ELEM ENT S O N W IPES: M ETH OD 9102, Issue 1, dated 1 5 Ma rch 2003 - Page 4 of 5 Be cause this m eth od is a simultaneous elemental analysis, it is not compound specific. The data provided is for those com pounds com patible with the acids used in the digestion . Ve rificatio n of the solubility of specific compounds of interest should be com pleted and the sam ple m atrix carefully exam ined. F or exam ple, if silicates are pre sent to tal elem ental values will not be m easured witho ut th e use of h ydrofluoric acid in the digestion process.
