In an analysis of the quantity of lead in aqueous solution with aqueous solution can provide the analysis rarely better than AA, because there must be a dilution so that there is a difference of more than metrix.
In the analysis of lead in solution may provide a plating solution analysis than AA because I need to be diluted. It has the distinction of metrix over.
In the determination of lead in aqueous solution plating solution may provide an uncomfortable that AA because there must be diluted, so there are differences. Metrix.
