AACCI Method 40-75.01
Determination of Minerals by Inductively Coupled Plasma Spectroscopy

VIEW METHOD

Objective
Samples are ashed in a muffle furnace to remove organic material, and the ash residue is dissolved in dilute acid. The concentration of minerals is determined by comparing the emissions of the unknown sample to standard solutions, measured by inductively coupled plasma (ICP) atomic emission spectroscopy. This method measures calcium, cobalt, copper, iron, potassium, magnesium, manganese, sodium, phosphorus, and zinc in grains and grain products.
