Scope

This Standard specifies the graphite furnace atomic absorption spectrometry,
atomic fluorescence spectrometry, inductively coupled plasma mass
spectrometry, inductively coupled plasma emission spectrometry, and
malachite green spectrophotometry for the determination of stibium migration
after food contact materials and articles are soaked in food simulants.
This Standard is applicable to the determination of stibium migration in food
contact materials and articles.
Method One -- Graphite furnace atomic absorption
spectrometry
2 Principle
Use the food simulant to immerse the parts of food contact materials and
articles intended to come into contact with food. Soaking solution is atomized
by graphite furnace. The absorption value measured at 231.2 nm is proportional
to the cerium content over a range of concentrations. Compare and quantify
with the standard series.
