it is CFR 21 Part 11 compliant.The operation of the system is childishly easy.
Depending on the task and program, the following can be controlled: Simultaneous control and monitoring, on the PC/Touch screen, of titration sequences from several Titrandos.
Use of 'intelligent dosing unitsi with plausibility function.
Editing, storage and recall of methods.
Recalculation of results by re-evaluating with modified parameters without repeating the determination.
Demanding operations with a sample changer performed fully automatically, 24hrs a day seven days a week.
ISE measurement and titration on the same sample using the same instrument.
Link to Lims or server based systems.
Metrohm says it has special package prices for all automation until the end of June. Request a free brochure from Metrohm UK ...
