SA-4000 Scanning Analyzer

As a result of current legislation on the release of lead and cadmium from ceramic surfaces by the FDA (Food and Drug Administration) and California State, manufacturers of ceramic ware wishing to export their products to the USA must ensure compliance with the appropriate regulations. For this purpose, a rapid, cost effective, accurate method of analysis for metal levels in the process control environment is essential. To this end, the SA-4000 was developed.

Based on the established technique of differential pulse anodic stripping voltammetry, the instrument uses detachable disposable electrodes to simultaneously test for lead and cadmium in ceramic leachate.

The leachate is prepared as specified by the Association of Official Analytical Chemists (ADAC) - a 24 hour soak of the vessel in 4% acetic acid. A 5 ml aliquot of the leachate is taken and a conditioning tablet is added to it. The sample is now ready for testing.
