This document specifies a procedure for the direct determination of the content of the soap building elements Calcium (Ca), Magnesium (Mg), Sodium (Na) and Potassium (K) as well as Phosphorus (P) in fatty acid methyl esters (FAME) by ICP OES.
The concentrations of each component or the combinations of some to which this method is applicable are given in Table 1.
Table 1 - Scope ranges for each element
Element  Scope range
mg/kg
Ca  0,3 - 5,4
Mg  0,3 - 4,6
Na  0,4 - 5,0
K  0,6 - 5,3
P  1,0 - 5,0
Ca + Mg  0,5 - 9,4
Na + K  1,0 - 9,9
Ca + Mg + Na + K  1,4 - 19,3
