Looking for Lead and Copper in Drinking Water

Friday, 29 August

The US EPA-approved SA-1000 Scanning Analyser from Palintest Ltd. uses tiny, disposable electrode sensors to provide fast, accurate on-site testing for lead and copper concentrations in potable water.

Portable testing for these elements has traditionally suffered from a limiting lack of precision, but Palintest's simple technique – enabled by complex technology – provides results that are comparable to those obtained from lab-based atomic absorption methods.

No complex sample preparation is required; a conditioning tablet is added to the water and then the electrode is inserted. The battery-powered SA-1000 then applies varying currents and potentials in order to determine the scale of lead and copper ion presence down to levels as low as 5 µg/l. The testing method is fully approved by the US EPA. Results are then saved in the unit's memory and can be easily uploaded on to a PC for reporting purposes. The testing process takes only three minutes and requires no special training or additional equipment, providing a cost-effective solution to potable water testing.
