Fitness for Purpose
Draft Fitness for purpose statement (FFP)
A method for the determination of the major chemical species present
in selected food matrices of any of the following elements: Arsenic,
Mercury, Cadmium or Lead.
For the purpose of this Fitness for Purpose statement:
The method should be able to speciate and quantify the major forms
(summing to >85% of total) of the element present in the food
matrix Separation of the species should be achieved through the use
.
of liquid chromatography or ion chromatography that is interfaced to
Inductive Coupled Plasma Mass Spectroscopy (ICP‐MS)
technology. Methods should specify which matrix materials are
acceptable for examination of the elemental speciation. Methods may
be single matrix applicable. The Limit of Quantitation (LOQ) of an
individual speciated elemental form should be below 15 parts per
billion (ug/kg).
