There are basically two types of analysis which can be conducted upon collected residues. The first type of analysis is conducted by scanning electron microscopy (SEM) upon residues which have been collected on sticky metal stubs. The second type of analysis is conducted by atomic absorption (AA) analysis upon residues which have been collected on cotton-tipped swabs. Be sure to check with your forensic laboratory to determine which type of analysis they conduct.
