Sample preparation of powders for trace metal analysis

  1. Sep 26, 2016 #1
    When preparing a fine powder for trace metal analysis, is ashing prior to digesting unnecessary? If not, or not necessarily, where could I learn more about important considerations to determine whether of not any preparation prior to digestion is required?

    The one instance I have come across thus far for milk powder says it is easily digested - which suggests to me that there is no prior preparation necessary.

    Im specifically looking at low-fat organic matrices at this stage
