Quantitative Analysis of Metals in Aqua Regia and PCB Material

We are seeking laboratory services to determine the presence and concentration of gold (Au), silver (Ag), platinum (Pt), copper (Cu), mercury (Hg), protactinium (Pa), and tin (Sn) in two sample types: (1) solutions obtained by dissolving material in aqua regia, and (2) dry powdered samples from ground printed circuit boards (PCBs). The analysis should include accurate quantification of each element.
