In the Maker Shed: Detection of lead paint test kit


The Detection of lead paint test kit provides the equipment and reagents you need to perform reliable multi-step laboratory tests for detecting lead content in paints. The sulfide test, a sensitive preliminary screening test, quickly identifies paint samples that may contain lead (but may instead contain only traces of cobalt or other innocuous metals that yield a false positive with the sulfide test). Samples that test tentatively positive with sulfide reagent can subsequently be subjected to confirmatory tests with chromate and iodide reagents, each of which produces a characteristic precipitate in the presence of lead.

The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for 'projects in a box,' otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .
