ISO 7485:2000

Animal feeding stuffs -- Determination of potassium and sodium contents -- Methods using flame-emission spectrometry

PUBLISH DATE 2000
ISO 7485:2000

This International Standard specifies a calibration method and a standard addition method for the determination of potassium and sodium contents of animal feeding stuffs by flame-emission spectrometry.

The standard addition method applies if it is not known whether the emissions measured for potassium or sodium are subject to matrix effects. The limit of determination for potassium and sodium is 0,04 g/kg.

The calibration method applies if such matrix effects have been shown to be absent.
