Some issues with the Adult RTFs apparent: products not thought to be viable (TCP fallout)
ICP-MS results from 5-6 MLT labs mostly higher than ICP-AES results from Abbott (6day x 2 means)
P results are higher, but not really different from any other element; full SRM results shown below, showing old (SLV) result for Abbott
SRM 1849a Results (mg/kg) at MLT sites
Sample codes are paired as the blind duplicates, each Mean is the average of duplicate determinations, required by the method
