“Plug and Play” Polarographic Analyser
Trace analysis have never been important than today where detection of heavy metals and other pollutant compounds requires a continuos surveillance in many samples like water, food, beverages etc. For the first time a high performance static mercury drop electrode and a COMPLETE COMPUTERISED TRACE ANALYSER have been put together in a single, compact enclosure to produce the most sophisticated instrument never conceived for polarographic and voltammetric research and applications.
The Model 433-A is a really complete unit requiring no external accessories to be put in work: just connect it to any personal computer and you are up and ready for your analysis.
The instrument in fact is supplied with a Windows© software without any price increase.
- Trace analysis of metals at 1µg/l level
- Analysis of organic compounds
- Ideal for quality and process control laboratory
- High versatility for research
Mercury Valve, the instrument's heart
Most of the exceptional performance of the 433 relies on the unique design of the mercury-dispensing device and capillary.
Any problems present in other similar instruments have been completely removed: no pressurisation, no mechanics in direct contact with mercury, perfect reproducibility of mercury drop, use of simple and easy replaceable capillaries grant a long working life with unaltered accuracy.
A fully-equipped cell head
The supporting block contains a complete set of electrodes, two-way gas purging inlet/outlet, sample injection port and full sealing to insure a complete tightness of the cell (available in different materials and shapes).
A rotating-field magnetic stirrer provides accurate solution stirring during sample purging or anodic stripping. All parts in contact with the solution are made in Teflon®, Viton® or Silicone Rubber® for long life and minimum pollution of samples. The built-in electrodes can be easily removed for cleaning, refilling or to be replaced with external ones: for this purpose a set of connections is made available on the cell block itself.
No longer mercury free on the lab.
he mercury reservoir is another unique AMEL innovation: made completely out of polypropilene, it is fully sealed with respect the outside ambient allowing safe operation under any condition without risks for ambient pollution. A plastic rotating cock allows complete isolation of the reservoir from the valve in order to replace the latter without empty the former. The large reservoir capacity (about 3 kg) allows months of continuous operation without refilling need; the tightness of the reservoir preserves the mercury from pollution and dust. The 433 can be moved around in the lab or even transported by car for short distances filled up without spillage risk!
