Laboratory
The produced lead ingot samples are analysed carefully to ensure the highest quality. Lead samples spun from the ingots in the form of a puck are analysed to determine the concentration of lead metal impurity elements.
For reliable results, the sample surface must be perfectly straight and free of any dirt. After spinning, the samples are tested with a spark emission spectrometer.
The EcoLead emission spectrometer uses an established method based on certified standard materials, ensuring that its products comply with the standard EN 12659:1999.
