Inductively coupled plasma atomic emission spectrometric determination of aluminium, barium, silicon, strontium and titanium in food after sample fusion.

A rapid and accurate method for the inductively coupled plasma atomic emission spectrometric determination of Al, Ba, Si, Sr and Ti in food was developed based on a direct lithium metaborate fusion without sample pre-ashing. Six NIST diet test samples were analysed. Three independent sample preparation procedures were compared for verification.
