3. Analysis strategy

Having dealt with the analytical methods individually, it's a good idea to combine them in order to obtain the maximum amount of relevant information about the suspect sample. A summary table (Table 1 ) puts all these techniques into perspective, specifying the cost of the equipment, the speed of analysis (from sample preparation to interpretation of results) and the level of expertise required of the analyst. Please note that the information in this table is general and can be refined on a case-by-case basis.
