Abstract

Sample preparation had always been a tedious but important step in analysis involving Inductively Coupled plasma emission spectrometry. In addition it might also be a source of sample contamination. The present work attempted to overcome these problems by nebulizing milk powder suspensions directly into the plasma. Various infant and full cream milk powders were dispersed in water as well as 0.5 triton-X solution. The suspensions were then analysed for calcium phosphorus iron magnesium and sodium. These elements were successfully determined using inorganic standards with the addition of an internal standard to correct for the difference in viscosities
