APPLICATIONS OF EMISSION SPECTROSCOPY
In general, prepare not fewer than three reference solutions of the element to be determined covering the concentration range recommended by the manufacturers for the element and instrument used. Any rea-gent used in preparing the solution of the substance being examined must be added to the reference solution in the same concentration. Besides, where solids are present in solutions they may give rise to interferences and for that reason the solid content of the solutions must be below 2% wherever possible.
· Emission spectroscopy has been employed for the analysis of various alloys, namely : aluminium, copper, magnesium, zinc, lead, and tin.
· It has been used for the analysis of a number of elements, for instance : Na, K, Zn, Cu, Ca, Mg, Ni and Fe present in various tissues of human beings. Changes in trace-metal concentrations have been studied at length with regard to the ageing process.
· Trace amounts of Ca, Cu, and Zn have been examined in blood samples.
· Presence of Zn has been examined in the pancreas tissue.
· To determine the extent of elements present in ‘crude oil’ by virtue of the fact that some of these may poison the catalysts used in the cracking-process e.g., V, Cu, Ni, and Fe.
