Description

1.1”Most atomic absorption and plasma emission spectroscopy, and plasma-mass spectrometric test methods require that the metals of interest be dissolved in a liquid phase before being introduced into the spectrophotometer. These practices describe digestion or dissolution procedures whereby analyte metals associated with the solid fraction of a sample can be brought into solution for subsequent analysis. The following practices are included:

”	Sections
Practice A”’Digestion with Mineral Acids and ”’Elevated Pressure	”’8 through 13
Practice B”’Digestion with Mineral Acids and ”’Heating at Atmospheric Pressure	14 through 19
Practice C”’In-Bottle Digestion with Mineral Acids	20 through 25
