One of the keywords that describes us at Zimmer and Peacock is electrochemistry and so we approach the development of sensors and sensing from an electrochemist's perspective. That is why when people ask us can we provide or develop a sensors for heavy metal detection the answer is YES, but most importantly we also approach the answer form the perspective than for an electrochemist heavy metal detection is an 'easy' and well understood technology.
In the adjacent image we show the wave form and expected raw data from analysing a solution of heavy metals.
The technique that we recommend is anodic stripping which is an analytical technique that involves preconcentration of a metal onto an electrode surface followed by selective oxidation of each metal during an anodic potential sweep.
Stripping analysis has the following properties:
The method is quantitative a the stripping peak currents and peak widths are a function of the metal concentration in solution.
In the buttons below we have linked to the instrument and electrodes for starting your development, if you have any questions regarding Zimmer and Peacock please don't hesitate to contact us.
