Each Spike sample contains 175-250 micrograms of Lead per wipe. Using an NIST Traceable solid sample, known amounts are placed on a GhostWipe and individually labeled with the exact amount of lead each wipe contains. Samples are packaged in a rigid walled container (see our SC475 cup) that meets all parameters of E1792.
