Foodstuffs. Determination of trace elements. Pressure digestion Ingestion-build-221493 The passive optical device (component)1 Scope This European Standard specifies a method for the pressure digestion of foodstuffs intended for the determination of elements. This method has been collaboratively tested in combination with atomic absorption (flame, electrothermal (ET), hydride, cold vapour) techniques and ICP MS. Other techniques such as e. g. ICP OES, voltammetry or atomic fluorescence can be used in combination with this European Standard.
